Writing Notes: Carbon Monoxide Poisoning

Carbon monoxide (CO) poisoning - occurs when carbon monoxide gas is inhaled.

CO - a colorless, odorless, highly poisonous gas.

Produced by incomplete combustion.

Interferes with the ability of the blood to carry oxygen.

Found in: automobile exhaust fumes, faulty stoves and heating systems, fires, and cigarette smoke.

Other sources: woodburning stoves, kerosene heaters, improperly ventilated water heaters and gas stoves, and blocked or poorly maintained chimney flues.

The result is headache, nausea, convulsions, and finally death by asphyxiation.

Symptoms

The symptoms of CO poisoning in order of increasing severity include:

headache

shortness of breath

dizziness

fatigue

mental confusion and difficulty thinking

loss of fine hand-eye coordination

nausea and vomiting

rapid heart rate

hallucinations

inability to execute voluntary movements accurately

collapse

lowered body temperature (hypothermia)

coma

convulsions

seriously low blood pressure

cardiac and respiratory failure

death

In some cases, the skin, mucous membranes, and nails of a person with CO poisoning are cherry red or bright pink. Because the color change doesn’t always occur, it is an unreliable symptom to rely on for diagnosis.

Although most CO poisoning is acute, or sudden, it is possible to suffer from chronic CO poisoning. This condition exists when a person is exposed to low levels of the gas over a period of days to months.

Symptoms are often vague and include (in order of frequency) fatigue, headache, dizziness, sleep disturbances, cardiac symptoms, apathy, nausea, and memory disturbances.

Little is known about chronic CO poisoning, and it is often misdiagnosed.

Treatment

Immediate treatment: Remove the victim from the source of carbon monoxide gas and get him or her into fresh air.

If the victim is not breathing and has no pulse, cardiopulmonary resuscitation (CPR) should be started.

Depending on the severity of the poisoning, 100% oxygen may be given with a tight fitting mask as soon as it is available.

Taken with other symptoms of CO poisoning, COHb levels of over 25% in healthy individuals, over 15% in patients with a history of heart or lung disease, and over 10% in pregnant women usually indicate the need for hospitalization.

In the hospital, fluids and electrolytes are given to correct any imbalances that have arisen from the breakdown of cellular metabolism.

In severe cases of CO poisoning, patients are given hyperbaric oxygen therapy. This treatment involves placing the patient in a chamber breathing 100% oxygen at a pressure of more than one atmosphere (the normal pressure the atmosphere exerts at sea level). The increased pressure forces more oxygen into the blood.

Prevention

Carbon monoxide poisoning is preventable.

Particular care should be paid to situations where fuel is burned in a confined area. Portable and permanently installed carbon monoxide detectors that sound a warning similar to smoke detectors are available for less than $50.

Specific actions that will prevent CO poisoning include:

Stopping smoking. Smokers have less tolerance to environmental CO.

Having heating systems and appliances installed by a qualified contractor to assure that they are properly vented and meet local building codes

Inspecting and properly maintaining heating systems, chimneys, and appliances

Not using a gas oven or stove to heat the home

Not burning charcoal indoors

Making sure there is good ventilation if using a kerosene heater indoors

Not leaving cars or trucks running inside the garage

Keeping car windows rolled up when stuck in heavy traffic, especially if inside a tunnel.

Carbon Capture and Storage: A Key to Achieve Net-Zero Targets

Amidst rising CO2 emissions, renewable energy sources and improving energy efficiency are critical components of climate change solutions. One of the most promising technologies to mitigate industrial carbon emissions is Carbon Capture and Storage (CCS). This innovative technology provides a pathway to capture CO2 emissions before they enter the atmosphere, significantly reducing their impact on the environment. According to the International Energy Agency’s (IEA) Sustainable Development Scenario, Carbon Capture, Utilization, and Storage (CCUS) technology could account for nearly 15% of the total emissions reduction needed to achieve global net-zero targets by 2070. This highlights CCUS as a key component in addressing climate change and meeting long-term sustainability goals.

Carbon Capture and Storage (CCS) is no longer a far-off vision of the future but a practical solution to today’s climate crisis. CCS is also recognized as an essential tool to meet the Paris Agreement’s target of limiting global temperature rise to below 2°C. According to the Global CCS Institute, to meet these goals, the world would need to increase CCS capacity from the current 40 million tons annually to around 5.6 billion tons per year by 2050.

What is Carbon Capture and Storage?

Carbon Capture and Storage (CCS) is a carbon emissions reduction technology designed to capture and securely store CO2 produced by industries. It is utilized in industries like steel, cement, and power generation, where emissions are difficult to decarbonize. The CCS process can be broken down as follows:

Capture: CO2 is separated from other gases in industrial processes using advanced carbon capture technology.

Transport: Captured CO2 is then transported via pipelines, ships, or other means to a designated storage site.

Storage: CO2 is stored deep underground in geological formations, such as depleted oil and gas reservoirs or saline aquifers, preventing its release into the atmosphere.

The Technologies behind Carbon Capture and Storage

The most common CO2 storage methods involve geological formations. These include depleted oil and gas reservoirs, saline aquifers, and unmineable coal seams. A successful example of geological CO2 storage is Norway’s Sleipner project, which has been storing approximately 1 million tons of CO2 annually in a saline aquifer beneath the North Sea since 1996. Other carbon capture methods are generally classified into three primary approaches:

Pre-Combustion Carbon Capture: This method captures CO2 before the fuel is burned, making it particularly suitable for industries that convert coal, oil, or gas into fuel gas. Pre-combustion capture typically involves gasifying the fuel to produce a mixture of hydrogen and CO2. The CO2 is then separated and captured for storage.

Post-Combustion Carbon Capture: The method involves capturing CO2 from the flue gases emitted after fossil fuels are burned. This approach is widely applicable to power plants and various industrial facilities. A notable example is the Boundary Dam power station in Canada, which captures approximately 1 million tons of CO2 annually through post-combustion capture.

Oxyfuel Combustion Technology: This process involves burning fuels in oxygen rather than air, resulting in a concentrated stream of CO2, which makes it easier to capture. This method is still being developed and tested but holds promise for future CCS projects.

Once captured, CO2 must be transported to storage sites. Pipelines are the most common mode of CO2 transportation, particularly for large-scale carbon capture and storage systems. Currently, more than 6,500 kilometers of CO2 pipelines are in operation globally, especially in regions like the US and Canada, which have well-established infrastructure for CCS and carbon capture utilization and storage (CCUS).

Real-World Applications of Carbon Capture and Storage

Around the world, CCS projects are already in action as power generation is a major source of CO2 emissions. Implementing CCS in power plants has proven effective in reducing their environmental impact. For instance, the Petra Nova power station in Texas employed a CCS system that captured over 1.6 million tons of CO2 annually during its operation from 2017 to 2020.

The Gorgon Project in Australia is one of the largest CCS initiatives in the world, aiming to store 4 million tons of CO2 annually in an offshore gas field. Such large-scale projects demonstrate the feasibility of CCS in combating industrial emissions.

Similarly, the Drax Group in the UK, which operates the country’s largest power station, plans to capture 8 million tons of CO2 annually as part of its bioenergy with carbon capture and storage (BECCS) project. In January 2024, the UK government approved Drax’s plan to convert two of its biomass units into carbon capture and storage stations for bioenergy.

Challenges and Opportunities in Carbon Capture and Storage

While the potential of Carbon Capture and Storage (CCS) is promising, several challenges remain. The cost of implementing CCS technology remains high. Estimates suggest that capturing CO2 can cost between $60 to $100 per ton, depending on the technology and source. The IEA forecasts that the cost of carbon capture and storage (CCS) could decrease significantly in the coming years, primarily due to increased deployment and technological advancements. In addition to the costs, developing the infrastructure required for CCS, such as pipelines and storage facilities, demands substantial investment. Countries without established pipelines or suitable geological storage sites face logistical challenges. Most importantly, public concern about the safety of storing CO2 underground and a lack of clear government policies have slowed the widespread adoption of CCS.

However, despite these financial and regulatory hurdles, varied opportunities are paving the way for stakeholders to explore the full potential of CCS. Active R&D efforts are leading to more efficient and cost-effective CCS technologies. Innovations in materials for CO2 capture, such as advanced solvents and membranes, are expected to further drive down costs. Governments are increasingly recognizing the role of CCS in meeting climate goals. For instance, the US Infrastructure Investment and Jobs Act passed in 2021 allocated $3.5 billion for CCS projects, and similar investments are being made worldwide.

Future Prospects in Carbon Capture and Storage

Looking ahead, CCS will play a pivotal role in managing CO2 and keeping our planet’s climate in balance. As we strive toward a net-zero future, industries and governments are expected to invest heavily in CCS infrastructure. Countries like China and India, with their heavy reliance on coal, could be key players in adopting CCS to reduce their emissions while maintaining economic growth. From power generation to heavy industry, CCS is proving its ability to significantly curb CO2 emissions. However, realizing its full potential will require overcoming economic and infrastructural challenges, supported by continued innovation, government policy, and investment.

Some Least Known Mechanical Properties of Nickel Alloys

1. Superplasticity in Manufacturing: Certain nickel alloys, such as Nimonic 90, show superplasticity, meaning they can tolerate extreme deformation without failure at high temperatures. This property allows for easier shaping of complex geometries, like turbine blades, without sacrificing material strength.

2. Creep Resistance: Creep refers to the gradual deformation of a material under constant stress at rising temperatures. Nickel alloys, particularly Inconel 718 and Hastelloy X, are designed to resist creep deformation, maintaining their shape over long periods, even in heater components and jet engines where constant thermal cycling occurs.

3. Fatigue Strength: Nickel alloys also excel in fatigue resistance, which is the ability to withstand repeated stress cycles without cracking. This is critical for industries such as aerospace and automotive, where components like engine valves and turbine discs are subjected to constant cyclic loads at high temperatures.

Nickel Alloy Innovations in Modern Applications

1. 3D Printing with Nickel Alloys: Recent advances in additive manufacturing have enabled the use of nickel alloys like Inconel 718 and Hastelloy X in 3D printing. These alloys, in powder form, are used to create complex, high-performance components for aerospace and defence, offering reduced material waste and increased design flexibility.

2. Nickel-Aluminide Alloys for High-Temperature Industrial Equipment: Nickel-aluminides, a class of nickel alloys, have gained attention for their exceptional strength and oxidation resistance at temperatures exceeding 1200°C. These alloys are now being deployed in combustion chambers for power plants due to their combination of low density and high durability.

3. Nickel-Titanium Shape Memory Alloys: Nickel alloys also have niche applications in shape memory technology. Nickel-titanium (Nitinol) is widely used in the medical field. When damaged, Nitinol can return to its original shape when exposed to heat, offering high fatigue resistance and durability in high-performance environments.

Nickel alloys are essential for industries where extreme conditions are the norm. Selecting the right alloy is crucial for ensuring durability and performance. For instance, understanding the differences between fasteners made from Inconel 600 or Monel can significantly influence your application’s success. By making informed choices, businesses can reduce maintenance costs and guarantee the longevity of their components.

Capturing carbon from the air just got easier

A new type of porous material called a covalent organic framework quickly sucks up CO2 from ambient air

Date:October 23, 2024Source:University of California - BerkeleySummary:In the face of rising CO2 levels, scientists are searching for sustainable ways of pulling carbon dioxide out of the air, so-called direct air capture. A new type of porous material, a covalent organic framework (COF) with attached amines, stands out because of its durability and efficient adsorption and desorption of CO2 at relatively low temperatures. The material would fit into carbon capture systems currently used for point source capture.Share:

    

FULL STORY

Capturing and storing the carbon dioxide humans produce is key to lowering atmospheric greenhouse gases and slowing global warming, but today's carbon capture technologies work well only for concentrated sources of carbon, such as power plant exhaust. The same methods cannot efficiently capture carbon dioxide from ambient air, where concentrations are hundreds of times lower than in flue gases.

Yet direct air capture, or DAC, is being counted on to reverse the rise of CO2 levels, which have reached 426 parts per million (ppm), 50% higher than levels before the Industrial Revolution. Without it, according to the Intergovernmental Panel on Climate Change, we won't reach humanity's goal of limiting warming to 1.5 °C (2.7 °F) above preexisting global averages.

A new type of absorbing material developed by chemists at the University of California, Berkeley, could help get the world to negative emissions. The porous material -- a covalent organic framework (COF) -- captures CO2 from ambient air without degradation by water or other contaminants, one of the limitations of existing DAC technologies.

"We took a powder of this material, put it in a tube, and we passed Berkeley air -- just outdoor air -- into the material to see how it would perform, and it was beautiful. It cleaned the air entirely of CO2. Everything," said Omar Yaghi, the James and Neeltje Tretter Professor of Chemistry at UC Berkeley and senior author of a paper that will appear online Oct. 23 in the journal Nature.

"I am excited about it because there's nothing like it out there in terms of performance. It breaks new ground in our efforts to address the climate problem," he added.

According to Yaghi, the new material could be substituted easily into carbon capture systems already deployed or being piloted to remove CO2 from refinery emissions and capture atmospheric CO2 for storage underground.

UC Berkeley graduate student Zihui Zhou, the paper's first author, said that a mere 200 grams of the material, a bit less than half a pound, can take up as much CO2 in a year -- 20 kilograms (44 pounds) -- as a tree.

"Flue gas capture is a way to slow down climate change because you are trying not to release CO2 to the air. Direct air capture is a method to take us back to like it was 100 or more years ago," Zhou said. "Currently, the CO2 concentration in the atmosphere is more than 420 ppm, but that will increase to maybe 500 or 550 before we fully develop and employ flue gas capture. So if we want to decrease the concentration and go back to maybe 400 or 300 ppm, we have to use direct air capture."

COF vs MOF

Yaghi is the inventor of COFs and MOFs (metal-organic frameworks), both of which are rigid crystalline structures with regularly spaced internal pores that provide a large surface area for gases to stick or adsorb. Some MOFs that he and his lab have developed can adsorb water from the air, even in arid conditions, and when heated, release the water for drinking. He has been working on MOFs to capture carbon since the 1990s, long before DAC was on most people's radar screens, he said.

Two years ago, his lab created a very promising material, MOF-808, that adsorbs CO2, but the researchers found that after hundreds of cycles of adsorption and desorption, the MOFs broke down. These MOFs were decorated inside with amines (NH2 groups), which efficiently bind CO2 and are a common component of carbon capture materials. In fact, the dominant carbon capture method involves bubbling exhaust gases through liquid amines that capture the carbon dioxide. Yaghi noted, however, that the energy intensive regeneration and volatility of liquid amines hinders their further industrialization.

Working with colleagues, Yaghi discovered why some MOFs degrade for DAC applications -- they are unstable under basic, as opposed to acidic, conditions, and amines are bases. He and Zhou worked with colleagues in Germany and Chicago to design a stronger material, which they call COF-999. Whereas MOFs are held together by metal atoms, COFs are held together by covalent carbon-carbon and carbon-nitrogen double bonds, among the strongest chemical bonds in nature.

As with MOF-808, the pores of COF-999 are decorated inside with amines, allowing uptake of more CO2 molecules.

"Trapping CO2 from air is a very challenging problem," Yaghi said. "It's energetically demanding, you need a material that has high carbon dioxide capacity, that's highly selective, that's water stable, oxidatively stable, recyclable. It needs to have a low regeneration temperature and needs to be scalable. It's a tall order for a material. And in general, what has been deployed as of today are amine solutions, which are energy intensive because they're based on having amines in water, and water requires a lot of energy to heat up, or solid materials that ultimately degrade with time."

Yaghi and his team have spent the last 20 years developing COFs that have a strong enough backbone to withstand contaminants, ranging from acids and bases to water, sulfur and nitrogen, that degrade other porous solid materials. The COF-999 is assembled from a backbone of olefin polymers with an amine group attached. Once the porous material has formed, it is flushed with more amines that attach to NH2 and form short amine polymers inside the pores. Each amine can capture about one CO2 molecule.

When 400 ppm CO2 air is pumped through the COF at room temperature (25 °C) and 50% humidity, it reaches half capacity in about 18 minutes and is filled in about two hours. However, this depends on the sample form and could be speeded up to a fraction a minute when optimized. Heating to a relatively low temperature -- 60 °C, or 140 °F -- releases the CO2, and the COF is ready to adsorb CO2 again. It can hold up to 2 millimoles of CO2 per gram, standing out from other solid sorbents.

Yaghi noted that not all the amines in the internal polyamine chains currently capture CO2, so it may be possible to enlarge the pores to bind more than twice as much.

"This COF has a strong chemically and thermally stable backbone, it requires less energy, and we have shown it can withstand 100 cycles with no loss of capacity. No other material has been shown to perform like that," Yaghi said. "It's basically the best material out there for direct air capture."

Yaghi is optimistic that artificial intelligence can help speed up the design of even better COFs and MOFs for carbon capture or other purposes, specifically by identifying the chemical conditions required to synthesize their crystalline structures. He is scientific director of a research center at UC Berkeley, the Bakar Institute of Digital Materials for the Planet (BIDMaP), which employs AI to develop cost-efficient, easily deployable versions of MOFs and COFs to help limit and address the impacts of climate change.

"We're very, very excited about blending AI with the chemistry that we've been doing," he said.

The work was funded by King Abdulaziz City for Science and Technology in Saudi Arabia, Yaghi's carbon capture startup, Atoco Inc., Fifth Generation's Love, Tito's, and BIDMaP. Yaghi's collaborators include Joachim Sauer, a visiting scholar from Humboldt University in Berlin, Germany, and computational scientist Laura Gagliardi from the University of Chicago.

Knowledge Sharing Series#2

What is the Process that undergoes in Oil Preheating Furnace?

Crude Oil Entry: The desalted crude oil, which has already been heated and mixed with water to remove salt, enters the preheating furnace.

Heat Exchange: The furnace is typically designed with a series of tubes through which the crude oil flows. Hot flue gases, generated by burning fuel (such as natural gas or fuel oil), pass over these tubes, transferring heat to the crude oil.

Temperature Increase: As the crude oil flows through the tubes, it absorbs heat from the flue gases, gradually increasing in temperature.

Desired Temperature: The furnace is carefully controlled to ensure that the crude oil reaches the desired temperature, typically around 350°C to 360°C. This temperature is essential for effective vaporization of the lighter components in the crude oil.

Exit to Distillation Column: Once the crude oil has reached the target temperature, it exits the preheating furnace and enters the atmospheric distillation column, where the separation process begins.
