Five Reasons for Corrosion Control in Critical Control Rooms

Failures due to corrosion are a common thing in electronics used in control rooms. Critical control rooms need to work without any downtime as the operations are crucial. Electronic process-control equipment which varies from remote sensors to distributed control systems makes any facility functional and operational and keeps them up and running. To achieve this, it requires the correct sensor functioning, communications, and process control. But eventually it is being observed that these critical electronics are catastrophically failing due to the damaging environment in which they are functioning. Please refer the article- Electronics failures and corrosion in industries to know more about the corrosion on electronics.

The working environment must be managed by employing proper corrosion monitoring units and corrosion control equipment to prevent corrosion in control rooms. In this article, let us try to understand the 5 major benefits of corrosion control and monitoring.

 Benefits of Corrosion monitoring and control.

Reduction in the     maintenance cost.

The cost of maintenance of a control room can be phenomenal. Most of the maintenance goes in towards the replacement of sensors or controls which have failed due to corrosion.

 increasing     the longevity of hardware equipment

 The lifespan of electronics working in an unsafe environment will vary from a few weeks or months depending on the severity. For example, a sensor whose lifespan is expected to be 2-3 years might fail within 12-18 months. Adequate Corrosion control measures can increase the lifespan of electronic hardware.

  Prevents operational     losses

 Corroded equipment can disrupt the entire functioning of control rooms when it breaks down causing unexpected delays and loss. Proper monitoring techniques can identify the severity of the operational environment and prevent this disruption from happening.

  Enables a     healthy and safer environment for employees

 Failures due to corrosion not only puts a company’s revenue at risk but also poses a threat towards its employees. Most of the catastrophic failures are due to short circuiting of electronics which is a greater threat towards health and safety of employees as well as the premises. Effective corrosion management can prevent failures of electronics.

  Increases productivity

 All the time saved with good corrosion management will be fruitful towards increasing productivity and revenue.

All electronics, primarily the Printed circuits boards are very susceptible to corrosion under certain conditions. The main reason for this is that the materials selected for the manufacturing of electronics are not inherently corrosion resistant, or even treated to high degrees of resistance

Gaseous Corrosion – Reason for Electronics Failure

All electronics, primarily the Printed circuits boards are very susceptible to corrosion under certain conditions. The main reason for this is that the materials selected for the manufacturing of electronics are not inherently corrosion resistant, or even treated to high degrees of resistance. The electronic equipment fails if the working environment is severe. Replacement of failed electronics is accompanied with an increase in downtime and the risk of health hazards.

How does electronic failure due to corrosion occur?

In this article we will see the major reasons for electronics failure due to corrosion. There are a few major reasons for that.

Corrosion due to manufacturing process

Components like tactile switches are mounted on a PCB by hand soldering technique due to the presence of copper in PCB laminations. Copper has a very high heat capacity and as a result heat is generated during the automated soldering process which results in weaker solder joints. Hand soldering is performed by using a non-clean flux which is believed to leave minimum residue, but in reality it leaves large residues and the level mostly depends on the technical skills of the person performing the soldering operations. The degradation of flux residue happens at 250o-350o C but in case of hand soldering regions near to the solder will experience much lesser temperature leaving a huge amount of unreacted flux on the boards.

This flux residue inside can act as a di-electrical barrier and can cause the equipment to fail at a very early age. The silver and tin used in the electronics are getting corroded easily because of the flux present, as these accelerates the corrosion and this results in a short circuit failure of electronics.

Corrosion due to harmful work environment.

The exposure of electronics to an environment where humidity, temperature, and atmospheric pollutants are not controlled can result in corrosion. The atmospheric pollutants mentioned are H2S, NOx, SOx and chlorides. Among these pollutants, H2S and SO2 acts as the main source if humidity levels are high. The rate of corrosion also depends on the industry and its location. The electronics used in the rubber manufacturing Industry or paper mills can cause failures due to corrosion in just a few weeks.

Silver plated copper lead frames can get corroded easily by the aforementioned gases if any Sewage treatment plant, heavy traffic or open drains are located near it. The concentration of these gases can be as low but still cause significant corrosion. The lead free regulations for electronic equipment has increased the sensitivity of corrosion and failures.

The entrapment of corrosion causing gases in the severe working environment requires specialist help. Being a specialist vendor in gas phase filtration and monitoring AQOZA offers optimum performing corrosion control units to various industries. Get in touch with us to know more!!!

Which Are The Gases Causing Corrosion Of Electronics In Data Centres

Electronic components are made of metallic and non-metallic materials that are prone to corrosion. If left unchecked, electronic corrosion can harm electronic components such as film disks and edge connectors in data centres. Film disks store data, and if corroded the stored information could get lost.  Edge connectors are made of copper or are gold-plated over a copper substrate and are situated on the circuit boards. Corrosion can easily lead to disruption in the connector points and affect data transfer. In the case of control rooms or server rooms all metals are susceptible to corrosion in a similar way.

Corrosion in electronics is mainly caused by Acidic gases. The major ones include:

●        Hydrogen sulphide (H2S)

●        Sulphur and nitrogen oxides (SOX, NOX)

●        Inorganic chlorine compounds (Cl2, ClO2, HCL)

●        Photochemical entities (O3)

Hydrogen sulphide (H2S)

H2S will produce HS- ions which will interact with silver and copper. When HS- ions interact with Silver resulting in the formation of the corrosion product of Ag2S. This process is called sulphidation. Similarly, the corrosion of Copper surfaces happens and the resulting product is CU2S. Sulphidation happens even if the concentration Is <1 ppm.

 Sulphur and Nitrogen Oxides(SOX, NOX)

the influence of NOx on corrosion and degradation of materials is very low;

However, in atmospheres containing SO2 an increase of corrosion and degradation is reported when NO2 is present. The role of NO2 is to catalyse corrosion and degradation processes.

Low RH values favour the reaction of NO2 with adsorbed water, forming nitrous and nitric acids, which are the species that react with copper resulting in an outer film of basic copper nitrite. At high RH, NO2 contributes to the oxidation of SO2, strengthening the production of sulphuric acid, the species that reacts with copper forming copper sulphite and sulphate.

 Inorganic chlorine compounds (Cl2, ClO2, HCL)

Reactivity of chlorine compounds will depend upon the specific gas composition. In the presence of moisture, these gases generate chloride ions which react readily with copper, tin, silver, and iron alloys.

These reactions are significant even when the gases are present at low parts per billion levels. At higher concentrations, many materials are oxidized by exposure to chlorinated gases. Sources of chloride ions, such as bleaching operations, sea water, cooling tower vapours, and cleaning compounds, etc., should be considered when classifying industrial environments.

Photochemical entities (O3)

Ozone is an unstable form of oxygen which is formed from diatomic oxygen by electrical discharge or by solar radiation. In general metals are only slightly susceptible to photochemical effects. However, ozone can function as a catalyst in sulphide and chloride corrosion of metals.

VOC or Volatile organic compounds are emitted in significant quantities from different furniture units coated with paint coating, solvents, varnishes, and waxes. It has been seen that furniture units made from solid wood and wood composites play a significant role in the emission of VOC.

[aqozatechnologies]

VOC Emissions In Furniture & Paint Coating

VOC or Volatile organic compounds are emitted in significant quantities from different furniture units coated with paint coating, solvents, varnishes, and waxes. It has been seen that furniture units made from solid wood and wood composites play a significant role in the emission of VOC.

They have an adverse effect on the human body and are directly related to several health risks. In simple words, VOCs are lipid-soluble compounds that can easily pass through the blood-brain barrier resulting in neurologically adverse health impacts.

While several new technological developments in furniture finishing have resulted in stylish furniture units, it is a real fact that they can lead to indoor air pollution. All designers, producers, and consumers are much concerned about furniture products' aesthetics, cost, durability, and functionality. But the issue regarding chronic VOC exposure from furniture must be addressed.

Mainly solid wood and wood panels are used for manufacturing furniture units. The surface of the furniture is coated with various kinds of finishing that include lacquers, varnishes, resin impregnated papers, along with overlays and high-pressure laminates. Most of these finishes consist of terpenes, aldehydes, and aromatic hydrocarbons.

Know about the adverse health impacts of VOCs:

Various chemicals utilized for wood furniture finishing are phthalates, heavy metals, flame retardants, and VOCs. Phthalate kinds of plasticizers and flame retarding compounds are released from furniture units. A recent study has proven that dimethyl esters of succinic, adipic, and glutaric from some of the wooden furniture coatings were found, and it was thus concluded that they are emerging air pollutants. And also, it has been seen that all these esters result in degenerating the olfactory system that impacts the sense of smell.

It seems that VOCs emitted from furniture units and their possible health impacts on children and adults must be considered for raising awareness and shielding human health. Children are mainly affected and are sensitive because of their weak immune systems.

Let us know how it affects children:

●       It affects their physical and cognitive development.

●       With low body weight and fast breathing, they are affected more by the chemical substances present in the air.

●       In children, the metabolizing capacity is prolonged, for which many chemicals stay in their bodies for a long time.

●       A large number of the chemical can imitate hormones, for which they hurt both the endocrine and developing systems.

So, keeping all these concerns in view, it is essential to control VOC emission by the authorities to protect adult and child health. All these regulations are also suitable for controlling odor present indoors. It is often recommended to ventilate all rooms as one of the primary precautions for decreasing VOC emission. Determination of the emitted VOC substance and the level of emission for various kinds of materials and development of standard methods and techniques for detecting VOC emission and developing a VOC removal system are essential for controlling their effect on human health.

Data centers run round the clock and have a lot of sensitive equipment. The continuous operation generates a lot of heat and the large installation has to be cooled using air cooling systems.

The presence of contaminants in the air is a serious issue faced by data centers globally as poor quality air and pollutants can cause damage to sensitive electronic components

[aqozatechnologies]

In's And Out's Of Air Purification In Data Centers

When lead-free manufacturing regulations or Restrictions on Hazardous substances rules were implemented, data center companies got relief hoping that they would now get the most effective electronic equipment. But with time, they found out that the equipment is at more risk of corrosion because of the low ambient quality of air.

Data centers run round the clock and have a lot of sensitive equipment. The continuous operation generates a lot of heat and the large installation has to be cooled using air cooling systems.

The presence of contaminants in the air is a serious issue faced by data centers globally as poor quality air and pollutants can cause damage to sensitive electronic components

Air contaminants are a real problem in data centers.

Data centers are dynamic places. The server and the cooling system will run for 24 hours, seven days a week. Personnel clean the sites at least once a week, and technicians replace old devices or repair technologies so that all clients can easily maintain access to data whenever needed. These processes can also bring contaminants that put computers in danger and other devices in the facility.

While many locations have clean air, many data centers are present in places where some  particle emissions and other gas contaminants are abundant. Even though the site has good quality air, some contaminants like dust, corrosive gas molecules are present in all kinds of environments.

Some of the common air contaminants of data centers are

●       Concrete dust: When concretes are unsealed, it keeps the potential to emit some of the fine dust into the air. These particles consist of calcium, silica, and others with abrasive properties.

●       Ferrous metal particles: This comes from printers, worn parts in HVAC units, conduit pipes, and several mechanical functions. They can lead to electrical damage to the circuit boards as they are conducive, resulting in data center downtime.

●       Gases causing corrosion: Gaseous contaminants like sulfur dioxide, hydrogen sulfide, nitrogen dioxide, ozone, etc. They are the leading cause of copper and silver corrosion, and they can also cause corrosion of some of the delicate metal parts.

●       Chlorides or salts: Those data centers near coastal areas will have to face airborne salt levels.

●       Electrostatic dust: Dust and the lint particles coming from clothing, paper, and other particles become static charged. Servers lead to faulty commands, data loss, and other such problems.

Data centers keep on running non-stop so that people can easily access a wealth of information. High exposure to contaminants is threatening for data centers which can lead to serious disruptions in the data chain.

Here are a few data center malfunctions because of contaminants:

●       Poor air quality can affect the cooling system.  This means either the cooling system breaks down or more power is needed for generating cooling air for keeping all components functioning.

●       Any salt and sulfur reaching data centers can easily corrode the critical electrical components and lead to electrical shortages, physical deterioration, and discharges.

How to solve the poor air quality issue in data centers?

Executing an efficient air filtration method, which also includes using the right kind of air filters, can assist data centers in keeping up with all changing regulations, decreasing the equipment failure and cost of cooling. It also enhances the health and safety of workers.

Data centers and server rooms require air purification.

The use of air purification methods or air purifiers helps resolve air quality issues. When you use  data center air purifier, the contaminated air passes through the pre-filters that retain all dust and particles. In the chemical media stage, the contaminants are destroyed chemically. Gaseous filtration is one of the efficient methods of removing airborne contaminants for increasing performance.

Conclusion

The excellent air quality of data centers is essential for keeping operations flawless and also ensuring the safety of the workers. Data center air purifier designed for encountering such contaminants are obviously the best and most effective solution for the protection of data, products, and data.

How To Design An Efficient Odour Control Unit?

The odour created from the wastewater system is because of hydrogen sulfide released in the form of gas. Moreover, hydrogen sulfide results in corrosion in collection systems and wastewater treatment plant equipment. Various emission sources also require odour control units like pump stations, sludge dewatering, manhole , etc.

The odour coming from sewage and effluent comprises hydrogen sulfide, and it is pretty dangerous when released in the environment. Odorous gas also consists of ammonia and organic Sulphur components. Even though most odours generally do not cause any physical health issues, mal odour affects the surrounding, leading to complaints to the source.

This source of H2S emission is very much the same as VOCs, with the only difference being the Sulphur compound's presence. odour control units that are safe and efficient assist in solving complicated odour pollution. Their applications are mainly used to remove odour from the sewage treatment plant, sludge, paper &pulp industries, solid waste processing plant, etc. They will cover the foul odours and help you get rid of them efficiently by neutralizing or adsorbing the odour molecule. They are also designed for removing VOC and for meeting hazardous air pollutants along with other regulations.

For designing an efficient odour control unit, it depends on two main parameters:

●            Air volume

●            Air exchange

While calculating the air volume of any process tank, if it is an affixed water level tank, then freeboard air volume should be considered. But when it fluctuates, it is recommended to consider air volume from low water levels.

Air exchange is one of the essential factors to consider while designing the odour control system and one that impacts the size and effectiveness of the odour removal. Many regional municipalities have given guidance on-air exchange factors during the estimation of odour control system capacity.

While considering inlet works, the air exchange factors should be 12-15 times of the air volume. A sludge treatment facility must be 6-12 times of air volume, and it is based on room ventilation, aerated tanks, etc.

Depending on these processes, the engineers can easily assess the  required sufficient capacity of the odour control unit that system manufacturers should verify. To have better clarity, you can also contact an odour control specialist. Look for the best odour control services for ideal odour control management.
