Recently, the overseas second set 84,000 air separation project of HANGZHOU FORTUNE GAS CRYOGENIC GROUP successfully ran to production. This is another phased achievement after the successful production of the project in 2021.

The first set of 84,000 air separation device was reached during the epidemic period, FORTUNE bravely took the heavy burden and moved forward in the reverse direction to help Belt and Road connect the world.

According to the introduction, this project is the second set of the largest "Belt and Road" air divide EPC project (3 sets of 84,000 air divide) in China's deep cold industry, marking that FORTUNE has made another important breakthrough in the deep cold industry, "German quality and Zhejiang enterprise style" to the world and toward a higher level.

FORTUNE said that our people responded to customer needs, in order to ensure the operation of the device, due diligence adhere to the front line, from every detail began to care for customers, fully demonstrated the "180 striver spirit". I believe that in the future, the wish of the talent-"blessing to the world" can be realized, and the process of hard work will build the most beautiful scenery in memory.

Recently,The first phase special gas construction of Tongling Zhengfan Electronic Materials Company is stepping up the construction at the eastern park of Tongling Economic development zone.

It is said that Tongling Zhengfan is a wholly-owned subsidiary of Zhengfan Technology(The Science and Technology Innovation Board). It mainly carries the core business of Zhengfan technology in electronic gas and electronic materials. After the completion, the annual production capacity of 90 tons per year of hydrogen phosphide gas can be formed. At present, the project has entered the equipment installation stage, and it is expected to be in trial production by the end of this year.

First set of skid-mounted CCUS-EOR circulating gas injection device

【Gas Ecosphere(www.igascn.com)】

Recently, we learned from the CCUS-EOR demonstration area of Dagang Oilfield that the first set of skid-mounted fully intelligent CCUS-EOR cycle gas injection device in China made the first show in well hole 104-1, injecting 110,000 cubic meters of carbon dioxide and recycling 133 tons of carbon dioxide, truly achieving zero carbon emissions. This move also marks a new technological breakthrough in the whole industry chain of CCUS-EOR, which is called "carbon utilization, extraction rate, carbon cycle and carbon storage".

Recently, we learned from the CCUS-EOR demonstration area of Dagang Oilfield that the first set of skid-mounted fully intelligent CCUS-EOR cycle gas injection device in China made the first show in well hole 104-1, injecting 110,000 cubic meters of carbon dioxide and recycling 133 tons of carbon dioxide, truly achieving zero carbon emissions. This move also marks a new technological breakthrough in the whole industry chain of CCUS-EOR, which is called "carbon utilization, extraction rate, carbon cycle and carbon storage".

Researchers said the device is widely used, which can be flexible layout in carbon dioxide fracturing gas, single well output jet, separation gas production system back back a variety of scenarios, dagang oilfield thus formed the CCUS-EOR industry chain medium full phase injection technology, output gas recovery and recycling technology, carbon dioxide throughput and fracturing as the main body of production technology, the whole process slow release scale resistance technology four characteristic technology, laid the technical foundation to promote the green development.

In order to solve the problem of increasing production and increasing efficiency in extremely high water content and heavy oil reservoirs, Dagang Oilfield has vigorously implemented CCUS-EOR technology since 2018. As the main implementation department, the researchers of Tongxin Bingang Petroleum Science and Technology Group are committed to tackling the problem, and have formed 18 sets of gas drive equipment and more than 10 patented technologies with specialized, fine, special and new characteristics, with an annual carbon dioxide injection capacity of 360,000 tons. According to statistics, in the past five years, 370 Wells, 160,000 tons of carbon injection, 280,000 tons of oil increase and 1.9 million cubic meters of water saving are implemented. The comprehensive oil exchange rate is 1:1.77, and the effect of oil increase and precipitation increase is outstanding.

With the large-scale implementation of carbon dioxide flooding technology, some of the gas not absorbed by the formation is released to the ground with well production. Due to the serious heterogeneity of strata in Dagang oilfield and the dispersion of measure blocks, the scattered gas recovery is faced with the reality of unstable gas source, high operating cost, no mature experience or technology for reference, so it is difficult to build a station to solve this problem. To this end, the researchers devoted themselves to research, after nearly a year of research and development, successfully developed a skid-mounted fully intelligent CCUS-EOR circulating gas injection device.

The device was first used in well hole 104-1 in CCUS-EOR demonstration area. According to the automatic purification of the gas source, the operating state was adjusted, which solved the problem of difficult recycling of scattered gas at one stroke. In the case of unattended site, the Internet of Things is used to implement remote interactive monitoring, and the emergency state can be automatically stopped. Due to the low operating costs, the 14 carbon dioxide swallowing Wells will also be injected back into the formation through this device, with an annual back injection capacity of 3.3 million cubic meters.
