ZHAO CONG/FOR CHINA DAILY In order to construct the carbon storage facility, employees from Liaohe Oilfield collaborated with dozens of experts and professors from several universities, including Dalian University of Technology. Once the injected carbon dioxide encounters water in the formation, it will generate acidic liquid, and the acidity is directly proportional to the mineralization of the water. Wang explained that the cyclic injection station includes important components such as the hydrocarbon removal unit, carbon dioxide pressure swing adsorption unit, and pressurized dehydration unit. Currently, three carbon capture facilities and one cyclic injection facility have been completed and put into operation at the CCUS cyclic injection station, with a maximum daily processing capacity of 240,000 cubic meters, possessing an annual carbon capture capacity of 137,000 tons and an injection capacity of 208,200 tons.
