[Ten years of development of chemical equipment] 1034-2023 my country has realized long-distance dense phase pipeline transportation of liquid carbon dioxide for the first time

Thread Content

Chemical science and technology has developed greatly in the past ten years, praising the prosperity of China in the prosperous world. It is more lively and more exciting with everyone's participation. Everyone is welcome to participate in the forum to exchange and discuss. July fires, pay attention to fire prevention-------------------------------------------------On July 11, 2023, my country's first high-pressure normal temperature dense phase carbon dioxide transmission pipeline project with a million-ton transmission scale, a hundred-kilometer transmission distance, and a hundred-kilogram transmission pressure - a total length of 109 kilometers.“* * * * -Shengli Oilfield's "Million-ton CCUS Project" carbon dioxide transmission pipeline was officially put into operation, which is a milestone in promoting the large-scale development of my country's CCUS (carbon dioxide capture, utilization and storage) entire industry chain. For the first time, my country has realized long-distance dense phase pipeline transportation of liquid carbon dioxide. The dense phase refers to a state of carbon dioxide at conditions above the critical pressure and below the critical temperature, that is, the operating pressure is higher than 7.38 MPa and the operating temperature is lower than 31.1 degrees Celsius. The pipeline can transport 1.7 million tons per year * * * * The carbon dioxide captured during production is transported to the underground reservoir of Shengli Oilfield for oil displacement and storage.“ * * * * -An important part of Shengli Oilfield’s million-ton CCUS project.
