Extracting measures

摘要

A new environmentally friendly treatment for liquid carbon dioxide (CO_2) could improve the efficiency of using the chemical compound to extract oil from the ground.rnScientists at Bristol University have developed the soap-like hydrocarbon additive as a way of thickening liquid CO_2 so it can be used to increase oil production by effectively flushing oil out of the pores of rocks,rnThe chemical additive (TC14) is the first known substance that turns liquid CO_2 into a viable solvent for enhanced oil recovery (EOR) but does not contain fluorine. Liquid CO_2 requires less processing than other petrochemical solvents and can be easily recycled.
