Optimization of carbon dioxide capture and liquefaction technology for Changqing gasfield purification plant
Reducing carbon dioxide emissions is an important means of controlling carbon emissions,and the carbon dioxide captured by gasfield purification plants can be used in fields such as carbon dioxide oil recovery.In response to the actual situation of the Changqing gasfield purification plant needing to carry out tail gas capture and recovery of carbon dioxide,this paper explores the feasibility of capturing carbon dioxide in the purifi-cation plant,and proposes a positive pressure incineration and sodium hydroxide alkali wash-ing tail gas treatment process,as well as a carbon dioxide capture and liquefaction process of amine liquid capture and propane refrigeration.At the same time,the carbon dioxide recov-ery rates and energy consumption of each purification plant in Changqing gasfield are ob-tained.It is of great significance for the next step of carbon dioxide recovery.
