N-甲基二乙醇胺-二乙醇胺复合溶液脱除采出气中的CO2
Removal of CO2 from Produced Gas Using N-methyldiethanolamine-diethanolamine Complex Solution
摘要
Abstract
Considering the field condition of CO2-EOR(enhanced oil recovery) blocks in Shengli oilfield, the produced gas containing CO2 was simulated in a pressure device. The effects of Ar-methyldiethanolamine(MDEA) solution and Af-methyldiethanolamine-diethanolamine(MDEA-DEA) complex solution on removal of CO2 from the simulated produced gas were studied under moderate pressure, and the experiment on regeneration of saturated absorption liquid was carried out. Under the conditions of V(CH4) : K(CO2)=3 : 7, reaction temperature 70.0 ℃, reaction pressure 0.5 MPa, mass fraction of MDEA in MDEA-DEA complex solution 40% and mass fraction of DEA in MDEA-DEA complex solution 2%, the absorption volume of CO2 is 48.429 71 L, the regeneration temperature is 106.0 ℃, the regeneration energy cost is 0.010 12 kW o h/L, the regeneration efficiency is 98.84%.关键词
