EQUIPMENT FOR PRESSURIZED ADSORPTION AND LIQUIFICATION OF CARBON DIOXIDE FROM BOILER FLUE GAS FOR OIL RECOVERY BY WELL INJECTION

摘要

An equipment for the pressurized adsorption and liquification of carbon dioxide from boiler flue gas for oil recovery by well injection comprising boiler for generating high pressure steam 1, high pressure water pump 2, tower scrubber 3, compressor 4, absorber 5, separation tank 6, flash pot 7, solvent pump 8, stripper 9, air pump 10, carbon dioxide compressor 11, purifier 12, liquefier 13, congealer 14, rectifying tower 15, condenser 16, storage tank 17, drying beds 18, membrane module 19, nitrogen pressurizer 20, carbon dioxide pump 21 and mixing tank 22. ;With rational design and handsome practicability, the comprehensive mate equipment, when producing steam by the boiler, can obtain carbon dioxide liquid and nitrogen, thus realizing “single injection”, “double injection” or “triple injection” of steam, gaseous carbon dioxide and nitrogen and thereby gaining favorable results of crude oil output increase as well as environment protection.
