Title:
TAIL GAS RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/131052
Kind Code:
A1
Abstract:
The present application relates to the technical field of tail gas recovery, and provides a tail gas recovery system. The tail gas recovery system comprises a pressurization member for pressurizing the tail gas of a carbon hydrocarbon gas thermal cracking reaction, a long-chain carbon hydrocarbon removal member for removing long-chain carbon hydrocarbon in the tail gas, a conversion member for converting unsaturated carbon hydrocarbon in the tail gas into saturated carbon hydrocarbon, and a first liquefaction and recovery member for liquefying and recovering methane in the tail gas; the pressurization member, the long-chain carbon hydrocarbon removal member, the conversion member, and the first liquefaction and recovery member are sequentially connected; and the tail gas of the carbon hydrocarbon gas thermal cracking reaction sequentially passes through the pressurization member, the long-chain carbon hydrocarbon removal member, the conversion member, and the first liquefaction and recovery member. Tail gas recovery treatment is performed in a gas-liquid separation mode, and methane having a large proportion in the tail gas is liquefied and recovered; the tail gas recovery system is simple in structure and simple in recovery process, so that environmental pollution is reduced, methane can be applied to a subsequent carbon hydrocarbon gas thermal cracking reaction, and the production cost can be greatly reduced.
