The present invention relates to a treatment method of Fischer-Tropsch synthesis decarbonization tail gas and an equipment system for implementing the method. The method of the invention processes the Fischer-Tropsch synthesis decarbonization tail gas through processes such as CO 2 absorption, extraction and separation, solution regeneration, and tail gas washing, so that the carbon dioxide in the Fischer-Tropsch synthesis decarbonization tail gas can be deeply removed, and purified gas can be produced as a product. Light hydrocarbons, crude naphtha and fuel gas, and waste water by-products. Compared with the traditional process for removing acid gas, the invention has the characteristics of simple process, precise CO 2 removal, cost saving, less loss of hydrocarbons, less loss of cooling capacity and the like. |
