The device comprises a regeneration tower main body, a solution boiler at the bottom, as well as a regenerated gas cooler and regenerated gas separator arranged at the top. The operation difficulty of the device is reduced, the protection of technology secrete is facilitated, and meanwhile the device is compact to be beneficial toskidding. The operation procedure is simplified, and meanwhile the structure is compact to be beneficial to miniaturization of equipment and implementation of skidding effect.

Description

technical field [0001] The invention belongs to the technical field of gas purification, and proposes a device and a regeneration process for decarburization, heating, regeneration, condensation, and separation in a hot potash-alkali method. Background technique [0002] The Fischer-Tropsch synthesis process uses coal or natural gas as the raw material to indirectly synthesize liquid fuels. In the Fischer-Tropsch reaction, while H2 and CO generate hydrocarbon products on the reduced catalyst, water is simultaneously generated during the reaction process, and water and CO undergo water gas A large amount of CO is produced by shifting the reaction 2 . Therefore, after the product is separated from the gas out of the synthesis reactor, the remaining tail gas must be freed of CO before being recycled. 2 . Due to the use of hot potash method for CO removal 2 Its hydrocarbon loss is minimal, so Fischer-Tropsch synthesis cycle gas decarburization is commonly used in this method...
