Device for absorbing methanol in mercaptan by using synthetic wastewater

The utility model discloses a device for absorbing methanol in mercaptan by using synthetic wastewater, which relates to the technical field of chemical engineering, comprises an absorption tower, an absorption tower feeding heat exchanger and an absorption tower discharging pump, and solves the problem that in the original process, condensed mixture enters the absorption tower, deionized water is added into the absorption tower for liquid-liquid absorption, and the methanol in the mercaptan is absorbed by the absorption tower. In order to solve the problems of low mass transfer efficiency, high requirement on equipment and high energy consumption in the prior art, the device disclosed by the utility model has the advantages that the synthesis gas firstly passes through the absorption tower and then is subjected to multi-stage condensation, and the synthesis gas entering the absorption tower is in contact with water to be cooled, so that the energy consumption of multi-stage condensation is saved, methanol in
