Methanol synthesis recovery unit that exits that speeds

The utility model discloses a methanol synthesis recovery unit that exits that speeds, including benzene hydrogenation ware, the institute hydrogenation ware through the pipeline with speed to exit unloading governing valve intercommunication, the inlet piping of pipeline and pressure swing adsorption ware is connected, has two branch pipes on the outlet header of pressure swing adsorption ware, one of them branch pipe and benzene hydrogenation ware intercommunication, and another branch pipe is connected with the hydrogenation synthesis tower, speed to exit the blow -down pipe through the gas pipeline with be used for the speed buffer tank intercommunication of gassing of storage, be equipped with the manometer on the gas pipeline and adjust the pressure regulating valve of transfer press, the buffer tank lets in gas boiler's air inlet through the gas pipeline. The utility model discloses a pipe -line layout and optimization are used for refined crude benzol with the gassing of speeding that produces in the methyl alcohol production process, burn in also can letting in simultaneously the burning boiler, utilize the pluralism of mode, the comprehensive utilization of the gassing that is favorable to speeding for the economic value who produces is higher.
