This device uses molecular sieve membranes for continuous dehydration of tetrahydrofuran. The annual processing capacity is 22,400 tons, the raw material water content is 6%, and the product water content is less than 1%. Water content tetrahydrofuran. The device was commissioned in March 2020 and successfully operated. After the treatment of the device, the water content of the tetrahydrofuran product meets the requirements, the equipment operates continuously and stably, and the membrane separation-rectification coupling system produces qualified tetrahydrofuran products with a water content of less than 200 ppm. This is a successful case of molecular sieve membrane used in the coupling dehydration of tetrahydrofuran solvent in the field of fine chemicals.
