Comprehensive utilization of by-product hydrogen recovered from ion-exchange membrane electrolysis
By-product hydrogen is pressurized by a compressor and then undergoes impurity removal treat-ment.It then enters a pressure swing adsorption device for purification to produce high-purity hydrogen.A portion of the obtained high-purity hydrogen is sent to a hydrogen refueling master station for sale,and a portion is reused in the ethylene glycol device.This project effectively improves the utilization rate of hydro-gen,reduces the safety risk of the device,and simultaneously reduces the load of the front-end coal-to-hydrogen production process.It reduces production consumption,achieves the goal of energy conservation and carbon reduction,and improves the economic benefits of enterprises.It also provides a reference for the comprehensive utilization of hydrogen in the same industry.
