Purge Gas Hydrogen Recovery Technology
This technology adopts an advanced pressure swing adsorption (PSA) gas separation unit to efficiently purify the purge gas delivered from the ammonia washing recovery post of the synthesis workshop. Through a series of sophisticated process steps, the hydrogen purity in the gas is raised to over 95%. The recovered product hydrogen is sent to the inlet main pipe of the first stage of the compressor for subsequent production; the desorbed gas is fed into the boiler water seal tank and then into the combustion chamber of the gas-fired boiler, realizing energy recycling and greatly improving the resource circulation utilization rate.
■ Technical Features
