Process

Technological process

After pressurized desulfurization, natural gas or other raw materials are mixed with water steam and enter the special reformer. Under the action of catalyst, the reformer reacts to produce the reformer gas containing H2, CO2, CO and other components. After the heat of the reformer gas is recovered, CO is converted into hydrogen by the shift reaction. The shift gas is purified by PSA to obtain hydrogen. The PSA tail gas returns to the reformer for combustion and heat recovery.
