Detect boiler leaks upstream of the shift reactor in H2 plants

摘要

In a typical hydrogen (H2) flowsheet, water gas shift (WGS) reactors are normally located after the steam reforming section. Common products of steam reforming include carbon monoxide (CO), which the WGS reaction converts to produce additional H2, as shown in Eqs. 1 and 2, making WGS reactors important for increased H, production: CO + H2O = CO2 + H2; △H = -41.1kJ/mol (1) The reaction is exothermic, and high conversions are favored by low temperature and high steam-to-dry-gas ratio.
