Produce hydrogen (H2) in the capacity range of 100–1,000 Nm3/h of H2 for usage by the chemical industry and the manufacture of electronics.
Feed methanol and water are mixed, evaporated and superheated before being sent to the methanol decomposition reactor. In this reactor, the methanol is reacted to form H2, CO and CO2. The reaction is endothermic and requires energy by heat transfer from externally heated oil or by steam. The raw gas from the reactor is cooled, and the process condensate is separated. The separated gas is further purified by a pressure swing adsorption (PSA) unit; startup, operation and shutdown are automatic.
Features: Utility requirements per Nm3 of H2 are:
Methanol, kg 0.63
Fuel, kcal 320
Demineralized water, kg 0.37
Electricity, kWh 0.06
Additional utilities required Cooling water, instrument air and nitrogen The hydrogen plant construction is compact and can be skid-mounted.
Economics: Features include:
• Low investment cost
• Low operating costs
• Low maintenance cost
• Short delivery time
• Fast installation of the skid-mounted unit.
