Methanol Reforming
With the HM process, high purity hydrogen is produced by methanol reforming combined with a PSA purification step.
A mixture of methanol and demineralised water is vaporised in heat exchangers by hot syngas leaving the reformer and circulated inert gas heated by a high velocity burner. Whilst passing the catalyst, the methanol/water vapour mixture is converted into a syngas consisting of H2, CO, CO2, CH4 and watervapour. In a cooler, the syngas is cooled to ambient temperatures, whilst simultaneously water vapour is condensed and recycled to the storage tank. The syngas now passes the molecular sieve PSA purification unit where the H2 is isolated to the specified purity. The tail gas from the PSA purification unit is sent to the buffer tank. From the buffer tank, the tail gas is used as fuel for the high
velocity burner.
Using inert gas instead of thermal oil as heat transfer fluid for heating the reformer makes a hot oil system obsolete and avoids all costs and problems of handling hot oil.
