• Safe and practical operation control with a high degree of automation.
• Low operating costs and short payback period.
• Off-gas of PSA recovered as fuel reduces both fuel consumption and exhaust emissions.
• Pre-fabrication skid 
• Pre-fabricated top-fired cylinder reformer saving huge on-site installation work

Process Schematic

Process Description

Desulphurization gas is mixed with steam as per a certain ratio. The mixutre flows through the Reformer Tubes, where it converts into the syngas consisting of hydrogen and carbon monoxide and carbon dioxide and unreacted methane and steam in the presence of catalysts.

A heat exchange system is used as an economizer, while a shift converter is introduced to convert carbon monoixed into extra hydrogen and carbon dioxide. The resulting gas enters into a PSA unit, where the hydrogen is separated from the other gases. The off-gas of PSA is recovered as fuel.

Reaction Formula
