• The hydrogen plant was only installed in 2007 and is based on Foster Wheeler technology. The plant produces 25,000 Nm³/hr of 99.99% pure H2. The Plant was shutdown in 2011.
• The H2 from the PSA plant is partially recycled to mix with the methane feed with the rest sent to the site H2 system at 99.99%.
• The exit temperature from the shift reactor is 412°C. The H2and CO2 passes through a series of shell and tube steam generators, heat exchangers and an air fin fan cooler which drops the gas temperature down to 60°C. Any remaining water is separated in the cold condensate drum which is then heated to feed the deaerator. Heat exchangers are stainless steel.
• Expected documentation was observed during the inspection, such as PFDs, P&IDs, procedures, and equipment files.
