Used 70 MMSCFD hydrogen plant, (2) trains with 95% purity. Technology provided by Foster Wheeler. The two trains share a natural gas feed system which includes two feed compressors, one recycle compressor, a feed pre-heater furnace, and a hydro-desulfurizer vessel. The Hydrogen Production Trains are nearly identical and are completely independent downstream of the common feed system. 1,200 mt/day of food grade carbon dioxide (CO2) was also produced from the plant. Each train was originally designed to produce 70.0 MMCFD hydrogen, capacity can be increased to rates of 90 MMCFD due to improved operating procedures and the de-bottlenecking of plant equipment. Low turndown – the entire complex can be run at 40 MMSCFD of hydrogen (one train down and one running at 40% capacity). Hydrogen purity improved up to 99% when running at low capacity. Honeywell Experion DCS process control system available with software and backed up database. Plant built in 1966 and shut down in 2018. Plant had major upgrades during the time, last upgrade in 2016. New radiant section tubes, Incoloy outlet pigtails and Incoloy outlet collection headers installed recently in both A-train and B-train. With conservative reformer temperatures, the tubes could have over 10 years of life. The A-Train reformer has a selective catalytic reduction (SCR) system with upgraded honeycomb catalyst for controlling reformer burner emissions while the B-Train reformer uses Low-NOx burners to accomplish the same. The plant originally ran with naphtha feed to the reformer, necessary additional equipment still in the plant. All documents are available.
