The attainment of high-purity hydrogen, reaching levels up to 99.9999%, constitutes an imperative requirement across diverse industries. With the support of our esteemed European partners, who boast a portfolio of over 80 successfully commissioned hydrogen production facilities globally, we stand in a formidable position to offer bespoke, economical, and validated solutions for the establishment of hydrogen generation plants that cater to a range of hydrocarbon feedstocks, including natural gas, LPG, naphtha, and methanol.

Our advanced production process for high purity hydrogen involves the steam reforming of hydrocarbons, followed by a PSA purification step. The feedstock is preheated by mixing it with a split stream of hydrogen and passing it through a sulfur removal process. It is then combined with superheated steam and passed through catalyst-filled reformer tubes, where it is converted into a syngas containing H2, CO, CO2, H2O, and CH4.

The hot syngas is then cooled through a heat exchanger, which recovers a significant amount of its sensible heat, before being passed through the CO-shift stage. The syngas is further cooled to ambient temperatures, resulting in the condensation and subsequent separation of water vapor. Finally, the purified hydrogen is isolated to the desired level of purity using a molecular sieve PSA purification unit.

The reformer is fired by a high-velocity burner that consumes both fuel and tail gas. Any tail gas produced during the PSA purification stage is buffered in the tail gas buffer tank. The hot flue gases generated by the reformer are directed towards a waste heat boiler, which is used to superheat the feed/steam mixture and preheat the feed in the heat exchangers.
