Blue hydrogen: Partial Oxidation hydrogen Partial Oxidation (POX) is a process for generating syngas and oxogas through the partial oxidation of a hydrocarbon feed
This produces a mixture of hydrogen, CO and CO2. The reformed gas is then cooled down, generating high- pressure steam, and the CO2 is removed in an amine wash unit. The hydrogen / CO syngas product ratio can be modified according to customer’s needs by using a membrane, Pressure Swing Adsorption unit or a CO Cold Box. The same steps may be also used to generate pure CO and / or hydrogen as products.
such as natural gas in a refractory-lined reactor.
The feed gas is initially mixed with steam and pre-heated in a fired heater. Oxygen, feed and steam are then fed via a proprietary burner to a refractory- lined reactor operating at 40 to 100 barg. This process causes the partial oxidation of the feed gas.
