Hydrogen Plant

Hydrogen generating units are an integral part of any refinery or nitrogeneous fertiliser plant. Hydrogen gas is generated by the reforming route where a hydrocarbon is converted to hydrogen rich stock that is used for hydrogenation of oil or for manufacturing of methanol, ammonia or synthesis gas (used for nitrogeneous fertilisers).

The gases leaving the reformer need to be cooled before going to the converter. A fire-tube waste heat boiler is provided to cool the process gases coming from the reformer, also known as Process Gas Boilers (PGB). The flue gases leaving the reformer are also a potential source of waste heat and this is also harnessed though water tube or fire tube type of heat recovery boilers and are also integrated to superheat steam as well as preheat the feed stock.
