Abstract
Energy is recovered from low calorific value gas by means of a gas turbine. Heat is recovered from the turbine exhaust by indirect heat exchange with water. The resultant hot water is used to saturate the fuel and, optionally, also the combustion air, and/or to aid regeneration of an absorbent used in a wet process to remove carbon dioxide from the gas prior to combustion. Preferably the low calorific value gas is waste gas from a PSA process used to remove impurities in the production of a hydrogen-containing gas stream from a raw gas made by primary/secondary steam reforming a hydrocarbon feedstock at superatmospheric pressure and the turbine drives the secondary reformer air compressor.
