초록

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/se...

청구항

A process for the recovery of energy by the production of shaft power from a fuel gas comprising: carbon dioxide; and at least one combustible gas selected from: methane; hydrogen; and carbon monoxide; said fuel gas having a composition such that its calorific value is below 1100 BTU/scf (41 MJ.m-3) and containing at least 20% by volume of carbon dioxide; said process comprising: (a) contacting said gas with an aqueous solution of an absorbent for carbon dioxide, whereby carbon dioxide is absorbed from said gas into said absorbent solution and the result...
