Abstract
Chlorine and sulfur-free fuel gas substantially comprising H.sub.2 +CO for use as fuel in a gas turbine for the production of mechanical and electrical power and environmentally-safe flue gas is produced by the partial oxidation of liquid hydrocarbonaceous or solid carbonaceous fuels having chlorine and sulfur-containing impurities, cooling and splitting the raw fuel gas into two streams A and B, separately cooling raw fuel gas stream A by indirect heat exchange with dry N.sub.2 gas while separately cooling the stream of raw fuel gas B by indirect heat exchange with the product stream of clean chlorine and sulfur-free fuel gas. HCl and particulate matter are then removed from raw fuel gas streams A and B; and, after combining raw fuel gas streams A and B together further cooling and removal of sulfur-containing gases takes place. By this process, attack on metal heat exchangers by the corrosive constituents in the raw fuel gas is prevented. In one embodiment, the clean chlorine and sulfur-free fuel gas is humidified and burned in the gas turbine to produce increased power and efficiency without polluting the atmosphere.
