Abstract
A process for producing energy from sulphur containing carbonaceous fuels comprises partially oxidizing the carbonaceous fuel to produce off gasses including carbon monoxide, hydrogen and hydrogen sulphide; removing hydrogen sulphide from the off gasses and combusting the off gasses from which the hydrogen sulphide has been removed to produce energy.
Claims24
A process for producing energy from sulphur containing carbonaceous fuels comprising the steps of:
- (a) partially oxidizing the carbonaceous fuel at a pressure from about 10 to about 40 bars and a temperature from about 1,200.degree. C. to about 1,700.degree. C. to produce off gasses including carbon monoxide, hydrogen and hydrogen sulphide;
- (b) removing hydrogen sulphide from said off gasses;
- and,
- (c) combusting the off gasses from step (b) to produce energy.

A process for producing energy from a carbonaceous fuel containing at least about 0.5% sulphur by weight, said process comprising the steps of:
- (a) introducing said carbonaceous fuel and oxygen into a partial oxidation reactor;
- (b) subjecting said carbonaceous fuel to partial oxidization at a pressure from about 10 to about 40 bars and a temperature from about 1,200.degree. C. to about 1,700.degree. C. to produce a carbon monoxide, hydrogen and hydrogen sulphide rich off gas stream;
- (c) removing hydrogen sulphide from said off gas stream to produce a hydrogen sulphide deficient stream;
- and,
- (d) combusting said hydrogen sulphide deficient stream to produce energy.
