Abstract
Systems and methods for gasifying a hydrocarbon feedstock are provided. The hydrocarbon feedstock can be gasified in the presence of one or more particulates to produce a syngas and one or more carbon-containing particulates. At least a portion of the carbon of the one or more carbon-containing particulates can be combusted in a combustion process external to the gasifying of the hydrocarbon feedstock to produce a combustion gas. The combustion gas can be utilized in one or more processes external to the gasifying of the hydrocarbon feedstock.
Claims20
A method for gasifying a hydrocarbon feedstock, comprising:
- gasifying a hydrocarbon feedstock in the presence of one or more particulates to produce a syngas and one or more carbon-containing particulates;
- combusting at least a portion of the carbon of the one or more carbon-containing particulates in a combustion process external to the gasifying of the hydrocarbon feedstock to produce a combustion gas;
- and
- utilizing the combustion gas in one or more processes external to the gasifying of the hydrocarbon feedstock.
A method for gasifying a hydrocarbon feedstock, comprising:
- gasifying a hydrocarbon feedstock in the presence of one or more particulates to produce a syngas and one or more carbon-containing particulates;
- combusting at least a portion of the carbon of the one or more carbon-containing particulates in a combustion process external to the gasifying of the hydrocarbon feedstock to produce a combustion gas;
- and
- utilizing the combustion gas in one or more processes external to the gasifying of the hydrocarbon feedstock,
- wherein the one or more carbon-containing particulates comprise carbon-containing coarse ash, carbon-containing fine ash, or a combination thereof, and wherein the one or more processes external to the gasifying of the hydrocarbon feedstock comprise:
- heating a boiler feed water;
- heating at least a portion of the syngas;
- heating a first oxidant;
- heating a steam;
- drying a moisture-containing hydrocarbon feedstock;
- or a combination thereof.
An apparatus for gasifying a hydrocarbon feedstock, comprising:
- a gasifier;
- a combustor, wherein the combustor is external relative to the gasifier;
- a carbon-containing particulate line in fluid communication with the gasifier and the combustor;
- and
- one or more lines in fluid communication with the combustor and one or more processes external to the gasifier.
