Systems and methods for producing synthetic gas are provided. The method can include gasifying a feedstock within a gasifier to provide a raw syngas. The raw syngas can be processed within a purification system to provide a treated syngas, and the purification system can include a flash gas separator. The treated syngas and a first heat transfer medium can be converted into a synthetic gas, a second heat transfer medium, and a methanation condensate. The methanation condensate can be introduced to the flash gas separator.

Systems and methods for producing substitute natural gas

Systems and methods for processing a hydrocarbon are provided. The method can include gasifying a feedstock within a gasifier to provide a raw syngas. The raw syngas can be processed within a purification system to provide a treated syngas. A first portion of the treated syngas can be converted into a first effluent in a first methanator. The first effluent can be mixed with a second portion of the treated syngas to provide a first mixed effluent. The first mixed effluent can be converted into a second effluent in a second methanator. The second effluent can be mixed with a third portion of the treated syngas to provide a second mixed effluent. The second mixed effluent can be converted into a third effluent in a third methanator.

Systems and methods for producing synthetic natural gas are provided. The method can include gasifying a carbonaceous feedstock within a gasifier to provide a raw syngas. The raw syngas can be cooled to provide a cooled raw syngas. The cooled raw syngas can be processed in a purification system to provide treated syngas. The purification system can include a flash gas separator in fluid communication with the gasifier and a saturator. The treated syngas can be converted to synthetic natural gas to provide steam, a methanation condensate, and a synthetic natural gas. The methanation condensate can be introduced to the flash gas separator.

A process for producing electrical power, chemicals, carbon dioxide, and hydrogen is provided. One or more feedstocks and one or more oxidants can be combined in a fluidized reaction zone heated to a temperature from about 1050&#xb0; F. to about 1900&#xb0; F. to provide a synthesis gas comprising carbon dioxide, carbon monoxide and hydrogen. In one or more embodiments, at least a portion of the synthesis gas can be used as a fuel source for one or more turbines to drive one or more electrical generators. In one or more embodiments, at least a portion of the synthesis gas can be introduced to one or more gas converters to provide methanol, alkyl formates, dimethyl ether, ammonia, Fischer-Tropsch products, derivatives thereof or combinations thereof.
