Abstract

A facility comprising integrated systems for the extraction, and optionally upgrading and / or refinement, of unconventional oil sources, using fossil fuels as a primary source of energy. In particular, this facility provides a means to gasify one or more fossil fuels in an efficient manner, converting it into intermediate products such as heat, steam and electricity, which are then used by the system to obtain useful fuel products from unconventional oil sources such as tar sands and oil shale. The design of the components of this facility is optimized such that the overall costs are competitive with an equivalent unconventional oil source processing facility that uses natural gas as a source of processing energy. The facility can be used on its own, may use supplemental natural gas energy sources, or may be used in conjunction with an existing facility that uses natural gas as an energy source in order to improve the overall cost effectiveness of the processing and / or reduce the requirement for other energy sources, such as natural gas.

Plasma Gasification System Integrated with an IGCC

[0698]This example describes a plasma Gasification System integrated with an IGCC. The plasma Gasification System comprises a converter, solid residue conditioner, a GCS, and a gas storage or regulation system, integrated with use of a combined-cycle to produce electricity.

[0699]As shown in FIG. 119, coal 106 is combined with oxygen from an oxygen plant 105 in the converter 100 to produce syngas, which is mainly hydrogen and carbon monoxide. The syngas is then cooled in a heat recovery steam generator (HRSG) 120 and then cleaned by a gas cleanup process in a GCS which includes the steps of scrubbing the syngas in a scrubber 130, removing particulate matter and heavy metals from the syngas in a baghouse 140, and H2S removal in an H2S removal system 150. The cleaned or conditioned gas is then stored or regulated in a gas storage or regulation system 160 prior to being fed to a gas turbine 170 for the production of electricity.
