Embodiment Construction

[0012]One or more specific embodiments of the present invention will be described below. In an effort to provide a concise description of these embodiments, all features of an actual implementation may not be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0013]When introducing elements of various embodiments of the present invention, the articles “a,”“an,”“the,” and “said” are intended to mean that ther...

Abstract

Systems for efficiently compressing a gas are included. In one embodiment, a system includes a carbonous gas compression system and a vapor absorption chiller (VAC). The carbonous gas compression system comprises a compressor configured to compress the carbonous gas. The VAC is configured to circulate a coolant through at least one coolant path through the carbonous gas compression system. Utilization of the VAC may aid in cooling the carbonous gas, which may allow for less energy to be expended by the compression system.

Description

BACKGROUND OF THE INVENTION[0001]The subject matter disclosed herein relates to systems for efficiently compressing a gas, such as carbon dioxide (CO2), in a power plant such as an integrated coal gasification combined cycle (IGCC) or a coal-fired conventional power plant.[0002]Power plants, for example IGCC power plants, may produce a carbonous gas such as CO2. In IGCC power plants, a syngas is created by gasifying a carbonaceous fuel such as coal. The syngas may be utilized as fuel for power generation. The syngas may be fed into a combustor of a gas turbine of the IGCC power plant and ignited to power the gas turbine, which may then drive a load such as an electrical generator. One byproduct of such plants may be CO2. Carbon capture and sequestration is very likely to be a key element of any future greenhouse gas legislation, such as CO2 legislation. Thus, power plants may be under provisions to separate the CO2, either pre-combustion or post combustion. The CO2 may be captured, ...
