Embodiment Construction

[0016] One or more specific embodiments of the invention are described below. In an effort to provide a concise description of these Examples, all features of an actual implementation may not be described in the specification. It should be understood that in the development of any such actual implementation, as with any engineering or design effort, many implementation-specific decisions must be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints , which may vary by implementation. Furthermore, it should be appreciated that such a development effort might be complex and time consuming, but would be no more than a routine of design, fabrication, and fabrication for those having the benefit of this disclosure.

[0017] When introducing elements of various embodiments of the invention, the articles "a," "an," "the," and "said" mean that there are one or more of the elements. The terms "comprising", "including" ...

Abstract

A system comprising a multi-stage reactor. The multi-stage reactor may include a water gas shift (WGS) reactor and a sour methanation reactor configured to generate methane without prior removal of acid gas. Furthermore, the multistage reactor may be a single unit having both the WGS reactor and the methanation reactor.

Description

technical field [0001] The subject matter disclosed herein relates to the production of alternative natural gas. Background technique [0002] In general, integrated gasification combined cycle (IGCC) power plants are capable of relatively clean and efficient energy generation from various hydrocarbon feedstocks, such as coal. IGCC technology converts hydrocarbon feedstocks into carbon monoxide (CO) and hydrogen (H 2 ), that is, synthesis gas. These gases can be cleaned, treated and used as fuel in conventional combined cycle power plants. For example, syngas may be delivered to the combustor of a gas turbine of an IGCC power plant and ignited to drive the gas turbine for power generation. [0003] However, the syngas can be further converted to substitute natural gas (SNG), which can be fed into the combustors of the gas turbines of new or existing (retrofitted) natural gas combined cycle (NGCC) power plants and ignited to drive the gas The turbines are used for power g...
