Rectisol Process an overview ScienceDirect Topics

Process Description and Operation. The Rectisol process is available in a wide variety of configurations to meet specific requirements and feed conditions. Systems can be designed to (1) remove all impurities, produring a treated gas that is essentially free of both CO 2 and sulfur compounds; (2)

RECTISOL® wash Linde Engineering

RECTISOL ® is therefore frequently used to purify shifted, partially shifted or unshifted gas downstream residue oil-, coal- or lignite gasification. Due to the low operation temperature RECTISOL ® is also favourable for cryogenic downstream processes, like liquid nitrogen wash, cryogenic recovery of carbon monoxide and oxogas.

Rectisol netl.doe.gov

Rectisol®, independently developed by Linde and Lurgi, is a physical acid gas removal process using an organic solvent (typically methanol) at subzero temperatures, and characteristic of physical acid gas removal (AGR) processes, it can purify synthesis gas down to 0.1 ppm total sulfur, including hydrogen sulfide (H2S) and carbonyl sulfide (COS), and carbon dioxide (CO2) in the ppm range.

Rectisol Wikipedia

Jan 24, 2007 Rectisol is the trade name for an acid gas removal process that uses methanol as a solvent to separate acid gases such as hydrogen sulfide and carbon dioxide from valuable feed gas streams. By doing so, the feed gas is made more suitable for combustion and/or further processing. Rectisol is used most often to treat synthesis gas (primarily hydrogen and carbon monoxide)

Rectisol an overview ScienceDirect Topics

Rectisol ® is a quite flexible process which can be tailored to clean the raw syngas in order to meet the requirements of various type of downstream processes. Depending on the syngas route envisaged, and on the end-use of the side-product streams, namely CO 2 and H2S concentrated flows, the process layout and the operating conditions may differ significantly (Weiss, 1988).

Jun 02, 2006 The Rectisol is a Lurgi AG licensed acid gas removal system. A general rule of thumb is that a Rectisol AGR is going to be about 4x to 5x the cost of a Amine equivalent system.
