LINDE Rectisol Process - The most economic and experienced wash process for removal of sulfur compounds and CO2 from Gasification gases
The Rectisol wash process is a well-proven process for the removal of H2S/COS and CO2 from coal, asphalt, pitch or oil derived synthesis gas. It is a physical gas wash system using methanol as solvent at operating temperatures below water freezing point, to produce a synthesis gas with less than 0.1 vppm of total sulfur. The CO2 content can be adjusted in a range from several mol-percent down to a few ppm, as is required by the specified application. Its main advantages are the use of cheap and readily available methanol as solvent, the very flexible process configuration, and rather low utility consumption figures compared with other wash processes, like PEGE based process or chemical washes. A modern concept of a Rectisol unit is described, to treat shifted and un-shifted gases in just one plant: 1. Shifted gas was used for hydrotreating in a refinery. 2. Unshifted gas was used as fuelgas for power generation in an IGCC. 3. CO2 of the unshifted feed gas was removed only partly, because the remaining CO2 was fed as inertgas together with the fuelgas to an IGCC (Integrated Gasification Combined Cycle). 4. All sulfur compounds of both feed gases were concentrated in one single stream with a high H2S concentration. 5. Disturbing impurities like NH3, HCN or metal carbonyls were eliminated nearly quantitatively.
