RECTISOL® is the most well known proprietary Linde scrubbing process and can simultaneously remove all above mentioned sour gas components in one process step. RECTISOL® is selected for many oil and coal gasification projects.

Linde can build other chemical and physical wash processes including various types of amine wash systems, MEA, MDEA, DEA, Benfield, Sulfinol, Polar-1, Caustic, NMP, Alkacid wash and others.

Sulfur recovery

Gas purification by scrubbing results in the enrichment of sour gas components in the regeneration gas of the scrubbing unit. CLINSULF® is a catalytic process of sulfur recovery converting the H2S content of the regeneration gas into elemental sulfur by reaction with oxygen.

The process is based on the Linde Isothermal reactor filled with a suitable catalyst. CLINSULF® DO (direct oxidation) and CLINSULF® Sub Dewpoint are the two configurations of this process that typically are applied to process off-gases from amine wash, partial oxidation plants, Claus off-gas or for the desulfurization of biogas.
