Cost effectively treat refinery gas streams

American Oil & Gas’s gas treating, extraction Merox process utilizes a high efficiency gas-liquid contacting design to extract low molecular weight mercaptans from a refinery gas stream using a strong aqueous caustic solution.

The mercaptide-rich solvent, which contains the Merox catalyst, is sent to the regeneration section where air is injected and the mercaptides present are oxidized to disulfides.

The disulfides are subsequently separated from the solvent and; the regenerated lean caustic solvent is recycled back to the Merox Extractor. Typical product mercaptan levels can be controlled to less than 10 wppm.
