H2S Removal with LO-CAT® Liquid Redox for Gas Streams

The LO-CAT process, available exclusively from Merichem Technologies, is a liquid redox system that uses a proprietary chelated iron solution to convert H2S to elemental sulphur in the form of an environmentally friendly sulfur cake. It does not use any toxic chemicals and does not produce any hazardous waste byproducts. The environmentally safe catalyst is continuously regenerated in the process.

Advantages

• Available process guarantees <1 ppm H2S
• Low operating cost; Lower OPEX vs. scavengers; lower CAPEX vs. Claus plants
• More reliable & flexible than biological treatment
• No liquid waste streams
• No hazardous waste products produced
• High turndown (up to 100%)
• Highly customizable to specific treatment needs
• Aqueous-based process at low temperatures
• 99.9% or more reduction of H2S
• Continuously regenerated catalyst
• Reliable & cost -efficient removal of H2S; easily accommodates sulfur loads up to 20 tons/day
• Directly treat gas streams or serve as the sulphur recovery unit (SRU) downstream of acid-gas removal (amine) unit
