Extracting RSH, H2S, CO2, and COS from Liquid and Gas Streams
THIOLEX™ | Caustic Extraction of Contaminants
First licensed in 1980, Merichem Technologies THIOLEX™ uses our proprietary FIBER FILM® Contactor as the mass transfer device, with caustic as the treating reagent in liquid and gas hydrocarbon streams.
THIOLEX™ technology effectively removes mercaptan compounds (RSH), hydrogen sulfide (H2S), carbon dioxide (CO2), carbonyl sulfide (COS), and elemental sulfur. THIOLEX™ COS, which uses MEA / caustic, is also extremely effective at hydrolyzing Carbonyl Sulfide (COS) to meet a client’s specifications.
Advantages
Combined with the highly efficient FIBER FILM Contactor, THIOLEX™ technology dramatically reduces capital expenditures and space requirements compared to other extraction and treating alternatives.
- No prewash required (unless caustic make-up is prohibitive)
- Uses caustic solution to remove impurities
- Low caustic make-up when combined with REGEN® system
- Total sulfur reduction
- Achieves low total sulfur specification
- Extraction efficiency best between 60°F to 115° F
- Gives midstream customers more design and operational flexibility to remove H2S and RSH in NGL C3+ streams, increasing sales and profitability
- Excellent and proven technology for removal of sulfur impurities (RSH, H2S, COS); due to high-efficiency mass transfer, additional separation vessels not required
