With Merichem Technologies exclusive sulfur recovery technology, this patented liquid redox system uses a chelated iron solution to convert H2S into innocuous, elemental sulfur.
Our unique H2S scavengers, adsorbents, and catalyst technologies deliver cost-effective hydrogen sulfide, mercaptan, and oxygen removal across upstream, midstream, and downstream business assets as well as biogas and advanced biotech applications.
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.
Our Skid-Mounted Lead-Lag Vessel Systems using SULFURTRAP® adsorbents provide reliable H2S and light mercaptan removal for oil and gas, biogas, landfill gas and other industrial streams.
Delivering Proven Solutions Worldwide
H2S Treatment Solutions
Liquid redox to remove H2S
LO-CAT
H2S treatment for almost any gas stream including acid gas, natural gas, landfill gas, biogas, CO2 and more; 1 TPD up to 20 TPD.
- Aqueous-based ambient temperature process featuring a chelated-iron catalyst
- Removal efficiencies of over 99.9%, process guarantees less than 1 ppm H2S
- Up to 100% turndown
- Continuously regenerated catalyst for low operating costs
- No liquid waste streams
- No hazardous waste products produced
Adsorbents to treat H2S
SULFURTRAP
H2S treatment using SULFURTRAP for almost any gas stream including acid gas, natural gas, landfill gas, biogas, CO2 and more; 0 TPD up to 1.5 TPD.
Our products are proven around the world to increase process efficiency, minimize downtime, and reduce operating costs.
UHC
Ideal for removing H2S in demanding environments. Specially formulated to minimize changeouts, this advanced high-sulfur tonnage adsorbent offers the lowest cost per pound of sulfur removed on the market.
EX
Extended life, low pressure drop, easy changeout iron-based pellets for gas phase applications. Lasts 2-3 times longer than the leading hydrogen sulfide adsorbent.
HTD
Safe and reliable adsorbent effectively eliminating H2S from gas streams in batch processing. Exceptional performance at mid to high temperatures.
ST1
Low-cost solution for effective H2S removal from gas streams, specifically designed for processes where a modest cost for media is necessary, or for applications with low to medium sulfur removal requirements.
Caustic treatment of H2S
THIOLEX
Mass transfer technology using a patented FIBER FILM® Contactor, eliminating carryover and allowing a smaller footprint for treatment.
Caustic or amine treatment of H2S, mercaptans and/or COS.
- Dramatically reduces capital expenditures and space requirements compared to other extraction and treating alternatives
- No prewash required (unless caustic make-up is prohibitive)
- Low caustic make-up when combined with REGEN® system
- Total sulfur reduction and achieves low total sulfur specification
- More design and operational flexibility to remove H2S and RSH in NGL C3+ streams, increasing sales and profitability
- Additional separation vessels not required

We’re Here to Remove H2S.
Selecting the right H₂S removal solution for your operations
Merichem Technologies has a solution for the H2S present in your streams. The chart offers suggested ranges for our SULFURTRAP® media and LO-CAT® liquid redox technology.
If your flow or H2S concentration is between the two areas, we are happy to help you confirm which system could be most appropriate based on the needs of your operations.
