Innovative Process Solutions Powered by Expert Service
Remove RSH, H2S, CO2 and COS with THIOLEX™
Featuring our proprietary FIBER FILM® Contactor, Merichem’s THIOLEX™ technology uses a caustic solution to remove mercaptan compounds and other impurities. It allows for total sulfur reduction in hydrocarbon streams to meet client specifications while delivering greater design and operational flexibility, improving sales and profits.
H2S Removal with LO-CAT®
Merichem’s patented liquid redox system uses a chelated iron solution to convert dangerous H2S into innocuous, elemental sulfur. Chemical-based, it offers greater reliability and flexibility than biological treatment—with no liquid waste streams or waste products.
Regenerate Spent Caustic Product with REGEN®
Merichem’s REGEN® technology reduces caustic consumption through the regeneration of the caustic solution. With applications in all caustic streams used in mercaptan treating processes, it allows mercaptides to be oxidized into disulfide oil (DSO), recovering sodium hydroxide and minimizing virgin caustic consumption.
Treat Your Spent Caustic On‑Site with MERICON™
MERICON™ I, II, and III treatment technologies are used in the processing of spent caustic products for BOD / COD reduction, odor control, and pH adjustment to allow the final stream to meet specifications for wastewater treating facilities.
Spent Caustic Handling for Beneficial Reuse
Merichem® is a leader in the beneficial reuse of spent caustic products, reducing waste reporting at the source and offering eco-friendly options by reusing spent caustics as-is as a substitute for commercial products. Merichem’s reuse of spent caustics dramatically reduces your costs and environmental footprint with a strong service commitment towards safe and responsible stewardship.

Industries We Serve
For a wide range of applications worldwide, Merichem® offers proven solutions for treating sulfur and other impurities. We can also support clients in the management of spent caustic products for beneficial reuse, promoting sustainability or technology solutions to allow caustics to be sent to waste-water treatment systems.
Merichem® provides solutions for oil and gas applications, chemical and petrochemical plants, including complete treatment units engineered and fabricated to client specifications. Alternatively, Merichem® can fast-track a project using Merichem’s specifications when this better fits a client’s needs.
Merichem® offers direct treatment solutions to remove H2S from most types of gas streams, including natural gas, air, CO2, acid gas, biogas, landfill gas, refinery gas, and more. Merichem® also offers liquid treating solutions to remove or sweeten sulfur compounds to meet pipeline and fractionator specifications for our midstream clients. Our ability to fast-track our projects using Merichem’s standards also fits in the needs of our midstream clients’ schedule requirements and ensures our clients can be up and running quickly.
Merichem® has cost-effective solutions for the treatment of whole crude, crude sweetening, and sulfur extraction without the decomposition of DSO back to RSH.
With our patented LO-CAT® technology, Merichem® accommodates specialty applications for H2S removal from any acid gas stream.
Pulp & Paper
Merichem® serves the pulp and paper industry with cost effective spent caustic and sodium hydrosulfide products for white liquor make-up. Beneficial reuse of spent caustic products in the pulping process promotes recycling and helps companies meet sustainability goals and lower costs.
Biofuels & Renewables
Merichem® provides solutions that desulfurize biofuels and renewables. Designed to significantly reduce CAPEX and OPEX, our proven technologies remove sulfur and other acidic impurities from process streams, ensuring product streams meet specifications.
