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.
Efficient, easy to operate sulfur treating for varying feeds and conditions with minimal aqueous carryover.
We’ve treated Mercaptans, H2S and COS all over the world.
For over 50 years we’ve helped clients like you, reliably and economically treat Mercaptans, H2S, COS and other sulfur contaminants.
With a worldwide presence, our experience includes a wide variety of industry sectors, feedstocks, treating requirements, and regulations.
With FIBER FILM® Contactor technologies, you benefit from:
- High turndown to 15% for light hydrocarbon streams
- Smaller vessels for compact footprint; easy to retrofit existing vessels
- Easy operation and low maintenance requirements, minimizing manpower
- Minimum consumption of treatment chemicals and utilities for lower OPEX
- Expert technical support from over 50 years of delivering reliable sulfur treatment solutions
Liquid Treating Solutions for Mercaptans, H2S, COS and Other Acids
Engineered for reliable, low maintenance H2S removal, even under variable conditions
Caustic Treating
THIOLEX™
THIOLEX™ is a proven technology effectively removing mercaptan compounds (RSH), hydrogen sulfide (H2S), carbon dioxide (CO2), carbonyl sulfide (COS), and elemental sulfur.
- No prewash step is required (unless caustic make-up is prohibitive)
- Low caustic make-up when combined with our REGEN® spent caustic regeneration system
- Total sulfur reduction; Achieves low total sulfur specification
- Extraction efficiency is best between 60°F to 115° F
- Gives more design and operational flexibility to remove H2S and RSH in NGL C3+ streams, increasing sales and profitability
- High-efficiency mass transfer with minimal aqueous carryover
- Additional separation vessels not required
Amine Treating
AMINEX™
AMINEX™ is a proven technology for the removal of acid gas (H2S + CO2) and carbonyl sulfide (COS) from LPG-type liquid and gas streams.
- Mitigates corrosion and plugging with no tray or packing internals
- Eliminates amine carryover
- Operates efficiently over wide range of throughputs and operating conditions
- Easily retrofit existing vessels
- No foaming
Water Wash
AQUAFINING™
AQUAFINING™ is a proven technology in the removal of dissolved and free-phase carryover of caustics, amines, surfactants and oxygenates
- Water-makeup is reduced to a minimum consumption, while reducing CAPEX and space requirements
- Process produces spent alkaline water that can be easily handled in wastewater treatment plants
Naphthenic Acid Extraction
NAPFINING™
NAPFINING™ is a proven solution for removing naphthenic acid compounds from jet fuel, kerosene, diesel, condensate and crude oil streams—without causing debilitating emulsions.
- Reduce space cost requirements for operators
- Minimal emulsion formation
- Better performance than electrostatic precipitation for emulsion prevention
- Ideal solution for removal of TAN from hydrocarbons in the range of 0.1 to 1 mg KOH/g or above; has commercially treated up to 0.5 TAN in the feed
