Liquid Treating Solutions for Mercaptans, H2S, COS and Other Acids
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
