In addition to water treatment applications, ion exchange resins can be used in many different specialized applications such as pharmaceuticals, fine chemicals, chemical processing, mining, catalysts, sweeteners processing, beverage and dairy processing, nuclear applications, bio-fuels and other demanding processes.
Product and process development and contract manufacturing services to the specialty and fine chemicals industries. Key processes include distillation, reactive distillation, batch and continuous fractionation, advanced separations, batch reactions, continuous reactions and multi-step organic reactions.
Epoxies deliver the high performance required to combat corrosion and withstand higher temperatures and pressure requirements in a wide variety of oil and gas and chemical processing applications.
Removal of acidic components from natural gas and scrub impurities in refinery gas and ammonia production. UCARSOL™ Gas Treating Amines and SELEXOL™ solvents, remove carbon dioxide, hydrogen sulfide and other impurities from natural and refinery gases. The UCARSEP™ Amine Reclamation System removes heat-stable salts on-line. A full range of gas treating services is also provided.
Ethylene glycols (EG) and their derivatives are used in natural gas hydration and treating applications to remove water and impurities.
Ethylene oxide (EO) and its derivates are used to produce materials for natural and refinery gas treating, drying and purification.
Waterflood injection operations for offshore oil production can benefit from low-sulfate water. By selectively removing sulfate from the injected seawater, FILMTEC™ membranes are able to prevent barium sulfate scaling and the associated loss of reservoir flow. These elements offer high rejection of dissolved solids and organics and operate very efficiently at lower pressures. FILMTEC elements also provide excellent structural stability and are more productive than other elements.
Advanced gas treatment products and technology including UCARSOL™ solvents, DOW Specialty Amines, SELEXOL™ and UCARSEP™Amine Reclamation System, UCARKLEAN™ solutions, DOW Gas Treating Chelants and RT-2 Technology.
Industrial Chemicals: blowing agents and additives, catalyst carrier liquids, solvents and extracting agents.
DOWTHERM™ Q Heat Transfer Fluid additive for waste heat recovery in oil applications, solvent regeneration and natural gas purification. Compared to how oils, DOWTHERM Q exhibits better thermal stability, particularly at the upper end of hot oil's use range. and significantly better low-temperature pumpability. SYLTHERM† heat transfer fluid is a highly stable, long-lasting silicone fluid designed for high temperature liquid phase operation.

Used in gas conditioning where greater selectivity than ethanolamines to CO2 and H2S is required. Neutralizes crude oil to reduce corrosion.
Methyl CARBITOL™ Solvent is used as an additive in jet fuels to prevent ice buildup in fuel lines and to inhibit growth of bacteria in fuel tanks of primarily military and private aircraft.
Uses of polyglycols include acid gas treatment, crude oil demulsifiers, drilling fluid additives, fuel additives; metal corrosion inhibitors in oil wells producing brine that contains hydrogen sulfide or carbon dioxide, modifiers for silica-filled petroleum asphalt to improve softening points, temperature susceptibility, and high resistance to flow and as selective solvents for removing halogens from hydrocarbons.
When natural gas is recovered, its water content may need to be lowered to prevent water from condensing in pipelines and freezing, or from forming hydrocarbon hydrates. Hydrates can foul instruments and reduce line capacity.The hygroscopic nature of Propylene Glycol Industrial Grade (PGI) makes it an effective dehydrating fluid for use in the natural gas processing industry.
Propylene Oxide is a versatile chemical intermediate used in a wide range of industrial and commercial products including flame retardants, synthetic lubricants, oil-drilling chemicals and textile surfactants.
SELEXOL™ solvent has been proven effective and economical in a variety of gas treating applications, including:
- Purification of lean natural gas
- Low-energy ammonia/urea production
- Coal gasification
- Heavy oil partial oxidation
- Landfill gas purification
- Light hydrocarbon dew point control
SELEXOL solvent is particularly effective in high-pressure, low-temperature, high-acid gas systems.
Drilling fluids, acidizing and stimulation, drilling cutting and well cleaning, enhanced oil recovery.
The broad product line of UCON™ formulated fluids and lubricants, including compressor lubricants and base stocks products that can outperform petroleum oils.
VERSENE™ Chelating Agents are used in drilling, production, and recovery of oil. They can prevent plugging caused by iron precipitation during stimulation and fracturing. Used for scale removal and prevention on well casings and boilers used for enhanced oil recovery steam flooding. They also remove calcium and other forms of scale without corrosion from boilers, evaporators, heat exchanges and filter cloths. Also used in the surface preparation, cleaning, finishing and plating of metalworking.
Styrene-DVB copolymer beads can be used as 'plastic ball bearings' to lubricate drilling operations.
