MATHESON delivers gas, gas handling, application and engineering expertise, as well as the ability to build and maintain onsite plants and subsystems.
Gases and Applications
Chemical Production
Oxygen is a required feedstock in many chemical manufacturing processes, including ethane cracking, ethylene oxide, titanium dioxide, propylene oxide, MEG, vinyl chloride monomer, vinyl acetate monomer. Many of these compounds are the backbone of the petrochemicals industry, so a safe, economical and reliable supply of oxygen is a necessity. Oxygen can also be used in oxidation and liquefaction processes, to produce syngas and for air enrichment.
Hydrogen, carbon monoxide and syngas can also be important in the petrochemical industry. The advent of low cost NG in the US has forged an upturn in the chemical industry, requiring hydrogen, carbon monoxide and syngas from NG. MATHESON can design, build, own and operate facilities to provide a safe and reliable supply of these products to meet process needs of any size.
Hydrogenation, ammonia, methanol, FT, MTR, oxo-alcohols and acetate acid are just a few of the chemical production processes that can benefit from an economical supply of H2, CO or syngas.
Advanced Sulfur Removal Technology
The Nanochem® DDS Series of Deep De-Sulfurization purifiers is a lineup of high performance purifiers specifically targeting sulfur removal to ppm, sub ppm, and even sub-0.1 ppm levels. Nanochem DDS can be used with gas and liquid streams such as: natural gas, liquid hydrocarbons (natural gas liquids, iC4 / iC5 feedstock), fuels (diesel, jet fuel, logistic fuel, bioethanol), LPG, olefins, refinery off-gases. Nanochem DDS sorbents offer high capacity, are regenerable, and can be used for removal of difficult sulfur-containing species such as COS, thiophenes and disulfides.

Sulfur Recovery and Acid Gas Plants
The use of oxygen in a sulfur recovery unit (SRU) can increase plant capacity and help with contaminants and low hydrogen sulfide streams. Oxygen can also be used to boost temperature. Oxygen use can be intermittent or continuous. Hydrogen can also be added to the tail gas treating unit (TGTU) of a sulfur plant when the streams to be treated are leaner (i.e., less H2S).
Pressure and Leak Testing, Purging and Blanketing, Emissions Control, Instrumentation and Safety
An inert gas such as nitrogen finds a multitude of applications in a chemical facility. Nitrogen can be used to pressurize new, repaired, or modified tanks, pipelines or vessels to check process integrity and leak tightness. Plant tanks and storage vessels can be purged and blanketed with nitrogen to displace air and flammable vapors for both safety and quality purposes. Nitrogen can be used to maintain an inert atmosphere to prevent product degradation by contaminants, moisture, or oxygen. Nitrogen helps extend the life and reliability of instrumentation and products. MATHESON supplies nitrogen in a variety of purities and delivery formats.
