Hydrogen for Hydrotreating & Hydrogeneration
The advent of low-cost natural gas in the US has spurred growth in the chemical industry, increasing demand for hydrogen, carbon monoxide, and syngas derived from natural gas. Economical production of high purity hydrogen, carbon monoxide, and syngas is critical to petroleum refining and chemical industry processes, including chemical synthesis, hydrotreating, hydrocracking, and hydrogenation, ammonia, and methanol production, and other chemicals production processes.
Nippon Sanso Matheson can design, build, own, and operate facilities to provide a safe and reliable supply of these gases.
Applications:
- Removal of sulfur and impurities from feedstocks
- Saturation of hydrocarbons in specialty chemical production
- Production of ammonia, methanol, and other intermediates
Why Nippon Sanso Matheson:
- Advanced on-site generation and pipeline supply solutions for uninterrupted hydrogen availability
- Deep process optimization expertise to improve yield and reduce hydrogen consumption
- Engineering teams that support system design, safety integration, and performance monitoring

Nitrogen for Inerting, Blanketing, Purging and Offloading Tankers

Nitrogen is widely used to create safe, oxygen-free environments and prevent unwanted reactions.
Applications:
- Tank blanketing to prevent oxidation and contamination
- Purging pipelines and vessels during startups and shutdowns
- Explosion prevention in flammable environments
- Pipelines pressure testing
Why Nippon Sanso Matheson:
- Proven inerting system design tailored to plant-specific hazards
- Flexible supply options including bulk, microbulk, and on-site generation
- Trained personnel to help implement best practices for safety compliance and efficiency
Oxygen for Oxidation & Process Intensification
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. Oxygen enhances combustion and oxidation reactions, increasing throughput and efficiency.
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).
Applications:
- Oxidation reactions in chemical synthesis
- Wastewater treatment and biological oxidation
- Combustion enhancement in furnaces and reactors
- Sulfur Recovery and Acid Gas Plants

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.
Carbon Dioxide for pH Control & Chemical Processing
CO₂ plays a vital role in controlling pH and enabling specific chemical reactions.
Applications:
- Neutralization in wastewater treatment
- Carbonation and chemical synthesis
- Temperature control via dry ice and cooling applications
