Applications and Associated Gases

Hydrocracking, Hydrotreating and Hydrogenation Hydrogen is a key component in a refinery. Hydrogen is required to remove sulfur and contaminants from gasoline and diesel as well as to convert components of crude oil into useful products. Refinery profitability is often directly correlated with the quantity and quality of hydrogen available.

Refineries often produce their own hydrogen, but frequently may not produce the needed volume and purity. Onsite hydrogen plants and pipeline hydrogen can supplement the hydrogen produced by the refinery. MATHESON’s refinery and hydrogen plant experts will work with you toward the ideal solution by assessing your current hydrogen system, examining your needs, and evaluating your options.

Plant Expansion and Gas Clean-up MATHESON has the expertise to help meet your expansion and gas clean-up needs. We can provide technology solutions to increase the capacity of your existing hydrogen plants without additional greenhouse gas emissions. We can also provide equipment to help increase the hydrogen content and remove contaminants from refinery and chemical plant gas streams.

FCC Enrichment and NOx Reduction Oxygen can be added to the regenerator of a fluid catalytic cracker (FCC) to improve yields, assist with coke burning and heat balance, and to reduce cyclone velocities. This can also reduce NOx and CO emissions. Additionally, oxygen is used to produce ozone, which is required in the LoTOx NOx removal equipment incorporated into many FCC units.

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).

Chemicals Production Oxygen is a feedstock in the production of many chemicals, including ethylene oxide, propylene oxide, titanium dioxide, vinyl chloride monomer and vinyl acetate monomer. It can also be used for air enrichment to increase the rate of chemical and combustion reactions.

Hydrogen is used in the production of ammonia, methanol and a number of hydrogenation reactions.

Carbon Monoxide is used in the production of acetic acid, methanol, and polycarbonates.

Syngas (H2/CO blends) is used in oxo-alcohols, methanol, and other chemicals production.

Nitrogen is used primarily for its inert properties (typically to maintain a non-reactive atmospheric blanket), and it is used in the manufacture of ammonia.

Turnaround Services MATHESON has agreements to provide Nitrogen and turnaround services to help your refinery or chemical plant get back up and running as quickly as possible. Using state-of-the-art equipment and MATHESON gases, we can provide cooling, heating and purging services on a short-term or intermittent basis.

Pressure and Leak Testing An inert gas such as Nitrogen can be used to pressurize new, repaired, or modified tanks, pipelines, vessels, and process equipment in order to check their integrity and leak tightness. Dry, high purity nitrogen will not contaminate the system with moisture, lubricants or oxygen (whereas pressure testing with compressed air or water can easily lead to system contamination), although in some cases, Helium or Carbon Dioxide may also be used.

Cryogenic Condensation for VOC Recovery Liquid Nitrogen can be used along with cryogenic recovery equipment to remove and recover volatile organic contaminants from process streams.

Wastewater Treatment The treatment of municipal and industrial wastewater can be made more efficient with the addition of Oxygen. Carbon Dioxide can also be used for pH control.

Purging and Blanketing Inert gas, typically Nitrogen, can be used to displace air, flammable vapors, and contaminants from storage tanks, pipelines, process equipment, railcars, ocean-bound containers, or other vessels. Gas can be used to maintain an inert atmosphere above a liquid or powdered product inside a storage tank, silo, reactor, process equipment, or other container. The gas will help prevent product degradation from moisture and oxygen, control volatile emissions, and safeguard against fires and explosions.

Pipe Freezing Liquid Carbon Dioxide or Nitrogen can be used to freeze a section of a pipeline's contents. The frozen section, or plug, permits work such as valve repairs, the addition of tees or tap offs, or the extension of existing pipelines without draining of the entire system. Only liquids which freeze at the liquid gas temperature, such as water, glycol, and some oils can be handled by the process.

Pressure Transfer The use of Nitrogen to transfer liquid or powder products to and from railcars, tanker trucks, or storage vessels without requiring pumps, mechanical compressors or external power sources. Dry, inert nitrogen is ideal for transferring toxic fluids, highly viscous fluids, ethical pharmaceuticals, flammable products, and materials which become corrosive when contacted with moisture.

Process Chilling and Process Equipment Cooling The use of liquid Nitrogen or Carbon Dioxide as a refrigerant for temperature control in a variety of processes, including solvent recovery, food processing, flour chilling and chemical processes. Liquid gases can achieve a lower temperature and provide a faster cooldown rate than mechanical refrigeration systems. This application may be especially attractive at locations where the generated gases can be used for an additional application, such as blanketing.

Streamlining The use of Oxygen to enrich the air in oxidation processes to increase throughput and improve productivity.

Process Control, Laboratory Analysis and Emissions Monitoring Specialty Gas Mixtures and Calibration Gases are used in laboratories and for process and emissions control. MATHESON has the capabilities to produce the specific gas mixture that is required, including complex mixtures and trace component mixtures.
