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.
