Refining

Industrial gas supply and equipment for the refining industry

Prospects of the refining industry

Praxair has 50 years and more than 1 billion standard cubic feet of daily hydrogen storage capacity. Our extensive product experience and scope will help you to be invincible in today's challenging business environment. Hydrogen is vital to producing cleaner transportation fuels, and we have the capacity to transport your hydrogen safely and efficiently.

Our work team has decades of experience in hydrogen production, recovery systems and pipeline networks worldwide, enabling efficient, reliable design, implementation and implementation. In addition, we have specialized application technologies for the refining industry. These technologies require extremely low levels of oxygen, using oxygen and other industrial gases to increase the capacity of processing equipment, reduce emissions and increase reliability.

Refinery industry gases

HydrogenHydrogen rollover hydrogen

Hydrogen is an indispensable gas in the refining industry today when refining heavy crude oil into refined fuels, helping to meet increasingly stringent technical requirements for transportation fuels.

OxygenOxygen rollover oxygen

Oxygen is widely used in oil refineries to increase the production capacity of fluid catalytic cracking (FCC) equipment and sulfur recovery units (SRU) and improve wastewater treatment.

NitrogenNitrogen rollover Nitrogen

As an industrial gas used to protect storage tanks and purification pipelines, nitrogen can also remove volatile organic compounds (VOC) from chemical process streams and wastewater, reducing volatile organic compound emissions.

Industrial applications in the refining industry

Emission reduction of fluid bed catalytic cracking equipment

Praxair's carbon monoxide and nitrogen oxide application technology can reduce carbon monoxide and nitrogen oxide emissions by up to 60% and improve the operational flexibility of fluid bed catalytic cracking equipment.

Oxygen enrichment in fluid bed catalytic cracking equipment (FCC)

Praxair oxygen enrichment technology can increase the capacity of fluid bed catalytic cracking equipment (FCC) regenerators by up to 35%.

Aerated combustion

The application of Praxair oxyfuel combustion technology to flame heaters will reduce fuel consumption and increase output, ultimately increasing heater efficiency and reducing nitrogen oxide emissions. Oxyfuel combustion has the least capital expenditure and is the best way to eliminate heater bottlenecks.

Aerobic reforming

By injecting oxygen to the combustion side of the reformer, the hydrogen production from a steam methane reformer (SMR) can be increased by 10-15%

Refinery gas processing

Transfer almost all fuel gas streams, including large amounts of olefins and heavy hydrocarbons, to qualified steam methane reformers (SMR) or gas turbines. This technology is the best alternative to standard hydroprocessing, which reduces organic sulfur levels in fuel gases to meet stringent environmental goals. With our refinery gas processing technology, hydrogen and liquefied petroleum gas can be extracted from refinery gas streams.

Sulfur processing equipment

By injecting oxygen, the capacity of the sulfur recovery unit (SRU) is increased.

Treatment and recovery of volatile organic compounds

Using the same liquid nitrogen source used in the refinery for covering and removing, this industrial application can compress the volatile organic compounds in the industrial production stream, restore valuable products and retain nitrogen for covering and removing operations.
