Uses and applications of hydrogen and liquid hydrogen in various industries

Aerospace

As a power source, hydrogen can power rockets and life support systems and computers in the space environment. It can also be used for metal sintering and annealing.

Automotive and transportation equipment

When hydrogen is used as a heat treatment furnace gas, it can react with oxygen to produce a shiny surface for steel parts. In addition, the high heat transfer performance of hydrogen makes it an excellent industrial quenching gas. When used as an alternative fuel, hydrogen can also effectively reduce harmful gas emissions.

energy

Praxair's hydrogen can be used to power ultra-high-speed ground vehicles, fuel cell passenger cars, buses and forklifts.

Refining

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

Welding and metal processing

Hydrogen is often mixed with argon for stainless steel welding when performing plasma welding and cutting operations.

Hydrogen (H 2 ) supply methods: storage tanks, cylinders, other containers, pipes and hydrogen plants

Cylinder

Praxair understands the impact of gas supply systems on customers 'products and knows how to optimize operations by improving customers' current methods. We work with customers to perform process analysis and advise on improving the quality and stability of beef and pork products.

pipeline

Praxair provides advanced hydrogen pipeline operation services for large-scale users in multiple key areas of refining and chemical activities. We control and monitor all hydrogen pipelines to ensure that gas purity, flow and pressure meet customer requirements.

On-site production

For customers with a large demand for hydrogen but no Praxair gas supply pipeline nearby, our on-site hydrogen production equipment can completely achieve uninterrupted gas supply according to purity, pressure and flow requirements. Praxair field equipment can supply up to one million standard cubic feet of gas per day, and when liquid hydrogen cannot meet the demand, we can also build small on-site hydrogen production equipment for customers with medium hydrogen demand.
