Chemical industry industrial gas supply and service

Create a positive response

Not only chemicals, but also chemical reactions, that is, combining substances that exist independently, causing them to react and produce new substances. This is how Praxair works with chemical companies. We don't just sell you gas, we work with you to develop new ways to improve processes, achieve environmental goals and reduce production costs. Praxair has the expertise and experience to develop, implement and operate efficient and reliable gas supply systems. In addition, Praxair industrial gases, services and applications will help you advance your chemical production.

Chemical industry industrial gas

Carbon DioxideCarbon Dioxide rollover carbon dioxide

As a raw material, carbon dioxide can be used in the production of organic and inorganic chemicals and can replace harmful solvents in chemical synthesis and separation processes.

Carbon Monoxide Carbon monoxide

Carbon monoxide is the basic constituent element of various major industrial chemicals such as methanol, acetic acid, isocyanates, oxo alcohols and other important chemicals.

HeliumHelium rollover Helium

Helium can remain gaseous even under extremely low temperature conditions. It is used to detect leaks in chemical processes and to cool analytical devices.

HydrogenHydrogen rollover hydrogen

In the chemical industry, hydrogen is mainly used for the production of ammonia and methanol, but it is also very important for the production of other major products, such as aniline, cycloethane, and various non-edible oils, plastics, and insulation materials.

NitrogenNitrogen rollover Nitrogen

Nitrogen is used as a pressurized gas to push liquids through pipes and also to protect oxygen-sensitive materials from air interference.

OxygenOxygen rollover oxygen

Important chemicals such as ethylene oxide and titanium dioxide require the highest purity oxygen. In addition, oxygen can be used to increase the productivity of the oxidation process.

Industrial applications and solutions for the chemical manufacturing industry

Helicopter endothermic oxygen atmosphere

Praxair's helicopter-type endothermic oxygen atmosphere process is a low-cost solution that can be increased as needed. By directly injecting oxygen into the reactor, the yield can be increased by 20%.

Oxygen-enriched combustion

By introducing a small amount of oxygen to the combustion process, the competing needs between productivity and environmental goals can be balanced. As a cost-effective industrial application, Praxair oxyfuel combustion is the best alternative to eliminate bottlenecks and incremental projects.

Reactor cooling

If you need low temperature conditions or rapid cooling, Praxair direct contact, indirect contact, and injection cooling systems are key to increasing productivity.

Nitrogen stripping and recovery

Praxair nitrogen purge systems and applications can purify process fluids. We can also tailor your solution to your purity requirements.

Inerting

Praxair's laminar flow inertization (LBI) technology uses a layer of gaseous nitrogen during the thermoforming process to help you produce molded products and plastic films, which improves surface quality and reduces chipping.

Treatment and recovery of volatile organic compounds

Removes and recovers volatile organic compounds (VOC) from the gas process. Compressing volatile organic compounds will help you recover valuable compounds and meet strict environmental regulations.

Chemical industry industrial services

Praxair not only supplies industrial gases, gas supply systems and applications for the chemical industry, but also works with you to optimize the entire manufacturing process. From consulting to implementation and practical use, Praxair provides you with a complete set of industrial services to assist in monitoring and managing gas supply to improve product quality.
