What does Air Liquide do?

Air Liquide S.A. (French pronunciation: ​[ɛʁ likid]; /ˌɛər lɪˈkiːd/; literally “liquid air”), is a French multinational company which supplies industrial gases and services to various industries including medical, chemical and electronic manufacturers.

What is ASU process?

ASU uses multi-column cryogenic distillation process to produce gaseous oxygen and nitrogen (at above atmospheric pressure and near ambient temperature). The gas liquefaction is a process to form liquid from a gas through compression and cooling.

Can you make liquid air?

Air can also be liquefied by Claude’s process, which combines cooling by Joule–Thomson effect, isentropic expansion and regenerative cooling.

Is Air Liquide an EPC?

As an experienced international Engineering, Procurement and Construction (EPC) contractor, we are executing some of the most challenging projects today to meet the needs of our customers and the energy transition.

Who is CEO of Air Liquide?

Benoît Potier (2006–)Air Liquide / CEO

How does Air Liquide produce hydrogen?

Carbon capture Today, the majority of hydrogen is produced from natural gas through the steam methane reforming (SMR) process. Air Liquide has developed an innovative cold capture system (Cryocap™) that captures the CO₂ released during this hydrogen production through a cryogenic process.

What is ASU in oxygen plant?

A cryogenic air separation unit (ASU) is a plant that utilizes the distinct properties between the primary components of air to produce highly purified oxygen, nitrogen, and sometimes other gases, such as argon.

How is liquid oxygen made?

Liquid oxygen is obtained from the oxygen found naturally in air by fractional distillation in a cryogenic air separation plant. Air forces have long recognized the strategic importance of liquid oxygen, both as an oxidizer and as a supply of gaseous oxygen for breathing in hospitals and high-altitude aircraft flights.

How does electrolysis produce hydrogen?

Electrolysis is a promising option for carbon-free hydrogen production from renewable and nuclear resources. Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This reaction takes place in a unit called an electrolyzer.
