[13] In 2019, Airgas signed a definitive agreement to acquire TA Corporate Holdings, Inc. (“Tech Air”), a large independent distributor of industrial gases and welding supplies serving various geographies in the United States.
The solubility of gas obeys Henry's law, that is, the amount of a dissolved gas in a liquid is proportional to its partial pressure. Therefore, placing a solution under reduced pressure makes the dissolved gas less soluble. Sonication and stirring under reduced pressure can usually enhance the efficiency.
Air Liquide supply them with gas and energy by direct pipeline. Its pipeline network in the largest industrial basins is the longest in the world (more than 9000 km).

Oxygen and Nitrogen are two non-condensable gases that are removed by deaeration. Henry's law describes the relationship of dissolved gases and partial pressures. Thermal deaeration relies on the principle that the solubility of a gas in water decreases as the water temperature increases and approaches its boiling point. In the deaerator, water ...
