Airgas, an Air Liquide company, is an American supplier of industrial, medical and specialty gases (delivered in packaged or cylinder form), as well as hardgoods and related products; one of the largest U.S. suppliers of safety products; and a leading U.S. supplier of ammonia products and process chemicals.
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 Products and Chemicals, Inc. is an American international corporation whose principal business is selling gases and chemicals for industrial use. Air Products is headquartered in Trexlertown, Pennsylvania, in the Lehigh Valley region of eastern Pennsylvania. As of 2024, Air Products is the fifth-largest employer in the Lehigh Valley. [2]
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 ...
The industry producing these gases is also known as industrial gas, which is seen as also encompassing the supply of equipment and technology to produce and use the gases. [1] Their production is a part of the wider chemical Industry (where industrial gases are often seen as " specialty chemicals ").
WASHINGTON (Reuters) -U.S. manufacturing contracted at a moderate pace in November, with orders growing for the first time in eight months and factories facing significantly lower prices for inputs.
The sulfur is present in the form of hydrogen sulfide, a toxic gas that must be removed for safety reasons. Most natural gas has less than 1 percent hydrogen sulfide, but deposits have been discovered with more than 80 percent hydrogen sulfide. [2] Sour gas is most often associated with carbonate rocks, and especially with anhydrite. [3]
Modern methods to detect asphyxiant gases in mines led to the Federal Mine Safety and Health Act of 1977 in the United States which established ventilation standards in which mines should be "ventilated by a current of air containing not less than 19.5 volume per centum of oxygen, not more than 0.5 volume per centum of carbon dioxide".
