Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". [12][13] It was an accidental discovery while attempting to isolate potassium metal. By heating potassium carbonate with carbon at very high temperatures, he produced a residue of what is now known as potassium carbide, (K 2 C 2), which reacted ...
A cutting torch being used to cut a steel pipe. Oxy-acetylene Welding (OAW) station. Oxy-fuel welding torch (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline or petrol, diesel, biodiesel, kerosene, etc) and oxygen to ...
MAPP gas was a trademarked name, belonging to The Linde Group, a division of the former global chemical giant Union Carbide, for a fuel gas based on a stabilized mixture of methylacetylene (propyne), propadiene and propane. The name comes from the original chemical composition, methylacetylene-propadiene propane.
The gas industry did not cede the gas lighting market to electricity immediately, as the invention of the Welsbach mantle, a refractory mesh bag heated to incandescence by a mostly non-luminous flame within, dramatically increased the efficiency of gas lighting. Acetylene was also used from about 1898 for gas cooking and gas lighting (see ...
Gas cylinder. Industrial compressed gas cylinders used for oxy-fuel welding and cutting of steel. A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure. Gas storage cylinders may also be called bottles. Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid ...
Industrial gas. Industrial gases are the gaseous materials that are manufactured for use in industry. The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders. The industry producing these gases is also known as industrial ...
