In January 2014, Roman Abramovich through his Millhouse LLC, which is a Moscow-based asset management company, signed an agreement at the John Houghtaling II house in New Orleans and made a $50 million investment in the American Ethane Company but backed out in late 2015 after the Russian intervention in Ukraine and the Russian annexation of Crimea because of sanctions against Russia.

A gas regulator attached to a nitrogen cylinder. 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.
Will be right back... Thank you for your patience. Our engineers are working quickly to resolve the issue.
The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
The standard Gibbs free energy of formation (G f °) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 °C).
A high purity form can be produced in a small scale by reacting chlorine together with barium carbide. [ 5 ] : 101 In September 1997, it was reported as no longer being produced in the United States for commercial distribution, but was produced as a by-product of industrial chlorination process.
