Natural gas from different gas fields varies in ethane content from less than 1% to more than 6% by volume. Prior to the 1960s, ethane and larger molecules were typically not separated from the methane component of natural gas, but simply burnt along with the methane as a fuel.
For gases, departure from 3 R per mole of atoms is generally due to two factors: (1) failure of the higher quantum-energy-spaced vibration modes in gas molecules to be excited at room temperature, and (2) loss of potential energy degree of freedom for small gas molecules, simply because most of their atoms are not bonded maximally in space to ...
That should eventually send prices soaring to $15,000 per ton, he predicted. Coppers prices are already at record highs, with benchmark prices in London at about $10,000 per ton, more than ...
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.
Over the past decade, the emergence of shale fracking has unlocked a natural gas bonanza in the United States. Production has exploded, and prices have fallen so low that natural gas fuel ...
In 2018, American Ethane began constructing the largest United States export terminal for ethane on the Gulf Coast. [5] [7] [9] The Energy & Minerals Group (EMG), established in Houston by John T. Raymond in 2006, [13] [14] is co-developing the 10 million ton per year ethane port. [9] Construction is to be completed by 2020. [7]
Chlorine was priced at $330 per dry short ton, up $130 on 2008's price of $200. [120] The gas's price steadily increased throughout 2007 and early 2008 as demand for P.V.C. and some metals like copper, Neodymium and Tantalum rose due to the increased growth of the BRIC countries demand for electrical goods.
