Natural gasis a mixture of hydrocarbons that exists in agaseous stateatstandard temperature and pressure. Methane (CH4) is the main constituent, but the presence of higher molecular-weight alkanes, including ethane, propane, and butane, changes the average stoichiometric composition for natural gas,...
Repower your fleets/trucks to run on Compressed Natural Gas (CNG) with our natural gas conversion program. Convert to natural gas with Repowered NGV.
On the other hand, depending on the type of fuel used we may find solid fuel boilers (firewood, coal or pellets), liquid fuels (gas oil), or gases (butane, propane or natural gas) and, finally, we also have electric boilers. The gas boiler is the most used in the current market, ...
Referring to FIG. 1, the operation of the natural gas detecting apparatus 10 provided by the present invention is based upon the absorption of infrared energy by a gas sample as the gas sample is pumped through a gas sample chamber defined by an optical cell 12. The natural gas detector 10...
Biodegradation also discriminates against 13CC3, leading to isotopically heavy residual propane44. In the Siljan gas, the anomalously heavy δ13CC3 values compared to the δ13CC2 values, the high C2 to C3 ratios that are far from the normal range for thermogenic gases, as well as other ...
Further separation of the gas into NGLs such as propane, butane, ethane, and pentane+ (plant condensate) is done during the processing of the natural gas, usually by centrifuge. Natural gas – Western Canada If we look at the production of natural gas in Western Canada (BC, Alberta and Sa...
1.9.3 Compressed Natural Gas (CNG) Gas can be transported in containers at high pressures, typically 1,800 psig for a rich gas (significant amounts of ethane, propane, etc.) to roughly 3,600 psig for a lean gas (mainly methane). Gas at these pressures is termed compressed natural gas ...
The purification of hydrocarbon gases by any of these processes is an important part ofgas refining, especially regarding the production of LPG. This is a mixture of propane and butane, which is an important domestic fuel, as well as an intermediate material in the manufacture ofpetrochemicals(Sp...
A process and apparatus for the recovery of ethane, ethylene, propane, propylene, and heavier hydrocarbons from a liquefied natural gas (LNG) stream is disclosed. The LNG feed stream is divided into two portions. The first portion is supplied to a fractionation column at an upper mid-column ...
A method for continuous pressure swing adsorption separation of a pressurized feed gas stream, including separating hydrocarbons heavier than methane from the pressurized feed gas s
