The American Gas Association represents local energy companies that deliver natural gas throughout the United States.
A gas manufactured from carbonaceous material whose characteristics are substantially interchangeable with natural gas. The resultant gas is composed primarily of methane. At this writing, SNG feedstocks are the llight hydrocarbons, propane, butane, and the naphthas. Development is underway of processes for production from heavier feedstocks, coal, peat, and solid wastes. See SYNTHETIC NATURAL GAS.
Industry:Energy
Air containing all the water vapor it can hold at its temperature and pressure.
Industry:Energy
A gas obtained by destructive distillation of coal, or by the thermal decomposition of oil, or by the reaction of steam passing through a bed of heated coal or coke, or catalyst beds. Examples are coal gases, coke oven gases, producer gas, blast furnace gas, blue (water) gas, and carbureted water gas. Btu content varies widely.
Industry:Energy
A pressure less than atmospheric pressure, measured either from the base of zero pressure or from the base of atmospheric pressure.
Industry:Energy
The average specified diameter of a pipe divided by the minimum specified wall thickness. NOTE: Each pipe can have two dimension ratios depending on whether the outside or inside diameter is used. In practice, the outside diameter is used if the standard requirement and manufacturing control are based on this diameter. The inside diameter is used when this measure is the controlling one.
Industry:Energy
Natural gas which has been liquefied by reducing its temperature to minus 260 degrees Fahrenheit at atmospheric pressure. It remains a liquid at -116 degrees Fahrenheit and 673 psig. In volume, it occupies 1/600 of that of the vapor at standard conditions.
Industry:Energy
The pressure difference between two points in a system. For example, the difference in pressure between the upstream and downstream taps of an orifice plate, used to measure volume passing through the orifice.
