The American Gas Association represents local energy companies that deliver natural gas throughout the United States.
A gas resulting from the thermal decomposition of petroleum oils, composed mainly of volatile hydrocarbons and hydrogen. The true heating value of oil gas may vary between 800 and 1600 Btu per cubic foot depending on operating conditions and feedstock properties.
Industry:Energy
Normal course of drilling fluid circulation is downward inside the drill pipe and upward in the well bore space surrounding the drill pipe. On special problems, this normal circulation is sometimes reversed and the fluid returns to the surface through the drill pipe after being pumped down in the annular space.
Industry:Energy
The pressure of natural gas as it is found in the underground formations from which it is produced.
Industry:Energy
To reduce by any process the quantity of water vapor contained in a solid or gas.
Industry:Energy
A gas which forms about 21%, by volume, of the atmosphere. It is chemically very active and is necessary for combustion. The combination of oxygen with other substances generally produces heat.
Industry:Energy
A prime mover in which gas, under pressure or formed by combustion, is directed against a series of turbine blades; the energy in the expanding gas is converted into mechanical energy supplying power at the shaft.
Industry:Energy
A gas which is a product of combustion resulting when carbon unites with sufficient oxygen to produce complete combustion; a component of many natural gases.
Industry:Energy
A gas, the molecule of which is composed of three carbon and eight hydrogen atoms. Propane is present in most natural gas and is the first product refined from crude petroleum. It has many industrial uses and may be used for heating and lighting. Contains approximately 2,500 Btu per cubic foot.
Industry:Energy
The change in length per unit length or the change in volume per unit volume, per degree change in temperature.
