The American Gas Association represents local energy companies that deliver natural gas throughout the United States.
A solid ice-like material resulting from the combination of a gas with water under pressure. Of natural gas constituents -- methane, ethane, propane, isobutane, normal butane, and also hydrogen sulfide and carbon dioxide will form hydrates. The greater the pressure in the equipment, the higher the temperature at which the hydrate will form, usually well above freezing. Hydrates can cause restriction or stoppage of flow, and can be controlled by alcohol injection or by dehydration of the gas. Methane hydrates are found in some permafrost regions and beneath portions of the ocean floor and may eventually be a source of methane gas.

Once the preliminary determination is issued, sponsors can line up financing and begin right-of-way acquisition and be ready to go when the lengthy environmental process is completed and they receive unconditional certificate authorization.
Industry:Energy
A solid, semisolid, or pseudosolid organic material, often of high molecular weight, which exhibits a tendency to flow when subjected to stress, usually has a softening or melting range, and usually fractures conchoidally.

The first of the paraffin series of hydrocarbons. The chief constituent of natural gas. Pure methane has a heating value of 1012 Btu per cubic foot.
Industry:Energy
The sale or assignment of a specific right to firm transportation (or storage) on an interstate natural gas pipeline to another entity. In some instances, transportation capacity rights may be rebrokered. The Commission's general policy is to require the initial assignor or broker to remain obligated to the pipeline for scheduling and payment of charges.
Industry:Energy
A means which provides for automatic lighting of gas at the burner when the gas valve controlling flow is turned on and will effect relighting if the flame on the burner has been extinguished by means other than closing the gas burner valve.
