The American Gas Association represents local energy companies that deliver natural gas throughout the United States.
A person or persons assigned the task of monitoring and controlling daily gas system operations and ensuring safety of a pipeline or distribution system.
Industry:Energy
A valve in which a pierced sphere rotates within the valve body to control the flow of fluids. The sphere may be trunnion mounted or free.
Industry:Energy
Compounds of carbon, sulfur, and hydrogen that are found in gas, such as thiophene.
Industry:Energy
Maintenance of pressure, in all or part of a system, at a predetermined level or within a selected range.
Industry:Energy
The act of threading the drilling line through the sheaves of the travelling block and the crown block. One end of the line is secured to the hoisting drum and the other anchored to the derrick substructure.
Industry:Energy
The minimum pressure required to liquefy a gas at its critical temperature.
Industry:Energy
The use of tracer elements to measure the air infiltration rates within residential and commercial buildings. A number of tracers and capillary absorption tubes are placed within the facility. Natural air infiltration forces the migration of tracers to the capillary absorption tubes. After a set time period, the capillary absorption tubes are analysed using a gas chromatograph. The level of tracer found within the capillary absorption tube is indicative of the building's air infiltration rate.
Industry:Energy
A device for controlling the gas supply to the main burner without manual attention.
Industry:Energy
A method of developing zoned rates. This method involves first segregating costs by zone as if each zone were a separate entity, then developing the unit costs of gas flowing through each zone. The customers in downstream zones pay the costs associated with their gas flowing through the upstream zones.
Industry:Energy
A system using the momentum of a jet of high pressure air (in excess of 5 psig) to entrain gas or air and gas to produce a combustible mixture.
