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 traveling 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 analyzed 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 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
All sediments of rock that cover or overlie the reservoir rock.
