The American Gas Association represents local energy companies that deliver natural gas throughout the United States.
(1) A technique to reduce corrosion of a metal surface under some conditions by passing sufficient anodic current to it to cause the electrode potential of the surface to enter and remain in the passive region. (2) An appreciable reduction in corrosion by making a metal an anode and maintaining this highly polarised condition with very little current flow.
Industry:Energy
A gasifier in which coke is fed into the top keeping the gasifier essentially full when operating. Ash is removed at the bottom while the coal is consumed as it moves downward through the bed.
Industry:Energy
A process by which the interconnected operators will transfer a quantity greater or less than the confirmed nominations scheduled quantity for various contracts at a point in an attempt to make the total gas received or delivered at the point as close as possible to the scheduled quantity during a specific billing period.

American National Standards Institute X12 Committee - The committee sanctioned by ANSI for developing and maintaining U.S. standards for business-to-business electronic data interchange pertaining to trade transactions, with business-to-business defined broadly to include all organisations but excluding all individual consumers.
Industry:Energy
Energy Efficiency Ratio (EER) - a ratio calculated by dividing the cooling capacity in Btu per hour by the power input in watts at any given set of rating conditions. Heating Seasonal Performance Factor (HSPF) - the total heating output of a heat pump during its normal annual usage period for heating divided by the total electric power input in watt-hours during the same period. Seasonal Energy Efficiency Ratio (SEER) - the total cooling capacity of a central unitary air conditioner or unitary heat pump in Btu's during its normal annual usage period for cooling divided by the total electric energy input in watt-hours during the same period.
Industry:Energy
Oil in a reservoir underlying a gas-cap. In a reservoir on an anticlinal structure with a large gas-cap the centre of the field area may consist only of gas wells with a ring of oil wells surrounding the gas producing area, hence the term oil ring.
Industry:Energy
The combination of mixer head, mixer throat, and mixer tube. Mixer Head. That portion of an injection type burner, usually enlarged, into which primary air flows to mix with the gas stream. Mixer Throat. That portion of the mixer which has the smallest cross sectional area and which lies between the mixer head and the mixer tube. Mixer Tube. That portion of the mixer which lies between the throat and the burner head.
Industry:Energy
The principal vertical pipe which conducts the gas from the metre to the different floors of the building.
Industry:Energy
To tighten the bolts on a hatch cover or manhole plate so that no leakage will occur from or into the vessel when operating.
Industry:Energy
(1) polarisation of anode, that is, the decrease in the initial anode potential resulting from current flow effects at or near the anode surface. The potential becomes more noble (more positive) because of anodic polarization. (2) That portion of the cell polarisation occurring at the anode.
