A well through which the injection gas or other fluid flows into the underground formation.

Gas entering a processing plant, facility, or individual piece of equipment.

A method for removing hydrogen sulfide (H2S) from natural gas by passing the gas over a bed of wood shavings which have been injected with a form of iron oxide.

A hydrocarbon of the paraffin series with the formula C4H10 having its carbon atoms branched (2-methylpropane).

Water which fills, or is circulated through, a casing which partially or wholly surrounds a vessel or machine element in order to remove, add, or distribute heat and, thereby, to control the temperature within the vessel or element.

Rail tank cars having capacities of 30,000 gallons (114m3) or more.

A vessel used to separate free liquids from flowing streams.

A method for detecting the presence of hydrogen sulfide in a fluid by discoloration of paper which has been moistened with lead acetate solution.

Amine solution that has been stripped of absorbed acid gases giving a solution suitable for recirculation to the contactor.

Gas containing little or no recoverable natural gas liquids.

Oil from which the absorbed constituents have been removed.

Low boiling point components of a hydrocarbon fluid.

Low molecular weight hydrocarbons.

The process whereby a substance in its gaseous or solid state is liquefied.

The components of a hydrocarbon gas which are typically recovered as liquid products.

A liquid used to remove water from other fluids.

A structural and piping installation alongside a railroad track or roadway used for the purpose of filling and/or emptying railcars or trucks.

Adding piping with a connection to an existing line at each end.

(1) In contractual terms, the amount of gas delivery specified for which a buyer has paid for but not taken. (2) In gas processing, the amount of gas required to keep the inlet volume or energy whole at the outlet. This is typically defined by contract or regulation. (3) In gas analysis, the additional carrier gas added upstream of the detector to achieve optimal flow

Gas, which meets the purchaser's specifications.

Any of a series of compounds of the general formula RSH, analogous to the alcohols and phenols, but containing sulfur in place of oxygen. "R" in the formula above represents the hydrocarbon radical. I.e., methyl-, ethyl-, propyl-, etc.

The lightest member of the aliphatic hydrocarbon series, with a chemical formula of CH4.

The lightest alcohol, having the chemical formula CH3OH.

Vessel internals which remove free liquid from gas.
