Closed drain in a gas processing terminal is required to allow process vessels to be drained during maintenance; the system usually consists of a series of closed drains headers and a vessel. The closed drains is usually sized to take the largest inventory from the process trains and duty/standby pumps are provided for pumping the liquids back into the process train.

Industry standard modelling tool used in the oil and gas industry to for instance size the Initial flowline and pipelines.

Integrated Production Modelling spans many disciplines, integrating information from the reservoir, subsea, flowlines, pipelines, flow assurance, facilities and process engineering as well as costs, schedule, cash flow and economics.

IPM is a time and cost effective technique for assessing and optimising field concepts whether it is in the well count, the phasing of wells, the subsea configuration, process configuration, timing of compression and expert line sizing.

Terms relating to swing of gas. Packing is where flow rates of gas into a pipeline are greater than withdrawal rates, then at times of high demand for the gas the pressure in a pipeline is allowed to fall, leading to drafting, where rates into the pipeline are less than withdrawal
