Production and Test Separator

Production and Test Separator

Well fluid streams originating from wellheads consist of crude gas, oil, condensate, associated produced water and several other contaminants. The primary purpose of the Production Separators is to facilitate the bulk separation of gas and produced water from the crude oil prior to further processing. Production Separators are critical for any upstream oil and gas processing facility as they have a significant impact on the operation of downstream equipment.

Process Description

Production Separators are used for bulk separation of the gas from the crude and water in the incoming well fluid stream for production. These are high efficiency gas/liquid or gas/liquid/liquid removal units designed to handle a wide range of flow rates, including liquid slugs. Depending upon the GLR (Gas to Liquid ratio), available space and transportation limitations, the separators can be designed with vertical or horizontal configuration. In general, horizontal, and vertical separators are preferred for low and high GLR respectively.

Production separators are designed for retention times of 1 to 10 minutes in the separation compartment depending upon the crude oil properties. Peerless can design separators to achieve gas outlet performance of 0.1 US Gal/ MMSCFD (99.9% removal of liquid droplets of sizes > 8µm), water in oil of 2–5% PPM and oil in water of 500–1000 PPM. However, this can be customized based on specific customer requirements.

Test Separators are used to facilitate the periodic testing of one or more wells by separation of gas, crude oil and water from well fluid stream for detailed flow measurement and analysis.
