Definition - What does Mud-Gas Separator mean?
A Mud-Gas Separator is a separator designed to continue drilling in underbalanced conditions with normal dramatic pressure surges. The separator is ideal for use in conditions where the drilling is expected to encounter large volumes of sour gas or gas. It is basically used to separate and carefully vent the large free gas pockets which are likely to contain toxic gases like hydrogen sulfide. In the KICK situation, the vessel separates gas and mud and allows it to move over the baffle plates. There are three types of vessels used in the Mud-Gas Separator – Open Bottom Type, Closed Bottom Type and Float Type; however, the principle of mud-gas separation remains same.
Petropedia explains Mud-Gas Separator
A Mud-Gas Separator is used primarily to remove entrained gas from the drilling fluid. The following features can be observed in the separator.
- Free gas is separated: The separator vents and separates the large pockets of free gas accumulations which include hydrogen sulfide from active mud system.
- Hazardous gas threats are reduced: The separated gas is then taken by the vent lines to a remote location and is flared.
- The rugged construction: A unit is build and coated ruggedly with a corrosion-resistant epoxy which ensures the long life.
- Trailer and Skid mounted transportable: It simplifies the process of spotting, transport and installation.
- Configuration is Versatile: The separator can be used in the compact offshore or land configuration.
