Process Flow Diagram For Mud Gas Separator

Mud Gas Separator is commonly called a gas-buster or poor boy degasser. It captures and separates large volume of free gas within the drilling fluid. If there is a "KICK" situation, this vessel separates the mud and the gas by allowing it to flow over baffle plates. The gas then is forced to flow through a line and vent it to a flare. A "KICK" situation happens when the annular hydrostatic pressure in a drilling well temporarily (and usually relatively suddenly) falls below that of the formation, or pore, pressure in a permeable section downhole, and before control of the situation is lost.

It is always safe to design the mud/gas separator that will handle the maximum possible gas flow that can occur.[1][2]

Types of Mud/Gas Separators

The principle of mud/gas separation for different types of vessels is the same.[3]

  • Closed bottom type
  • Open bottom type
  • Float type

According to pedestal or base type there are

  • Fixed type
  • Elevating type

Poor boy degasser in China is usually named according to vessel diameter.So the type also including

  • FLQ800 or ZYQ800
  • FLQ1000
  • FLQ1200
  • FLQ1400

Usually, the degasser type or configuration is customizable

Principle of operation

The principle behind the mud gas separator is relatively simple. On the figure, the mud and gas mixture is fed at the inlet allowing it to impinge on a series of baffles designed to separate gas and mud. The free gas then is moved into the flare line to reduce the threat of toxic and hazardous gases and the mud then discharges to the shale shaker and to the tank.
