Drilling fluid mud gas separator is a special equipment of gas cut drilling fluid primary degassing, it is mainly used to eliminate the bubbles which the diameter is about 3-25mm.

The big bubbles is aiming at the expansion gas which is fully the borehole, if it is not eliminated, it will causes the well kick even spurt the surface of drill plate. The equipment uses the prevent sulfur material and adapts the gas with H2s processing.


Installation and maintenance


It is installed ground side of the circulation tank, use steel wire ropes fixed gas liquid separator with the ground.


1Before using, we should check the bottom buffer baffle, if attrition more than 10mm, it must be replaced the two baffles at the same time.
2After using we should keep the separator empty and open the washing month and clean it.

DC Solid control is a professional manufacturer of solid control equipment. We can supply all kinds of mud gas separator such as DCZYQ800, DCZYQ1000, DCZYQ1200.

DCZYQ series mud gas separator is special equipment to treat the gas invade mud in oil & gas drilling. When the gas invades drilling mud, the proportion of mud density and viscosity have a greater deviation, which can`t meet the requirement of drilling. If not treat it timely, the serious situation-blowout will occur.

Structure of ZYQ Mud gas separator

ZYQ series Mud gas Separator combined with the Electric Ignition Device can be used to ensure the drilling process smooth. It is devided into the normal pressure Mud gas separator and pressure auto-control Mud gas separator, according to the pressure.Mud gas Separator is your best choice to prevent drilling mud invasion.

Features and Benefits of Mud Gas Separator

1. Material: SS304 or Q345 from TangSteel for body .
2. The whole body: The mud gas separator with the process of the grinding, sand blasting,the 3 layers of painting: epoxy zinc painting as the primer, the epoxy painting as the middle coating, and the polyurethane for the final painting.
3. Separates and discharges the enormous free gas from drilling fluids, including poisonous gases like H2S.
4. Separated gas is carried by discharge lines to a safe area for combustion.
5. The unit is ruggedly built and coated with anti-corrosion epoxy so as to ensure long service life when processing hazardous and toxic gases.

Mud gas Separators is an extremely reliable, vital piece of safety equipment for today’s drilling operations. It is ideal for use where drilling is likely to encounter large volumes of gas, sour gas or when an operator is drilling with an under balanced mud column. This Mud gas Separators is primarily used to separate and safely vent large pockets of free gas, that may include toxic gases such as hydrogen sulfide, etc. from the drilling fluids processing system.

Mud gas separator is also called Poorboy degasser or liquid gas separator which is a common safety device in oil and gas drilling mud circulation system. The purpose of a separator is to separate free gas or mixed gas and oil from the drilling fluid and convey the gas or oil to a flare or holding tank.

Mud-gas Separator handles a high proportion of mud solids and may experience hydrate plugging as a result of gas expansion through choke. Design of our Mud Gas Separator is based on conventional process practice, involving a liquid seal system matched to an adequate gas vent.

Specification of mud gas separator
Temperature range : -40°C TO 75°C
Pressure rating : UP TO 15 BAR
Venting size : UP TO 12″
Outlet size : UP TO 10″
Dimension: Based on rig requirements.
Capacity inlet pipe (MIN/IN) : UP TO 125/5

DC Solid control supply both vertical or horizontal Mud gas separator and fitted with internal baffles and distribution nozzles but performance of the liquid seal is independent of these design features.

Mud gas separator is designed primarily for the removal of entrained gas, from the drilling fluid. The mud gas separator is designed in multiple capacities, to meet specific mud gas needs. But what should we pay attention to when use the mud gas separator.


Two situations can cause mud gas separator blow-through.

1. Friction pressure of the gas venting through the vent line exceeds the mud-leg hydrostatic pressure, resulting in evacuation of fluid from the separator. Friction pressure of the mud through the mud return line is considered negligible because of its short length.

2. Vessel ID is too small, causing insufficient retention time for the gas to separate efficiently from the mud. This situation is commonly called insufficient separator cut.

To estimate a peak gas flow rate properly, we must consider a “typical” kick. The typical kick will depend on the well location, depth, type size, and component ratios of influx. Kick data should be based on previous offset well data and should be a realistic worst-case gas kick.
