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 mud.For oil and gas well drilling, we usually set mud gas separator ahead of shale shakers. The drilling mud out of well bore will flow into degasser via the chock manifold.

DCZYQ Mud Gas Separator (Poor Boy Degasser) is engineered specifically for onshore drilling operations. The working principle of the poor boy degasser is simple. The drilling mud with gas mixture in the bore hole is transferred by mud return lines to the inlet of the mud gas separator, allowing it to impinge on a series of baffles which separates gas from drilling mud. The free gas flows into the flare line to be burned and the mud discharges to the shale shaker and to the mud tank.

DCZYQ series Mud gas Separator combined with the Electric Ignition Device can be used to ensure the security of drilling process. It is divided into the normal pressure Mud gas separator and pressure auto-control Mud gas separator according to the pressure.

The models of Mud gas separators we have are DCZYQ800 DCZYQ1000 and DCZYQ1200. Besides, there are three major types of mud gas separators :

1. Open bottom: These separators are often called “poor boys,” and immerse the bottom of the machine in the mud deposit.
2. Closed bottom: A closed bottom mud gas separator features a sealed base, which directs the mud return into the storage tank.
3. Float: The float design is similar to the closed bottom type of separator, except that it has a valve rather than a permanently sealed line for the mud return. Fixed or elevated pedestals are also used to mount the base.

The Mud/Gas Separator allows operators to circulate the drilling fluid by removing large pockets of gas. The gas cut mud enters the unit, where it hits a series of baffle plates. These baffle plates provide surface area for the dispersion of the gas cut mud.

The mud is routed to solids control equipment for further processing while the separated gas travels to the flare line at the top of the unit to be vented at a safe distance from the rig and rig personnel.

The mud/gas separator is designed to provide effective separation of the mud and gas circulated from the well by venting the gas and returning the mud to the mud pits. Small amounts of entrained gas can then be handled by a vacuum-type degasser located in the mud pits. The mud/gas separator controls gas cutting during kick situations, during drilling with significant drilled gas in the mud returns, or when trip gas is circulated up.

Three types of mud/gas separators commonly are used today: closed bottom, open bottom, and float type. The principle of mud/gas separation within each type of vessel is identical. Differences can be found in the method of maintaining the mud leg.

Commonly called the poor boy, the open-bottom mud/gas separator is typically mounted on a mud tank or trip tank with the bottom of the separator body submerged in the mud. The fluid level (mud leg) in the separator is controlled by adjusting the fluid level in the mud tank or by moving the separator up or down within the tank. Mud-tank height can restrict the maximum mud leg obtainable for open-bottom mud/gas separators.

DC use high quality steel materials manufacturing normal pressure prevent H2S Mud Gas Separator,can effectively prevent the harmful gas erosion, ensure the man- machine safety production. We provide 4 models of open-bottom mud/gas separator, such as DCZYQ600, DCZYQ800, DCZYQ1000 and DCZYQ1200. Please contact us if you have interest with it.

The height and diameter of a poorboy degasser separator are critical dimensions which affect the volume of gas and fluid the separator can efficiently handle.

As the mud and gas mixture enters the separator, the operating pressure is atmospheric plus pressure due to friction in the gas vent line. The vertical distance for the inlet to the static fluid level allows time for additional gas break-out and provides an allowance for the fluid to rise somewhat during the operation to overcome friction loss in the mud outlet lines.

Care should be taken to ensure minimum back pressure in the vent line,. On most offshore rigs, the vent line is extended straight up and supported to a derrick leg. The ideal line would be restricted to 30 ft in length and top of the line should be bent outward about 30 degrees to direct gas flow away from the rig floor. If it is intended that the gas should be flared, flame arresters should be installed at the discharge end of the vent line.

As stated previously, when the gas pressure in the separator exceeds the hydrostatic head of the mud in the U-tube, the fluid seal in the bottom is lost and gas starts flowing into the mud system. The mud outlet downstream of the U-tube should be designed to maintain a minimum vessel fluid level of approximately 3 1/2 ft in a 16 ft high separator.

Assuming a 9.8 ppg mud and total U-tube height of 10 ft the fluid seal would have a hydrostatic pressure equal to 5.096 psi. This points out the importance for providing a large diameter gas vent line with the fewest possible turns to minimise line frictional losses.

DC mud gas separators are designed to provide safe drilling procedures during horizontal, underbalanced, h2s, or high pressure drilling. Our gas buster captures and separates the mud/gas then safely vents free gas to the flare line to be burned off while returning mud to the mud pits.

Our Mud gas separators are intended to sustain safety for high pressure wells or when sour gas may be present. Our units are closed bottom skid mounted model designed around safety and precision. Uniquely designed baffles break up mud and gas which is then expelled by the gas vent line to the flare line.

DC Gas Busters have a 12” inlet from flow line, 12” gas vent line to flow line, 12” return line, and 20” manhole. If necessary these lines can be modified with flanged concentric reducers to your desired piping size. The run of the gas vent line continues to ground level for safe and efficient hook up to the flare line piping.

DC’s Mud Gas Separator has a lot of advantages including reliable safety, better treatment effect, long service life, etc. DC use high quality steel materials manufacturing normal pressure prevent H2S Mud Gas Separator,can effectively prevent the harmful gas erosion, ensure the man- machine safety production.

The mud gas separators should be able to handle a high proportion of mud solids and may experience hydrate plugging as a result of gas expansion through the choke. Designs based on conventional process practice, involving a float controlled liquid dump valve and a control valve to regulate gas pressure are not suitable because of the accentuated risk of malfunction due to plugging and the consequent need to provide a relief valve which itself may plug. Mud gas separator designs should therefore be based only on a liquid seal system matched to an adequate gas vent.

Liquid Throughputs

The volumetric flow capacity of the system should be based on an adequate gravitational rate from the mud gas separator. A typical liquid capacity of 6 barrels per minute of 12 pounds per gallons drilling fluid of average viscosity is a guide for vertical mud gas separator.

Liquid seal design

The liquid seal ensures that separated gas vents safely without breaking through to the mud tanks. The seal may be in the form of an external U-tube or may be based on a dip tube extending into a tank, usually the trip tank. The liquid seal hydrostatic pressure must be monitored against the back pressure of the gas vent line in the mud gas separator. It may be integrated as part of an instrumentation control system for the whole system.

Anti-Siphon Line

If the liquid seal is based on a U-tube design, an independent vent pipe, preferably 6 inches nominal diameter or larger, should be fitted at the highest point of the pipe work to avoid siphon effects and as a back-up to dispose of gas carried through the U tube liquid seal. The secondary vent need not extend to the top of the derrick. It should never be tied onto the primary vent.

Relief lines

All surface gas handling systems should have a means of diverting the flow from the choke and kill manifold through overboard relief lines and isolating the mud gas separator. In a blow-out situation, this may be the last resort to allow evacuation of personnel from the drilling rig. The pressure rating of the piping and valves on overboard lines should not be less than the pressure rating of the buffer
