As a part of rig package, mud system is a separate but an essential part, the handling of drilling fluids can save huge cost of drilling. In the early oil industry open earthen pits were used as settling area to separate solids and mud thereby acting as a solids control equipment.

Now, with the stringent environmental regulations and high mud costs, the economics of an effective mud system come into consideration. Different solids control companies introduce zero-discharge systems, closed-loop systems, “quick move” technology, screening technology, disposal options etc. No reserve-mud pit is used in a truly closed mud system. Mud is continually processed primarily by mechanical means, such as screening, hydrocyclone and centrifuging to remove solids initially. A second stage to remove colloidal solids is by wastewater cleanup techniques.

Major components of a mud system, including:

Mud gas separator, flare ignition device

Shale shaker, mud cleaner(or desander, desilter), vacuum degasser, decanter centrifuge , centrifugal pump, mud hopper,  mud agitator, mud gun, mud tank and others, such as cutting dryer, screw auger, mud cooling unit,etc.

GN has 6 units of Vavc-Flo degassers in stock, their specs as below:

Model: GNCQ270

vacu-flo degasser

vacu-flo degasser

Flow Rate:1200gpm

Total power: 22+3KW

Dimension:2000 length x 1000 width x 1670mm height


All of them are brand new and with electricity 440V/60HZ, 3 phase, explosion proof. We can change the voltage according to your requirement.

GNCQ270 Vacu-Flo degasser V.S. Derrick Vacu-Flo 1200

Their flow rate is same, just the dimension and weight is different. The most different is that GNCQ270 vaco-flo degasser do not need feeding pump.

Vacu-Flo Degasser normally called vacuum degasser. It uses the suction of the vacuum pump to establish an under balanced pressure area in the vacuum cylinder and causes the drilling fluid into the hollow shaft of the rotator through suction pipe under the atmosphere pressure, and then lets the fluid spray to the walls of the cylinder from the windows on the hollow shaft, now the gas bubble cut in the mud may break and run off Continue reading »

Horizontal vacuum degasseris the most common degasser applied at present. A degasser is used in drilling to remove gases from drilling fluid which could otherwise form bubbles. It can remove virtually all entrained gases, including hydrogen sulfide and corrosive oxygen, from drilling fluid and reduce the threat of dangerous and costly blowouts while restoring mud to its original density for reuse in the active mud system.



GN standard ZCQ270 & ZCQ360 can process up to 1200gpm & 1500gpm, for requirement of processing rate less than 1000gpm, ZCQ270 will be your best choice.

2 Self-Contained, do not need a centrifugal pump for feeding

3 Simple operation

For small amount of entrained gas in a drilling fluid, the degasser can play a major role of removing small bubbles that a liquid film has enveloped and entrapped. In order for it to be released and break out the air and gas such as methane, H2S and CO2 from the mud to the surface, the drilling fluid must pass degassing technique and it can be accomplished by the equipment called degasser which is also a major part of a mud systems.

GN produce centrifugal pump for VACUFLO vacuum degasser, usually it is installed on the skid of the mud tank,together with the feeding pump of desander&desilter. The flow rate various from 20m3/h ~400m3/h.

Firstly, we should introduceVACUFLO vacuum degasser briefly.

 Function of vacuum degasserAn efficient degasser is essential to safe and productive drilling operations. Gas present in the well bore can reduce the hydrostatic head in the well bore – with the potential for even greater gas influx and possible blow-out.

How do vacuum degasser work?

Vacuum degassers work by creating lower pressure inside a vessel so air or other gaseous impurities can be removed from a substance, such as water or even molten steel. The air is siphoned from the vessel after pressure is lowered enough to force the gas from the substance.

Features of Derrick VACUFLO vacuum degasser

Derrick’s Design

More Leaf Surface Area

Corrugated Fiberglass Leaves

Gas Extraction

Large Access Door

Compared with Derrick VACUFLO vacuum degasser, GN vacuum degasser has the following features.

1 Smaller area required

Because of different design, GN Vacuum dgasser do not a feeding pump, it is a self priming one, so you save a lot of area to install the feeding pump of vacuum degasser.GN vacuum degasser have a compact structure which can be installed on the tank easily.

There are two kinds of degasser in oil gas drilling solids control equipments, one is vacuum degasser i.e. centrifugal degasser, the other is mud gas separation i.e. poor boy degasser.

The centrifuge degasser works using the principal of centrifugal force to separate gas from drilling mud. The device passes a gas-cut material throough a centrifugal force field to accomplish the degassing. The degasser contemplates the slurry flowing through the degasser by entering it through the top and flowing downward or entering from the bottom and flowing upward. In either case the slurry moves through the force field to accelerate gravity settling of the continuous phase of the flowable material and to accelerate buoyant force gas bubble rising time.centrifugal degasser

ZCQ Degassers provide effective degassing with high throughput by means of a unique centrifugal Vacuum design.

ZCQ Degassers are capable of handling high viscosity 20 pound mud with a 50% gas cut. They can draw up to 800 gpm and discharge as much as 400 gpm.

The ZCQ Degassing system is totally selfcontained on one skid. No auxiliary pump is required. Both suction and discharge are powered by a built-in Electric motor. Continue reading »

Oilfield drilling Poor boy degasser that removes air or gases (methane, H2S, CO2 and others) from drilling liquids. There are two generic types that work by both expanding the size of the gas bubbles entrained in the mud (by pulling a vacuum on the mud) and by increasing the surface area available to the mud so that bubbles escape (through the use of various cascading baffle plates). If the gas content in the mud is high, a mud gas separator or “poor boy degasser” is used, because it has a higher capacity than standard degassers and routes the evolved gases away from the rig to a flaring area complete with an ignition source.

State International Engineering can design and manufacture mud gas separators, either as standalone units or supplied with choke and kill manifolds.It is used before shale shakers.

Based upon your predicted operating conditions and your required gas handling capacity we will be able to calculate the optimal size of your mud gas separator. All our mud gas separators are supplied with a complete calculation package; this will include mechanical strength calculations, theoretical separation capacities and safe working pressures etc.

All State’s poor boy degassers are fabricated to ASME VIII div 1 or PD 5500. The vessels are then hydrostatically tested with a 3rd party classification society witness. Our mud gas separators are supplied with a product certificate and design review.

State International Engineering poor boy degasser are supplied with top quality temperature and pressure sensing equipment where requested. These instruments can provide local displays at the separator, a display at the choke and kill control system and give repeated signals for the drilling control system. State can also provide loop seal pressure monitors and alarms. All this can be achieved through an State Int. Eng. hazardous area certified, control system.

Oilfield drilling Poor Boy degasser is professional equipment to treat the gas invade mud. When the drilling mud result gas invade, the proportion of its weight and viscosity have a greater deviation not to meet the requirements of drilling. The serious situation is that would cause Chung well, and even blowout accident occurred, if not to treat it timely. ZYQ series Gas-liquid Separator combined with the (Company site: Solids Control System

Electric Ignition Device can be used to ensure the drilling process smooth. It is devided into the normal pressure gas-liquid separator and pressure auto-control gas-liquid separator, according to the pressure.Ga-Liquid Separator is your best choice to prevent drilling fluids invasion.
