Each mud gas separator has limitation on much it can safely handle volume of gas. If the volume of gas exceeds the maximum limit, gas can blow through into the rig. It is very important that you must estimate gas flow rate on surface based on pit gain and kill rate in order to see how much expected gas on surface. This will be the limitation on how much you can circulate for well killing operation. You can estimate the volume gas on surface by using well control kill sheet provided by several companies. You need to ensure that the vent line should be as straight as possible with a larger ID in order to minimize back pressure while venting the gas out.

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).

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.

DC solid control uses 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 separator is designed to remove gas from the mud/fluid before it is transferred to the shale shaker system. It separates gas out of the mud after the gas comes out of hole.

The mud gas separator is strictly used for well control only. There are some events that this equipment is utilized in a well testing operation. Additionally, inspection for the gas buster must be performed frequently the same as other well control equipment.

Vacuum degasser is a rugged vacuum unit designed to safely and efficiently remove 99.9% of entrained air and gasses such as methane, H2S and CO2 from drilling fluids. Designed for the rigors of field use, the unit features a 5 hp, 50 or 60 Hz industrial-grade TEXP motor rated for continuous operation.

vacuum degasser

Vacuum degasser utilize negative pressure by vacuum pump to withdraw entrained gases from the mud. In order for this to work, mud is pumped through a venturi, which develops a negative pressure in the vessel by vacuum pump, thus sucking mud into the unit. The choice between horizontally- or vertically-mounted units is typically based on the footprint requirements of the specific rig.

Drilling fluid gas-liquid separator is the first stage professional equipment to treat the gas invade mud. It is mainly used to remove the big bubbles with the diameter of about ≥Φ3mm.Most of these bubbles are the expanded gas filled in the drilling fluid in annular of wellbore. It would cause well kick if mot to remove it timely.

Operation principle

Drilling fluid with gas invades goes into the separator at the import tangentially and drops to a series baffles along the inner wall. After collision to increasing the contact area, It flows downward and become to a turbulent state which makes gas separate from mud and the free gas passes through the top of tank and discharged from the gas export. The length of gas export pipe can be determined at site and be induced to the safe place. The drilling fluid without gas will flow into the circular tank.

How to install

Generally, the mud gas separator is installed on the surface next to the 1# tank. The surface should be flat and stable.
The main body is lifted vertically to the surface by crane at the auriculars on the top of main body and then put down slowly. Three places on the top of the main body are pulled tightly by the steel string to assure the main body to be vertical to the surface.
After installation, Exhaust line the 2# channel 60-80mm distance of the mouth of a well.(The line is oneself, if needed to manufacturer provide, explain away to the speak for).Connecting the 3# import to the rotary prevention or throttle conduit and close the 4#waste export, open the 7#mud export and connect to 1# mud tank by the pipe.

When in moving, disassemble the pipe and loose the tightened string. Lift the top of the main body to make the auricular plane by crane. The ladder can be used as bracket in this situation.

After we send the new specification to the clients who are very satisfied with our design and advanced technology. After 15 days, the mud gas separator have alerady finished and prepared to delivery. Below is the pictures.

Why use mud gas separator

ZYQ series Mud gas separator(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. Mud gas Separator can be used to ensure the drilling process smooth.

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.

From above we know that, mud gas separator is the key equipment to ensure drilling safety. DC Solid control is a professional manufacturer of mud gas separator, we have ability and advanced technology to design any model equipment according to clients need, so if you have requirement of solid control equipment, welcome to consult us, believe we can provide the best design scheme for you.

Liquid gas separator process applied in variety industrial place are based on “Gravity settling”, “Impingement” and “Centrifugation, mechanisms.  Sometimes, they use either one or a combination of them and also” Filtration. As for a general rule, mechanical separation happened when the phases are not miscible and have different densities.

In momentum separation, fluid phases with different densities and have different momentum. Due to change of a two phase stream direction suddenly, the heavy phase of liquid( greater momentum) separated from the loght fluid. Gravity separation when occurs that liquid droplets settle out of a gas phase and the gravitational force of the droplet is greater than the drag force of the gas flowing around the droplet. Also in filtration, a fluid-solid or liquid-gas mixture will pass through a porous barrier which traps most of the solid or liquid particulates contained in the mixture.

The vertical gas-liquid separators are one of the fixed process equipment. This article attempts to five methods of two-phase separator design. Two phase separators can employ either vertically or horizontally. Im some cases, sometimes, separators may be having inlet diverters or designed with or without mist eliminator pads.

Why choose vertical gas-liquid separators:

1 The gas-liquid ratio is high.
2 A smaller plan area is required( critical on offshore platforms)
3 Easier solids removal.
4 Liquid removal efficiency doesn’t vary with liquid level.
5 Vessel volume is generally smaller.
