GN ZCQ series Vacu-FLO degasser v.s.Swaco horizontal degasser

Swaco horizontal degasser and vertical degasser are all different with GN vacuum degasser both in structure and working principle.

Working principle of Swaco horizontal degasser

The return-flow, gas-cut mud is drawn into the tank through a vacuum created by the discharge jet and pump. The mud is then dispersed in a thin layer over a two-tier, baffle-plate system where the entrained gas, including H2S and corrosive oxygen, is recovered by the vacuum pump. The freed gas is then discharged at a safe distance from the drilling operation while the restored mud is returned to the active mud system.

Vacu-Flo degasser

Working principle of GN

Vacu-FLO degasser

The vacuum degasser 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 in the function of vacuum pump suction to a safe area due to the fluid collision and bubble separator. However, the mud will enter the drainage cavity forced by its self-weight and pass the rotator and discharge off the cylinder. In addition, drilling mud can enter the pump cylinder only through the suction pipe, and can’t be sucked in through the discharge pipe because the vacuum pump and the master motor are started simultaneously and the rotator connected to the motor will revolve at a high speed.

Features of GN vacuum degasser

l)  Skid-mounted design simplifies spotting and installation

2)Small footprint-69x34in.(1750x860mm)

3) Totally self-contained

4)  Corrosion-resistant, epoxy coated inside and out to ensure long life and minimum maintenance

5) More leaf surface area- The greater the effective surface area, the more efficiently gas is separated from the mud.

6) GN particular design- provide higher fluid impact and greater turbulence for faster gas removal. you do not need extra feeding pump, it saves a lot of money and place for clients.

The mud gas separator is used in a ‘kick’ situation to separate large volumes of free gas invaded in the drilling fluid.

 Function of Mud gas separator

 Mud gas separator also called poor boy degasser, Gus buster, which is designed to provide effective separation of the drilling mud and invaded gas from the well by venting the gas and returning the mud to the mud pits. Small amounts of entrained gas can then be handles by a

liquid gas separator

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.

 Mud leg height is an important parameter for the mud gas separator, you need to clear it during evaluation.

 What is Mud leg?

The mud leg in the separator is controlled by adjusting the fluid level in the mud tank or by moving the separat6or up or down within the tank. Mud tank height can restrict the maximum mud leg obtainable for open-bottom mud gas separator.

 Mud leg is an important part for mud gas separator, it is also called Fluid level. Fluids level is maintained in a float mud gas separator by a float/valve configuration. The float opens and closed a valve on the mud return line to maintain the mud leg level. Valves can be operated by manual linkage system connected from the float to the valve, or the valve can be air-operated with the rig air. Mud leg height can be controlled by adjusting the float assembly.

 There are some inherent problems in the use of float-type mud gas separators. The manual linkage separator has experienced problems with linkage failure resulting in improper opening or closing of the mud return line valve. Air-operated valves fail to function if rig air is lost, resulting in no control of fluid level within the separator. Mud-return-line valves are prone to plug with solids, preventing mud flow back to the mud pits.

 Gas Flow calculation is another important issue to evaluate the mud gas separator.  

Usually we need to calculate the following items.

Vacuum degasser and poor boy degasser is both are degasser in oilfield, there are some differences some maybe confused.

How do the two degasser works and the difference

This two pictures is the different work principle of the two digassers.

The left side is the vacuum degasser, and the right side is the mud gas separator(poor boy degasser).

The vacuum degasser suck the drilling mud and separated mud and gas by vacuum pump.

Our vacuum degasser operates on a “thin strata” principle. The drill mud enters the tank and forces it to flow and distributed to a layer of internal baffle plates engineered to allow the liquid inside the vacuum degasser to flow as thin film and is exposed to the vacuum within the vessel. This layer of mud allows the gas to escape or break out of the mud . The vacuum pump releases the gas and discharge it to the disposal line. Mud exits the vessel under the action of the venturi and is returned to the mud system.

The poor boy worked by the physical characters.

The GN MUD/GAS SEPARATOR (poor boy degasser) consists of a cylindrical pressure vessel in a fixed vertical position. Inside is a series of specially angled baffle plates, stepped from the top to the bottom. When contaminated mud is routed into the separator, it flows downward successively over each plate. During this process, the heads of entrained gases “break out.” The released gas is then carried by the vent lines to a remote location where it can be safely flared. Continue reading »

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.

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 »

Drilling mud vacuum tank degasser is one type of degasser in oil gas drilling fluids system.Another type of degasser is called Atmospheric Degasser.

Both of the vacuum degasser are devices that removes air or gases (methane, H2S, CO2 and others) from drilling fluids. 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.

Vacuum Tank Degasser

Vacuum Type is the most common form of degasser. It can be horizontal, vertical or round vessel. A vacuum action is created to pull in the gas cut mud. When the liquid enters the tank it will flow and be distributed to a layer of internal baffle plates designed for the mud to flow in thin laminar film and is exposed to a vacuum that forces the gas to escape and break out of the mud.The vacuum pump moves the escaping gas from the vessel discharging it to the rig’s flare or environmental control system.

Gas Buster is called also called vacuum degasser in oilfield drilling fluids gas separating.

Gas buster

A  Gas Buster is a simple separator vessel used to remove free or entrained gas from fluids circulated in the wellbore, such as mud used during drilling operations. The gas buster typically comprises a vessel containing a series of baffles with a liquid exit on the bottom and a gas-vent line at the top of the vessel.

GN oilfield Gas Buster

Our oilfield Gas Buster operates on a “thin strata” principle. The drill mud enters the tank and forces it to flow and distributed to a layer of internal baffle plates engineered to allow the liquid inside the oilfield Gas Buster to flow as thin film and is exposed to the vacuum within the vessel. This layer of mud allows the gas to escape or break out of the mud . The vacuum pump releases the gas and discharge it to the disposal line. Mud exits the vessel under the action of the venturi and is returned to the mud system.

GN Gas Buster operates in three functions – mud circulation, vacuum creation and gas removal.  The Gas Buster  is used to remove the small entrained gas bubbles left in the mud by the mud/gas separator. These units are positioned downstream from mud/gas separators, gumbo removal equipments (if utilized), shale shakers and mud conditioners (if utilized), while hydrocyclone desander and Decanting centrifuges follow in the arrangement.
