Special degassing equipment- vacuum degasser

⋅ Leave a Comment

Vacuum degasser is a important degassing equipment in solid control system which remove the gases such as hydrogen sulfide, carbon  dioxide and natural gas from the drilling mud before they reach the shale shakers.

A suitable vacuum area will form in the top part of degassing compartment during degasser working and the mud will flow into the degassing tank fluently. Following is the introduction of vacuum degasser working principle.

Vacuum_Degasser

Operation principle of vacuum degasser :

The drilled cuttings would settle into the setting pit, and the drilling fluids would flow over and into the second compartment.  A sand pump would be used to pump the drilling mud from the second compartment up to the vacuum degasser,The drilling mud enters into the vacuum tank through the feeding pipe, and rotates by the rotor of the degasser, by the effect of centrifugal force, the drilling fluids would be threw to the inner wall of the vacuum tank, and the gases that migrate into the mud would be separated from the mud.

An in-depth study of drilling vacuum degasser

⋅ Leave a Comment

Vacuum Degasser is adapted to get rid of various cut-in gases in the drilling fluids. Vacuum degasser is very important for returning mud gravity, stabilizing mud viscosity and reducing drilling cost.

Gasses can be released from the fluid and removed from the installation in two ways:

1. Thermal degassing
Because of temperature differences in an installation, dissolved gasses are released automatically. By means of so called in line deaerators, the released gasses can be removed from the fluid.  Spirotech offers various solutions for this.

Vacuum_Degasse

2. Vacuum degassing
In case of vacuum degassing part of the installation fluid is temporarily put in an underpressure (vacuum) condition. The gasses dissolved in the fluid are released, separated and removed from the installation. The degassed, absorptive, fluid is returned into the installation and can absorb any present free gasses again. By repeating this process continuously almost all gasses will be released and removed. The fluid will now be undersaturated to such an extent, that no gasses will bereleased anywhere in the installation, so the problems mentioned before will not occur. Problems in places with a low flow velocity and a low overpressure are also solved in this way.

vacuum degasser

When to apply a vacuum degasser?

• When an installation contains many branches, with a low flow velocity. In this case, the free, accumulated gasses will hardly be carried away with the flow, but will
disappear slowly thanks to the fluid being made absorptive.

• In case of small temperature differences only a small amount of gas is released by the heating or cooling process, which can be removed by an in line deaerator. A vacuum degasser works independent of the fluid temperature.

• When an in line deaerator cannot be mounted for practical reasons. A vacuum degasser can be mounted at almost any place in an installation.

Advantages of using DCZCQ Vacuum degasser

⋅ Leave a Comment

Vacuum Degasser are 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, shale shakers and mud cleaners, while hydrocyclones and centrifuges follow in the arrangement.

Working principle of vacuum degasser

The degassers are used to clean the gas in the drilling fluid, to ensure the drilling fluid property relatively stable, to guarantee the steady operation of swirlers. The degassers can be grouped into two kinds: ordinary pressure type and vacuum type. The ordinary pressure degasser is to use the centrifugal to take out gas to invade the mud, with the help of centrifugal force to make the mud spraying in the jet tanks and striking on the wall to make gas releasing. The vacuum degasser is to use the suction of the centrifugal, forming negative pressure in the vacuum tanks, under the action of drilling fluid at atmospheric pressure, through the suction pipe into the hollow shaft, then by umbrella piece of around the hollow shaft assembly, they jet to the skin of tank.

Structure of vacuum degasser

ZCQ vertical type vacuum degasser made of explosion proof motor, vacuum pump, coaxial shunting gear reducer. When works, pressuring the start key, motor drive vacuum pump and mud gas separator degassing impeller rotate, gas cut invaded drilling fluid absorbed to mud gas separator and throw to mud gas separator by degassing impeller. Production a fluid lamina which is eddy spiral movement and form the centrifugal force field. Because the centrifugal force is the 32 times of its gravity, make the small bubbles in fluid lamina rapidly buoyancy lift to surface, in the function of negative pressure, the small bubbles rapidly broken, the broken bubbles gas enter into vacuum pump and discharged through the two air holes in reducer.

Common hidden dangers and remedies of vacuum degassers

⋅ Leave a Comment

Vacuum degasser is the second stage solid control equipment, which is used when drill above 3000m well, so it is very important for drilling. And how to install it and what hidden dangers it has, please continue to look down.

Common hidden dangers in installing a vacuum degasser;

(1). The degasser is not connected with a flare line pipe, or the pipe is not at least 15m from the mud tank area.

(2). The relief pipe of the degasser shrinks in diameter ot is bent, so that the gas is not delivered smoothly.

(3). The relief pipe of the degasser is upright, releasing gas above the mud tank area.

vacuum degasser

1. Hazard:
The degasser is not installed with a relief pipe, pr the pipe connected outside the tank is less than 15m away. The gas discharged will accumulate in the tank area, casuing danger of explosion.

Remedy:
The relief pipe of the degasser is connected 15m beyond the tank area. The flammable pernicious gases can be ignited at the wellhead if necessary, the 15m relief pipe is connected beyond 15m when the degasser is used.

vacuum degasser1

2. Harden:
If the relief pipe of the degasser has a reduced diameter or is bent, it decreases the efficiency of removing gases.

Remedy:
The inside diameter of the relief pipe of the degasser should not be less than the open diameter of the outlet, and should open toward the road ahead. If the hose is used, it should not be deformed due to compression; a right angle bent should be used to turn a corner.

3. Hazard:
The relief pipe discharge directly above the tank area. Because the outlet of the pipe is about 3m above the surface of the tank, permicious gases cannot be ignited and set on fire. Inflammable pernicious gases will accumulate around the tank area.

Remedy:
The relief pipe of the degasser is connected 15m beyond the tank area. Inflammable pernicious gases can burn at the outlet when released.

The special equipment- Vacuum Degasser

⋅ Leave a Comment

A vessel into which drilling mud is pumped to remove gas entrained in the drilling mud. Modern, compact degassers use three commonly recognized methods of degassification: centrifugal force, turbulence, and vacuum, See degassing drilling Mud.

Degassing drilling mud

An important part of well-drilling operations is keeping the drilling mud free of entrained gas, or bubbles that enter the mud as it circulates downhole throgh gaseous formations. One of the three functions of mud is to provide sufficient hydrostatic head to control a kick when high-pressure oil or gas is encountered.

SONY DSC

Vacuum Degasser Working theory:

When mud of a certain density is circulated, it can become infused with gas to an extent that, although the volume of mud may increase, the density is severely reduced. To guard against this dangerous situation, the mus is degassed at the surface. Several kinds of equipment get the gas out, but all have one aim in common: to make it possible for the gas bubbles to free themselves.

vacuum degasser

 

One method flows the mud over wide sheets so the slurry is no more than one-eight to three-eights thick and the bubbles may come to the surface and escape. Another method sprays the mud against a baffle in a spray tank that squeezes out the gas. A third method directs the mud through a vacuum tank where, under reduced atmospheric pressure, the bubbles of gas expand and break out of the slurry.

Working principle of DC vacuum 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.

vacuum degasser

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.

Difference on vacuum degasser and poor boy degasser fluid processing

Vacuum degasser usually used to separate less gas than poor boy degasser. Although they both are degassing devices. Poor boy degasser is set up before shale shaker in the oil and gas well drilling. Before fluid flowing to shale shaker it need to be processed by poor boy degasser for safety working condition. Especially when the well depth is more than 4KM.

What is drilling fluid vacuum degasser

⋅ Leave a Comment

The vacuum degasser is a high-efficiency in-line modele that removes dissolved gasses from HPLC solvents. Its unique design assure reliable continuous operation and the highest level of continuous performance available without the need for helium degassing. Up to five solvent lines may be degassed simultaneously by one unit. The extremely low internal volume of each teflon AF channel offers very quick equilibration and very short startup times compared with PTFE degassing channels which have the same degassing efficiency.

vacuum degasser

A vacuum is pulled on a stream of water, and the vacuum draws the dissolved gas out of solution, removing it from water. There are two basic systems available – tower and membrane. In a vacuum degasser tower, water flows by gravity down through a tower filled with packing as a vacuum is drawn on the tower. The packing in the tower has a very high surface area, disperses the water very effectively, thereby enhancing the removal of O2, CO2 and N2. Performance is further enhanced by using atomizing nozzles as the water enters the tower. In a membrane degasser, water flows across one side of a membrane surface while a vacuum is drawn on the other side. Both types of systems use steam jet eductors or liquid ring pumps to generate the vacuum required.

VACUUM DEGASSING PROCESSES :

Vacuum degassing is practiced in the steel industry for several purposes. They are :

to remove hydrogen
to improve cleanliness by removing part of the oxygen
to produce steel of low carbon content ( < 0.03%)
to produce steels to close chemical composition ranges (including deoxidizers), and
to control pouring temperatures, especially for continuous casting operations.
