Importance of use vacuum degasser in oilfield

⋅ Leave a Comment

Degasser is used to eliminate the gas in gas cutting drilling fluid, its treating capacity should reach to full flow treating. Vacuum Degasser is must installed behind the shale shaker and before centrifugal pump.

So when drilling fluid obtain large gas, so the centrifugal pump will occurring cavitation, it not only make centrifugal pump performance is decrease, production voice and vibration and loss service life but also can make centrifugal pump can’t work or damaged.

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.

Working theory of vacuum degasser

⋅ Leave a Comment

Vacuum degasser is a special-purpose oil drilling fluids solids control equipment and a new type one for the drilling fluids system.
Vacuum Degasser 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, shale shakers and mud cleaners, while hydrocyclones and centrifuges follow in the
arrangement.

vacuum degasser

Vacuum degassers works 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. A high-vacuum process environment is maintained for a variety of product testing and laboratory applications.

This allows the user to analyze products or materials under a wide range of conditions and under predetermined atmospheric or environmental parameters. Some of the conditions that can be controlled by vacuum degassers include pressures. Some of the conditions that can be controlled by vacuum degassers include pressure and humidity, temperature, altitude simulation.

Vacuum degasser is only one of the solids control and waste management offered by DC Solid Control to the oil and gas industry. We also design and produce other solid control equipment, such as, shale shaker, desander, desilter, decanter centrifuge, mud agitator, centrifugal pump, mud pump and ect.

Corrosion explains Vacuum Degassing

⋅ Leave a Comment

During the production process, a product’s metal components can become infused with excess amounts of gases. As a result, unwanted imperfections and side effects can impact the integrity or performance of the metal.

Vacuum degassing processes involve the exposure of molten steel to a low-pressure environment to remove gases (chiefly hydrogen and oxygen). The effectiveness of any vacuum degassing operation depends upon the surface area of liquid metal that is exposed to low pressure. This process is typically performed in a specially designed chamber known as a vacuum degasser.

vacuum degasser

The reduced pressure inside the vessel or chamber causes the gas to become less soluble and separate from the liquefied material. After the vacuum degassing process is complete, the gas is removed from the vessel, and the pressure is returned to normal.

Vacuum degassing to remove carbon not only reduces imperfections, but also makes metals more ductile, or easily shaped and formed through cold metalworking.

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.

The function of vacuum degasser vacuum pump

⋅ Leave a Comment

There are mainly have two reasons why vacuum degasser use vacuum pump, the one is, the degassing mud in degasser absorb to the top of the degasser, make if form into thin layer flow on baffle, vertebral body or between hopper；The second one is the gas discharged in tank and intake air is all discharged. Vacuum pump also can produce a kind of pressure which can discharge the exhaust gas through a pipeline.

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.

The Spirovent Superior is a fully automatic vacuum degasser for heating, cooling and process installations. This device temporarily subjects part of the installation fluid to low pressure or vacuum. As a result, the air dissolved in the fluid is released and removed from the system. Thanks to the electronic, independent control system, reading system information is a breeze.

Why we can design the advanced vacuum degasser

⋅ Leave a Comment

Vacuum degasser use atmosphere and vacuum degassing theory eliminate the remaining gas in drilling fluid. Vacuum degasser tank is installed a group of wave blade and many mud inlet make flow is uniform distribution and form into turbulence in tank.

The throughput of vacuum degasser is 500g/m, 1200 type is 1200g/m, this is because the different area of wave blade. The blade area of vacuum degasser is 500 times of 500 type which is in order to ensure effective eliminate the remaining gas.

The vacuum tank produce low pressure in tank, the bubbles in the mud can well discharge. According the change of overload, vacuum pump proof motor can be adjusted. The mud liquid level in bottom tank feedback to a group of mechanical transmission device in order to automatic control inlet displacement and vacuum tank liquid level. Jet pump sucks out degassing mud from vacuum degasser tank.

Design characteristic

Drilling fluid enter into vacuum degasser from the inlet pipeline of tank wall. After gas is discharged from mud, flow to the bottom of vacuum tank. Degasser use vacuum and molecular collision / turbulence theory and maximize the surface area of drilling fluid to eliminate the gas.

Low pressure — the low pressure in vacuum tank make the bubble in mud is nature swell. It is more easy float to the surface of mud after bubbles is large and escaping mud.

Collision/ turbulence – the mud flow to the centre of tank and spray out from the ostioles which are in the wall of the tank. The liquid has enough force to impact the blade and tank wall. The result is the remaining gas is more easy escape to vacuum environment. The probability is big of blade is cracked.

Contacting area is maximum — in the process of mud splash to the tank from the odtioles in vertical pipe, the mud through a group of wave plate fine and thin blade make mud is disperse to increase the contacting area of the mud and vacuum environment. The residual gas is more easy to discharge.

Operation theory of vacuum degasser

Drilling fluid is transported to mud inlet from mud tank. Mud through degasser vacuum is bout 29inch of mercury is absorbed to vertical pipe. The mud splashes to wave blade and tank wall from the spray mouth of vertical pipe, the gas evolution this time and expose in the low pressure environment which is extracted by out tank vacuum pump.

The degassing mud ceaseless flow to bottom mud pit from blade group. Centrifugal pump is unceasing extract degassing mud by ejector.
