How to works of vacuum degasser

Vacuum degassing is the process of removing dissolved gas from a liquid solution by lowering the pressure inside a vessel containing the solution. The reduced pressure inside the vessel 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. This process is typically performed in a specially designed chamber known as a vacuum degasser. Vacuum degassing is often utilized in water treatment, laboratory testing, and soil purification procedures.

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.

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.

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 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.

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.

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.

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.

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.

Vacuum degasser can wipe off the invaded gas from drilling mud quickly, restore drilling mud proportion, keep mud viscosity performance and improve the quality of drilling fluid.

Vacuum degasser is very important for returning mud gravity, stabilizing mud viscosity and reducing drilling cost. Therefore, it works as one type mud cleaning equipment. As it is placed after the shale shaker, so we call it second stage mud cleaning equipment in mud recycling system.
