Re-placed the order of 3 sets vacuum degasser for my Russian cooperator

This morning, DC machinery delivery 3 sets ZCQ270 vacuum degasser to our old cooperator in Russian. The 3 sets vacuum degasser are respectively used in 3 sets drill rig site in different areas.

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.

degassing equipment

Vacuum degasser uses vacuum to release free and dissolved gas in water, and then discharge them through the automatic exhaust valve system. At the same time, the degassed water will be injected into system.  This low gas content water is not saturated with highly absorbent for gas, it will absorb the gas in the system to achieve the gas water balance. Vacuum degassing machine repeats this cycle every 20~30 seconds. This movement in circles removes all the gas in the system.

Vacuum degasser produced by DC Machinery is suitable for various supporting of drilling mud solids control system, it plays an important role in restoring drilling mud performance, and can also be an agitator with big power.

DCZCQ Vacuum degasser test before shipping abroad

Vacuum degassing is a technique of removing dissolved gas from a liquid solution by lowering the pressure inside a vessel containing the solution.

This month, DC Machinery manufactures a ZCQ270 Vacuum degasser for a foreign clients used for oil& gas drilling field, and now the vacuum degasser is testing before delivery.‘

vacuum degasser

According to 2 day test, the DCZCQ270 vacuum degasser is qualified to leave factory. DC Machinery can produce four models vacuum degasser, ZCQ240, ZCQ27., ZCQ300 and ZCQ360. If you have special requirements of it, please contact us.

Function of degasser used for drilling fluid cleaning system

Degasser is used to eliminate the gas in gas cutting drilling fluid, its treating capacity should reach to full flow treating.
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 function of degasser have two; the one is ensure drilling fluid performance is stabilize, preventing blowout and well kick accident and ensure drilling safety.

The other one is ensure hydrocyclone can regular work. When drill middle and deep well, gas well and gas oil well must be matched vacuum degasser.

There are two types of degasser, one is atmosphere. The other one is vacuum type. Viewing from degassing mechanism, when drilling fluid is agitated by mechanical, vacuum draw and forming lamina turbulence, the gas can escape. Vacuum degasser has two functions of vacuum pumping and lamina turbulence, but atmospheric type degasser only has mechanical agitating. Viewing from degassing effect, vacuum degasser is superior to atmospheric degasser.

Drilling fluid vacuum degasser of Chiese famous manufacturer

Vacuum Degasser is a high-efficiency in-line module that removes dissolved gasses from drilling fluid. Its unique design assures reliable continuous operation and the highest level of continuous performance available without the need for helium degassing.

Working priciple of vacuum degasser

Vacuum degasser is vertical type degasser. It consists of vessel, base, vacuum pump, gear box, internal blade.Basic principle is degasser adopts water circle vacuum pump. Based on vacuum gas or negative pressure the gas buster will remove harmful air rapidly. It is very necessary device in oil and gas drilling, explore well, unbalance drilling. Adaptable for various well drilling fluid purification system.

Function of vacuum degasser

Drilling mud vacuum degasser is very important for returning mud gravity, stabilizing mud viscosity and reducing drilling cost. Also, at the same time oilfield vacuum degassing machine can be used as a heavy-power agitator and supported applicable to all types of drilling mud purification system.

DC Solid control as the professional vacuum degasser manufacturer in China, our vacuum degasser has won a popular praise in domestic marketing. With the confidence of hi-quality and best after sale service, we believe we can provide more hi-quality guaranteed solid control equipment to all over the word, of course, vacuum degasser is the one among them.

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.

Benefit of use vacuum degasser

ZCQ series Vacuum Degasser is a special-purpose device and a new type one for the treatment of gas in the drilling fluids. Also, at the same time vacuum degasser can be used as a heavy-power agitator and supported applicable to all types of mud circulation purification system.

Main function of vacuum degasser

Vacuum degassing is a technique of removing dissolved gas from a liquid solution by lowering the pressure inside a vessel containing the solution.

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.

These units are positioned downstream from mud gas separators, gumbo removal equipment (if utilized), shale shakers and mud conditioners (if utilized), while hydrocyclone desander and Decanting centrifuges follow in the arrangement.

Solvent of vacuum degasser

Degassing, an important step in the preparation of high performance liquid chromatography mobile phases, is used to remove dissolved atmospheric gases from drilling fluid which may interfere with the normal operation of the pump and detector.

Bubbles that from when these gases come out of solution may result in loss of pump prime and other irregularities, such as inaccurate and irreproducible flow, ultimately resulting in inconsistent retention retention times and noisy or drifting chromatograpgic baselines.

A bubble in the detector’s flow cell typically manifests itself as a “spike” which may hinder peak detection and integration. Dissolved oxygen poses special problems such as baseline shifts caused by the formation of ultraviolet absorbing oxygen -solvent complexes and diminished fluorescence response.

Applying a vacuum for several minutes to a solvent reservoir is an inexpensive, effective method of degassing. It is typically performed with a side-arm filtration flask and a vacuum aspirator attached to a laboratory faucet. Alternatively, a vacuum pump may be used. Care must be taken when empoying vacuum degassing. because it is an off-line, noncontinuous process, its long-term effectiveness is limited, as air will begin to redissolve as soon as the vacuum is removed. Complete resaturation of the mobile phase will occur within several hours. It is most effective when used on premixed solvents for isocratic separations and is generally unacceptable when performing gradient separation with a low-pressure solvent proportioning device.

In addition, vigorous vacuum degassing may alter the composition of mixed solutions as the more volatil;e organic components are selectively evaporated. This may lead to variablity in the retention times of separations performed with different batches of mobile phase.
