ZCQ240 Vacuum degasser delivery to Pakistan

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.

DC Solid control shipped 3 sets ZCQ240 vacuum degasser to Pakistan drilling company which is a local government company who had already cooperated with our company for about 3 years.

vacuum degasser

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.

DC Solid control can provide you 4 models vacuum degasser, ZCQ240, ZCQ270, ZCQ300 and ZCQ360. If you have interesting with it, please feel free to contact me soon.

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.

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.

Why Use Vacuum Degasser in a Mud System?

An efficient degasser is essential to safe and productive drilling operations. Since gas is practically insoluble in water, it is relatively easy to detect and remove. By comparison, gas is readily soluble in oilbase muds – its detection is more difficult as well as its removal. Regardless of the composition of the gas encountered, gas present mud can decrease efficiencies in rig pumps, centrifugal pumps and associated operational equipment. The goal is to “Keep the pumps Operating”.

Atmospheric vs. Vacuum Degassers

Atmospheric separations rely on impact, turbulence, agitation or a combination of these techniques to separate gas from the fluid. They possess few moving parts and have low initial cost. But their efficiency is limited and they may not be suitable for all conditions.Vacuum Degasser

Vacuum degassers have more moving parts and higher initial cost. This is due primarily to the vacuum pump and attendant components. They are, however, much more efficient. Because gas volume is inversely proportional to pressure, gas bubbles surface from a fluid more rapidly under pressure. By combining impact and turbulence features with low pressure, modern vacuum degassers prove to be fast acting and highly effective in separating dissolved gasses.

 

How to match centrifuge and vacuum degasser

Yesterday I wrote the matching of  shale shaker, desander and desilter. In solid control system, drilling fluid centrifuge and vacuum degasser is also needed to be matched reasonably.

The choice of drilling fluid centrifuge

Drilling fluid centrifuge is the last level solid control equipment, mainly used for eliminate 2-10μm solid particles from drilling fluid. There are two types centrifuge: one is used for recycle barite from weighted drilling fluid, the treating fluid is the underflow of desilter; another is used for eliminate solid phase from non-weighted drilling fluid, the treating fluid is the overflow of desilter. 

Drilling fluid centrifuge mainly used for drilling deep well and superdeep well. It’s little significance to drill shallow well. Choosing suitable sand pump to match centrifuge is very important in use.

The match of vacuum degasser

Vacuum degasser is used for eliminate gas in the drilling fluid, the processing capacity should reach full flow dispose. Vacuum degasser must be installed after shale shaker but before sand pump. Because if the drilling fluid contains gas, centrifugal pump will occur to cavitation, the cavitation is not only reduce performance of drilling fluid sand pump, engender noise and vibration, reduce life, but also make the sand pump can’t work in serious.

The functions of vacuum degasser are two points: one is to ensure drilling fluid performance relative stability and to prevent the blowout, kick accident, ensure drilling safety; the second is to guarantee the swirler can work normally. In the drilling of deep exploration well, gas well and oil &gas well, must be equipped with vacuum degasser.

 

High quality drilling fluid vacuum degasser

Introduction of vacuum degasser

The degasser is used to clean up the gas in the drilling fluid, ensuring the performance of drilling fluid relatively stable and the proper functioning of swirler.  It is the second level equipment in solids control system, and it will be set between shale shaker and mud cleaner/desander.

The vacuum degasser is a high-efficiency in-line module that removes dissolved gases from HPLC solvents. Its unique design assures 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 volum of each Teflon AFchannle offers very quick equilibration and very short startup times compared with PTFE degassing channles which have the same degassing efficiency.

The work principle of vacuum degasser

The vacuum degasser uses the suction function of the vacuum pump to form the negative pressure in the vacuum tank. Under the pressure of atmosphere, the drilling fluid enters into hollow shaft from suction line, and then to be gathered by the umbrella slices around of the hollow shaft to toss to tank skin in spurting. With the impact of vacuum and bubble centrifuge, the bubble will be broken in the drilling fluid, the gas will escape and suction out by the vacuum pump and vent to the safety zone.

Introduction of DC 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. It can separate various gas in drilling fluid. Meanwhile, it will recover mud weight efficiently, keep drilling fluid property steady. Vacuum degasser also can be used as big mud agitator, and adaptable for various mud system.

ZCQ Vacuum Degasser is produced by DC Machinery and is one of the most important Equipments for Solids Control. The vacuum degasser design of the structure is scientific and rational. So we are able to achieve an effective gas-liquid separation, filter out impurities and to ensure that the exhaust pipe is always smooth.

ZCQ vacuum degasser has many features, which includes compact design, high performance/full vacuum, vacuum pump mounted together with degasser vessel, internal impellers, vertically-mounted units, without feed pump.
