As more and more countries start to control the drilling waste and improve the standard of waste discharge in oil and gas drilling field, drilling waste management becomes more and more popular and important. Many companies have to or want to start their business for drilling waste management. But many clients do not have experience on it. They do not know how to choose the suitable equipment or systems for their activities.

As a worldwide famous brand on mud solids control and drilling waste management, GN Solids Control start its research and development department for drilling waste management and industry waste management for many years. Below is a brief introduction of normal drilling waste management equipment to help the users make decision.

1) High G drying shaker.

It is also named High G dryer, cuttings dryer. It utilizes high G force up to 8.0G to dry the cuttings. If there are big particles in the solids waste, high G shaker is requested. It can remove big size solids and even metal particles. The high G shaker can remove solids above 100 microns.

It is mainly used to treat the water base mud and water based mud cuttings. It can also be used for oil based mud treatment in some cases.

When the high G drying shaker is used to treat oil based mud and cuttings, it can only reduce the oil on cuttings (OOC) to 10 ~ 15%.

2) Vertical cuttings dryer

It is also called vertical centrifuge or vortex dryer. It utilizes centrifugal force up to 420G to separate the fine solids and recovery the usable drilling fluids. The screen opening of VG dryer is 0.5mm, 0.35mm and 0.25mm. It cannot allow big size sizes solids or metal particles; otherwise, it will be broken.

Vertical cuttings dryer is mainly used for oil base mud and cuttings. It can reduce the oil on cuttings to 3 ~ 5%. In this case, the solids discharge is on a very dry condition and it is easy for shipment. And the solids with 3~5% OOC can be discharged directly in many countries. If not, it is also easy for next treatment.

3) High speed centrifuge and big bowl decanter centrifuge

It utilizes the high centrifugal force to separate the very fine solids to 2～5 microns. It is used after high G shaker and vertical cuttings dryer, for further separation.

There are many other equipment used for drilling waste management, we will introduce in next file.

The high pressure air wash pump is with air engine for high pressure. It is a kind of cleaning flush pump wilde used for shale shaker or drilling fludis mud systems.

Features of air powered high pressure wash pump

The air engine motor compresses air as power source. The air powered high pressure wash pump does not generate electric spark. It will not be overheating, or explosion. It is safe and without other risk factors the same with electrical driven pumps.
1) The air powered wash pump is with low speed pump
2) The pump, fitting parts and hoses are all made from anti-corrosive
3) It is 3 ea ceramic piston designs
4) The air powered high pressure pump is equipped with long life time sealing
and stainless steel valve
5) There is build-in by-pass valve and safety valve for the air powered high pressure wash down pump
6) No spark air drive air filter, regulator and lubricator
7) Build-in silence

Applications of air powered high pressure wash pump

It can be use as long-distance operation; It can meet the requirements of safety regulations. Especially for oil and gas drilling, petroleum and chemical field, coal and mining industry, flammable areas, explosive, high temperature, humidity, dust and other safety explosion-proof requirements conditions. It can also be used in emergency situations, like as emergency fire extinguishing.
There are wall-mounted type air pressure wash down pump and cart type wash down pump. The cart type is more popularly used in oil and gas drilling field, as it is compact design and easy for movement. It can flush for the oil field shale shaker and other screen separation machine, to avoid the screen from blocking. It can also do other cleaning up jobsite at the rig site, for the vertical cutting dryer, the mud tank systems, the decanter centrifuges, etc.... The air powered motor type is especially well suitable for the offshore drilling rig hazardous areas.
It has various applications when used in oil and gas drilling field. The
The air powered washer is specially designed for hazardous environment. It can working at gas environment and improves safety of cleaning works.
