2. Sludge vacuum pump

GN Solids Control vacuum pump is a pneumatic pump with air as power source, which can be used to transport mine tailings, drilling waste, industrial slurry, chemical powder, construction aggregate, oil sludge, kitchen waste and other materials.

In the material conveying work, the screw conveyor is usually used for transmission, but because of the short conveying distance and high cost, the long-distance conveying demand cannot be well satisfied. The GN solid vacuum pump can reach a suction distance of 50 meters and a discharge distance of 1000 meters for clean water. It is of great significance for long-distance transportation.

The reason why GN Solids Control vacuum pump can have good effect and long head for solid conveying is because it can form high negative and positive pressure. GN Solids Control specially designed two types of vacuum pump rotary unloading device and vacuum pump buffer funnel to relieve pressure and prevent the impact in the process of discharging materials. So as to meet the requirements of customers.

This time, the sludge vacuum pump was supplied to a well-known environmental protection customer for material transportation, and a decanter centrifuge was used for solid-liquid separation, so as to meet the process requirements of the environmental protection company.

The GNMS-1500D trenchless mud purification unit consists of a GNZS707 double-layer shale shaker and two 16-inch desander cyclones, a compact mud tank and a centrifugal pump. The mud first passes through the lower coarse screen of the GNZS707 vibrating screen, and the separated solid phase is directly discharged from the vibrating screen. The liquid phase is collected by the mud tank below, and transported to the de-sanding cyclone by the centrifugal sand pump, and the liquid-phase mud is recovered and reused through the separation of the de-sanding cyclone. The solid phase falls to the upper layer of the vibrating screen for fine screening, and part of the mud is recovered again for the next cycle. The solid phase is directly discharged from the upper layer of the vibrating screen.

2. GNMS-1000D trenchless mud purification device

It is similar to GNMS-1500D trenchless mud purification device, GNMS-1000D consists of a GNZS705 double-layer vibrating screen and two 10-inch desander cyclones, compact mud tank, centrifugal sand pump. Its working principle is the same as GNMS-1500D.

The trenchless mud purification device plays an important role in the mud control on the trenchless site. They work continuously to provide clean mud for trenchless equipment

GN Solids Control has standard mud purification units and can also provide customized mud purification units according to customer needs.

Oily sludge treatment plants from GN Solids Control are mainly used to treat oily sludge from drilling platforms, refineries and tank bottoms. It is specially designed for the treatment of oily sludge with high viscosity and high solid content. After being separated by the treatment system, three products of oil, water and solid can be obtained.

Last week, GN Solids Control provided a customer in China with a complete set of oil sludge treatment equipment, model GNOST-15. Its main configuration includes:

1. Shale Shaker

The vibrating screen produced by GN Solids Control can separate larger solid particles from the diluted sludge. This system uses GNZS594F Shale Shaker, with 4 screens, large screening area, long screening time and good separation effect. The solid phase liquid content is low. At the same time, it has anti-splash. In order to prevent the material from adhering to the screen surface and causing poor screening effect, Shale Shaker is also equipped with a spray system, and the liquid phase after screening falls into the collection tank below. The matching Shaker Screen is also produced by GN Solids Control and conforms to the API RP 13C standard. It is not only used by many domestic companies, but also the screen mesh produced by GN Solids Control is often used in the vibrating screen of well-known foreign brands.

For more than ten years, GN Solids Control has been manufacturing decanters for handling drilling mud. In recent years, GN Solids Control decanters have been successfully used in drilling mud processing sites in many countries and regions. GN Solids Control decanters have gained a good reputation in performance. It has been successfully applied in both land drilling rigs and offshore drilling rigs. It can not only meet the tropical environment in the Middle East, but also meet the use in high-latitude and low-temperature environments.

    GN Solids Control Decanter Centrifuges range from 9″ drums to 30″ drums. The two high-speed centrifuges sold this time are GN Solids Control’s best-selling models in the oil drilling industry, 14-inch centrifuges: GNLW363.

1. High density solid phase separation centrifuge

Medium speed decanters are typically used for high density solids separation. The most commonly used high-density solid phase separation centrifuge is the GNLW452D series. For 18-inch centrifuges around 1800RPM, it is also commonly used in drilling mud barite recovery applications.

2. Low density solid separation centrifuge

In order to remove drilling mud China, the low density solid phase (LGS) which is harmful to drilling, GN Solids Control can provide high speed centrifuges at 3200RPM or above. In the rig solids control system for oil and gas drilling, a medium-speed centrifuge and a high-speed centrifuge are usually matched. Two frequency conversion centrifuges can also be used for more flexible speed adjustment to adapt to different drilling conditions.

3. Drilling waste treatment centrifuge

GN Solids Control can also provide complete drilling waste treatment systems, including decanter centrifuges and Vertical Cutting Dryer, Screw Conveyor, etc. Modular drilling waste treatment equipment or integrated skid-mounted systems can be provided according to customer needs.

In addition to oil and gas drilling mud centrifuges, GN Solids Control also provides drilling fluid shale shakers, complete solids control systems, oily sludge treatment systems and other popular products.

GN Solids Control is a solids control equipment manufacturer offering complete systems for solids control and drilling waste treatment equipment. Last month, GN Solids Control completed the fabrication of 5 sets of vacuum degasser for a Chinese drilling company. GN Solids Control can manufacture three main different types of deaerators including vacuum deaerators, centrifugal deaerators and liquid gas separators.

     For this drilling company, GN Solids Control supplies a vacuum degasser, model GNZCQ360B, with a maximum capacity of 360 m3/h of drilling mud, and GN Solids Control also produces a small vacuum degasser, model GNZCQ270A, with a capacity of 270 m3 /h.

Both vacuum degasser and centrifugal degasser are used to remove fine air bubbles, while liquid gas separators are mainly used to remove larger air bubbles. The vacuum deaerator is mainly placed in front of the desander or desilter, and is installed behind the drilling fluid shaker. The mud treated by the vacuum deaerator is pumped into the mud cleaner for treatment. The drilling fluid treated by vacuum degassing can prevent gas intrusion and control the density of drilling mud. It is of great benefit to the follow-up centrifugal pump and mud pump work. For users with small installation space, GN centrifugal deaerator can also be selected to meet the same function and reduce the floor space.

In addition to vacuum deaerators, GN Solids Control also manufactures liquid gas separators. Liquid-gas separators manufactured by GN Solids Control, also known as mud-gas separators, are installed with a large distribution plate that evenly strikes the drilling mud in the high-level pipeline, allowing the liquid to flow down with gravity and the gas to separate from the liquid and gas. The top of the device is drained to a non-hazardous area. Usually, according to the customer’s working conditions, dangerous gases such as H2S can be burned with the help of electronic ignition devices.

The 5 sets of vacuum degasser will soon be shipped to the customer’s well site. Previously, GN Solids Control also provided this customer with some other solids control equipment, such as drilling fluid shale shakers, decanters. With the most satisfactory work performance, and professional and timely after-sales service. Our customers give high praise to our company.
