The standard model of DC Oil Sludge Treatment Plant

⋅ Leave a Comment

Oil sludge is a mixture consisting of oil, water and solids. The treatment on oil sludge would recover much oil and water for reuse. Also it is an ideal solution to for the solids disposal. More oil and water recovered, more energy and resource could be saved. DC oil sludge treatment plant mainly include decanter centrifuge, oil water separators and thermal desorption unit.

Oily Sludge Treatment Process

The main technology we used to dispose of the oily sludge is pyrolysis. Let’s see the specific process of working,
1. Collect all of the oil sludge together and then unload them to the workshop. Most of our oily sludge pyrolysis plants are installed in the open air. And then use our auto screw feeder to feed them into the pyrolysis furnace.
2. Under an oxygen-free, high temperature and sealed environment, the three main components of oil sludge, oil, sludge, and water, will be decomposed.
3. When the temperature rises to a certain degree, oil gas will come out. Thereinto, heavy particles in the gas will be liquefied into heavy oil and then dropped into the heavy oil tank; light particles in the gas will rise up and liquefied into light oil in the horizontal tube condenser and then also be reserved in the oil tank.
4. The slag will be automatically collected during the process.

China vertical cutting dryer senior supplier

⋅ Leave a Comment

Vertical cuttings dryer could be regarded as a vertical centrifuge, and widely used to treat drilling cuttings in oil drilling field. ertical cutting dryers are one of the industry’s best performing and most dependable cutting dryers.

Vertical cutting dryers provides its operators an advantage for environmental and economic reasons. Vertical cuttings dryers are a necessity for industries where increased regulations on cuttings discharge are prevalent.

SONY DSC

Main function of vertical cutting dryer:

A vertical cuttings dryer can reduce liquid content to 5% with less maintenance costs. Vertical cutting dryers offer a waste management solution to effectively clean and dispose of drilling solids and maximize drilling fluid returns specific to operational needs.

Features：

1. The annular drain groove of the Cutting Dryer is installed at an oblique angle at 4°and the drain port is in the bottom of the groove. A vent is designed above the drain port. It’s helpful to discharge the viscous liquid when open the vent.
2. Wear-resistant material is adapted to those parts where may hit by the speeding solids come from the centrifuge. By doing this, we effectively prolong service life of relevant components.
3. Mechanical overload protection device would stop the vertical cutting dryer motor running whenever the torque is larger than rated.
4. Newly designed and unique structure of sludge discharge pipe and sludge collector makes sure the vertical centrifuge dropping and no jam.、

Vertical cutting dryer’s function of DC Solid control for drill cutting dispose

⋅ Leave a Comment

Vertical cutting dryer could be regarded as a vertical centrifuge, the discharged cuttings are transferred by the auger get into the Vertical cutting dryer from the opening on the top, under the function of centrifugal force produced by rotation of the screen module.

Vertical dryer can recover up to 95% of drilling fluids. A large decrease in attraction between liquid and oil results in a retort of vertical dryer cuttings that can range between 6% and 1% oil by weight.

Technology Descriptions of Drilling Waste Management

⋅ Leave a Comment

The first step in managing drilling wastes is to separate the solid cuttings from the liquid drilling mud. Once solid and liquid drilling wastes have been separated, companies can use a variety of technologies and practices to manage the wastes.

For some applications, drilling wastes are solidified or stabilized prior to their ultimate management practice. The management technologies and practices can be grouped into three major categories: waste minimization, recycle/reuse, and disposal. Follow the below introduction to learn more about the specific technologies and practices in each category.

Waste Minimization Issues

Waste minimization can be looked at strictly from the perspective of solid waste volume. A more comprehensive view of “minimization” looks at the overall environmental impacts associated with a process or technology. There are many relatively simple processes that can be used on drilling rigs to reduce the amount of mud that is discarded or spilled. Examples include pipe wipers, mud buckets, and vacuuming of spills on the rig floor.

Beneficial Reuse of Drilling Wastes

Most water-based muds (WBMs) are disposed of when the drilling job is finished. In contrast, many oil-based muds (OBMs) and synthetic-based muds (SBMs) are recycled when possible. Sometimes the physical and chemical properties of the used muds have degraded somewhat, and the muds must be processed to rejuvenate the necessary properties.There are many relatively simple processes that can be used on drilling rigs to capture clean mud that would otherwise be discarded and return it to use. Examples include pipe wipers, mud buckets, and vacuuming of spills on the rig floor. Recovery of mud during tank cleaning may also allow the mud to be reused. Solids control equipment, like centrifuges, can be used to remove solids from the recirculating mud stream.

Disposal

The use of earthen or lined pits is integral to drilling waste management. During most U.S. onshore drilling operations, the cuttings separated by the shale shaker are sent to a pit called the reserve pit located near the drill rig. The pit is generally open to the atmosphere, so it also accumulates stormwater and washwater from the rig.
