Water-based Mud zero discharge and oil-based Mud zero discharge

Oil-based Mud zero discharge mainly for directional wells and ultra-deep wells. Directional wells and ultra-deep wells require an oil-based mud system to prepare the mud. The oil-based mud contains expensive diesel or white oil, and the oil-based drilling solids control system treats the oil-based mud. If the drilling cuttings still contain oily mud, if the mud is not treated on the ground, the mud will be wasted and the drilling cost will increase.

Water-based Mud zero discharge mainly for shallow wells. Water-based mud is mainly prepared by adding chemicals or industrial salt to the soil. The solids control system uses water-based mud drilling system. The drilling waste generated by the water-based mud drilling system also contains effective mud. Disposal will also cause waste of mud, which needs to be recycled without mud disposal.

Mud zero discharge is the key to drilling waste treatment. It is the result of improved drilling technology, replacing traditional mud pools, reducing drilling environmental pollution and improving the necessary methods for environmental protection. The current Mud zero discharge includes water-based Mud zero discharge and oil-based Mud zero discharge. The two methods of Mud zero discharge are determined according to the mud treatment system adopted in the drilling.

Mud (drilling fluid), which is used to lubricate the drill bit, cement the well wall and cool down during the drilling process. In the whole drilling process, mud is of great significance to reduce drilling accidents and improve drilling efficiency. Generally, water-based mud systems and oil-based mud systems are mainly used in drilling sites.

However, the Mud zero discharge through the secondary filtration separation and recovery of drilling waste, which directly saves a lot of drilling mud, especially oil-based mud. Therefore, Mud zero discharge is the key to drilling solids control and drilling waste disposal.

Construction Waste treatment and reuse

Under the new pattern of circular economy, how to dispose of construction waste(Construction Waste treatment) with an annual increase of billions of tons has become one of the problems that the industry urgently needs to solve. In recent years, with the acceleration of urban construction and renovation, the problems of construction waste pollution and garbage siege have become increasingly prominent. In terms of inventory, the current increase in domestic construction waste reaches about 3.5 billion tons per year.

According to the source of construction waste, it is mainly divided into land excavation waste, road excavation waste, old building demolition waste, construction waste and building material waste. The demolition phase of buildings and the construction phase of new buildings are the key points for the control of construction waste. The demolition of old buildings and new construction accounted for 58% and 36%.

At present, our country’s treatment of construction waste is still in the relatively extensive landfill and stacking stage. In fact, construction waste is a renewable resource. After scientific recycling, separation, screening, and smelting, it can completely turn waste into treasure to restore its original performance, and reuse it as a renewable raw material. However, transforming construction waste into qualified, high-quality aggregates that can replace natural sand and gravel, and then into market-recognized products, is the biggest challenge facing companies.

KOSUN Mud Zero Discharge System Processing Flow

The Mud Zero Discharge System developed by KOSUN mainly includes shale shaker, centrifuges, cuttings dryers, and screw conveyors. After processing, it can reach an oil content about 2-5%, which is in line with national and industry standards.

After dewatering centrifuge separation and multifunctional purification unit, the harmful part of the mud is discharged with the solid phase. The liquid phase can be used to prepare the mud, discharge as wastewater or irrigate, and the solid part is solidified and then landfilled.

On-site centralized processing while drilling, using physical centrifugal separation technology to recover most of the base oil on-site, reducing the oil content and total amount of waste (the solid phase oil content of the spin dryer is 2%-12%, and the solid phase oil content of the centrifuge is about 13%, the treated solid phase is transported to the centralized treatment station for further treatment, and the liquid phase is returned to the circulation system for use. The advantage of on-site centrifugal deoiling while drilling is that it reduces the total amount of waste at the source, recovers reusable oil-based mud, and the treated waste is easy to store and transport, which greatly reduces the time and energy consumption of subsequent processing.

Dewatering principle of decanter centrifuge

The decanter centrifuge uses the principle of centrifugal sedimentation to separate the drilling suspension. The suspension enters the drum from the feed pipe through the liquid outlet hole in the screw pusher, and the solid particles are pushed to the inner wall of the drum under the action of centrifugal force and pass through the screw. The blades on the pusher are pushed to the slag discharge port at the small end of the rotating drum, and the liquid phase overflows through the overflow hole at the big end of the rotating drum. Such continuous circulation, in order to achieve the purpose of continuous separation. Sedimentation centrifuges belong to the category of horizontal spiral centrifuges, and the full name is horizontal spiral sedimentation centrifuges. crown

Dewatering principle of the decanter centrifuge: The decanter centrifuge uses the density difference between the solid and liquid phases, and under the action of centrifugal force, accelerates the sedimentation speed of the solid phase particles to achieve solid-liquid separation. The specific separation process is that the sludge and the flocculant liquid are sent into the mixing chamber in the drum through the inlet pipe, where the mixing and flocculation are carried out (if the sludge pump is dosing before the pump or the pipe is behind the pump, the flocculation reaction has been advanced) Due to the high-speed rotation and frictional resistance of the rotor (screw and drum), the sludge is accelerated inside the rotor and forms a cylindrical liquid ring layer (liquid ring area). Under the action of centrifugal force, the solid particles with larger specific gravity settle to the A mud layer (solid ring layer) is formed on the inner wall of the drum, and then the relative speed difference between the spiral and the drum is used to push the solid phase to the cone end of the drum. After pushing out the liquid surface (shore area or drying area), the mud can be dehydrated and dried. It is discharged to the slag discharge port, and the supernatant is discharged from the big end of the drum to achieve solid-liquid separation.

Tailings processing is a major problem facing the mine producers.

Tailings refers to the waste slag discharged by mining enterprises after the completion of mineral processing, which is mostly discharged in the form of mud to form the tailings pond. The tailing pond covers a large area and has a great potential safety hazard. In addition, the water from the tailing rich in mineral dressing agents penetrates into the ground, causing great pollution to the environment and groundwater. Therefore, tailings processing is a major problem facing the mine producers.

Tailings are the “wastes” discharged by mining enterprises under certain technical and economic conditions, but most of them contain various colored, black, rare, rare earth and non-metallic minerals, which are valuable secondary resources. When technical and economic conditions permit, it can be effectively developed again. Tailings are profitable. How to deal with them?

Xi ‘an KOSUN dry tailings flotation rows using flotation, centrifugal dehydration dry process, tailings after a buffer tank with slurry pump to high speed frequency conversion in the horizontal screw centrifuge, all returned after high-speed centrifuge separation of the liquid grinding, classification work with again, while the solid phase by belt transporting chance to the tailings for dry lamination stack so as to ensure the long-term safety of the tailings.

Flotation dry discharge of tailings is a new technology of tailings disposal, which is not only technically advanced and feasible, but also maximizes the economic benefits of mining enterprises. KOSUN’s tailings flotation dry discharge process equipment is mainly composed of grading cyclone group, coarse size tailings dry discharge high-frequency screen, efficient deep cone thickener, high pressure filter press and other equipment. It is mainly used for the dehydration treatment of tailings in concentrator to achieve the purpose of dry pile of tailings, so as to recover available resources and reduce environmental pollution.

Analysis of Resource Utilization of Sludge

KOSUN is a professional company that provides solid-liquid separation products and integrated solutions to solid waste disposal in the fields of energy conservation and environment protection, and focuses on development and services of complete technologies and equipment in sludge reduction, harmlessness and resource utilization. The sludge treated by KOSUN vertical centrifuge can be used as various resources in the following fields:

1. Agricultural resource utilization of sludge
If the sludge is used for agricultural purposes, it has the advantages of low operating cost, low energy consumption and low investment, and the organic part in sludge can be converted into the modifier component in the soil, so this utilization way is taken as the most promising disposal method.

2. Building materials utilization of sludge

2.1. Cementitious materials utilization of sludge
For sludge, it often contains more ash, especially in the treatment of sludge in wastewater by coagulation method, which contains a lot of Fe and Al components, and can be used as additives of building materials.

2.2. Sludge ceramsite
For lightweight ceramsite, it is usually used as a flower covering material or as a concrete aggregate and roadbed.

2.3. Sludge brick
Relevant researches show that sewer sludge can be used to make ecological bricks used in construction. This kind of brick is actually made by the following process: 10% sludge is mixed into the clay and then fired at 900°C, which can optimize the effect.

3. Animal feed utilization of sludge

Sludge contains lots of corresponding substances with many useful values, such as ash content ratio of 26.1% to 46.3%, fatty acids of 0 to 3.5%, and crude protein of 28.4% to 40.8%. Therefore, it can be treated as feed protein.

4. Sludge as fuel

The sludge itself is rich in organic matter. After low-temperature carbonization of sludge, the calorific value is equivalent to lignite, so the sludge can be used as fuel with a low calorific value.

If the sludge is not treated and is directly discharged into the environment, it will be seriously harmful to the surrounding environment. After the sludge is treated harmlessly, stabilized and reduced in volume, it can be used as a valuable resource in many fields.

CNOOC’s oil and gas reserves have hit a new record high, and CNOOC people are amazing!

On March 21, the reporter learned from China National Offshore Oil Corporation (CNOOC) that the Company released its 2018 annual performance report. CNOOC steadily increased oil and gas reserve and production. The annual net oil and gas production reached 475 million barrels of oil equivalent, and continued to maintain cost competitive advantages. The main cost of barrel oil continued to decline year on year, creating a record of five consecutive years of cost reduction. By the end of 2018, the company’s net proven reserves reached 4.96 billion barrels of oil equivalent, hitting a new record high, and the resource base for sustainable development in the future will be more solid.

In the next step, CNOOC has formulated a strategy for deepwater development in the South China Sea. It plans to build a deepwater oilfield cluster in the eastern part of the South China Sea in the next few years, and build the first 100 billion cubic meters deepwater gas field discovered by China in the western South China Sea, and continue to increase investment in exploration and development, deepen the potential of oil and gas resources in the South China Sea, and enhance the comprehensive support capability of oil and gas.

IEA: An acute shortage of global fuel oil supply will continue in next two years

The International Energy Agency (IEA) estimates that fuel oil supply is expected to face an acute shortage before 2020 when sulfur limit for marine fuel is set due to upgrade in refinery and a decline in medium and heavy crude oil production. According to the new regulations of the International Maritime Organization (IMO), by January 2020, the highest proportion of marine fuel sulfur will be reduced from the current 3.5% to 0.5%.

The IEA says, since November last year, due to the OPEC and non-OPEC (such as Russia) production reductions, the global production of medium and heavy crude oil has dropped by 1.4 million barrels per day, reducing the residual fuel oil market by 500,000 barrels per day. In the fourth quarter of last year, global demand for residual fuel oil was 6.74 million barrels per day, declining by 2.2% year-on-year.

The IEA states that the reduction in global crude oil supply is narrowing the profit margin of complex refineries comparing with simpler ones, which in turn leads to the disappearance of advantages of complex refineries. The increasing strengthening of fuel oil cracking in the past five months has made upgrades less feasible.
