Dredging Slurry Separation Solution

River dredging process system is generally adopts a cutter suction dredger to absorb the muddy water mixture at the bottom of river, and then transport it along the pipeline to a sludge drying treatment field. After machine sorts the garbage mixed in mud, the mud is passed into the concentration tank in the field, and the mud water separation is carried out through the mud treatment system. Finally, water reaches the standard discharge, and the wet sludge is sent to sludge dewatering equipment to dehydrate and becomes solidified mud cake for reusing.

Dredging Slurry Separation Solution mainly used for the separation of sludge from rivers. KOSUN Dredging Slurry Separation Solution is consist of shale shaker, desander, desilter or decanter centrifuge for 3 to 6 stage separation depending on the needs.

KOSUN Dredging Slurry Separation Solution is consisting of 3 parts. The first one is the dredging boat and first stage separation pool for large size of the trash. The dredging boat is always moving on the surface of the lake or river, and the suction unit would go down deep to the bottom of the lake or river and then suck sludge then transfer to the ground by a hose which is always float on the water surface. On the ground, there will be a pool which is divided into several parts by different mesh size of wire screen. The sludge flow coming out from the hose will get into the pool; the large size of the trash in the sludge would be blocked by these several wire screens, while the slurry will flow away for next process.

The second part of the Dredging Slurry Separation Solution is the recycling system which is including several equipment that is used especially for the solids and liquid separation. The slurry will be fed into a scalping shaker, here the solids which is large than 1/8 inch would be separated out, and the slurry would then be pump transferred to the desander for much fine solids removing. After treated by the desander, almost all the solids with size of 50 microns would be removed out.

The third part of the Dredging Slurry Separation Solution is the ultra-fine solids removing equipment. Some contractors like to use the filter press as the final solids removing units, the solids separated are really dry and shaped like cake. While another option is to use the decanter centrifuge that could be used to remove the ultra-fine solids with size down to 2 microns. After treated by the filter press or the centrifuge, the water is already clean that could be flow back to the lake or river.

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.

The No. 6 Gas Production Plant, Changqing Oilfield Company makes a drilling footage over 100,000m

On April 1, the drilling footage of the New Year’s production capacity of the No. 6 Gas Production Plant, Changqing Oilfield Company exceeded 100,000 meters, and the time to reach this length was 28 days earlier than the year of 2018.

In order to ensure the quality and efficiency of production and construction, as well as high-quality and rapid development, the No. 6 Gas Production Plant has continuously deepened geological research and promoted technological innovation. On March 6, the first analysis while drilling and deployment disclosure meeting this year preliminarily defined the overall plan for the annual production and construction deployment, and carried out the geological analysis while drilling according to the implementation effect, and timely optimized and adjusted the deployment. Up to now, a total of 27 additional coordinates have been deployed, 11 production and construction favorable zones have been implemented, and 339 effective coordinates have been prepared.

At the same time, relying on the special projects and key technologies of Changqing Oilfield Company, the “twice-drilling” technology and the “small borehole” test were actively promoted. On March 8, the gas well with twice-drilling technology in the Gaoqiao area was successfully drilled. The second section to the finished drilling only took 11.21 days, which was 30% higher than the drilling speed of a conventional well with the same depth.

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.
