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.

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.

Several Oily Sludge Management technologies

At present, the total amount of oily sludge produced in our country has exceeded 500 million tons every year, and the output also shows an increasing trend year by year. Oily sludge mainly from the following three aspects.( Oily Sludge Management)

Oily Sludge Management
Oily Sludge Management

(1) crude oil extraction process. Crude oil production process will produce a amount of oily sludge. The sludge produced mainly from the oil recovery wastewater treatment, the sedimentation caused by the added water purifying agent and the crude oil produced by drilling.

(2) Oil gathering process. Oil gathering process will produce a amount of oily sludge. Transfer stations and joint station tank sludge, sedimentation tank sediment, grease trap sediments are all oily sludge. Oil sands produced from natural gas purification plants and sludge are also oily sludge.

(3) Sewage treatment plant. Oil refinery wastewater treatment plant will also produce oily sludge, mainly from the biochemical pool of excess sludge, grease trap sediment, flotation tank scum, crude oil tank sediment.

Several Oily Sludge Management technologies

Oily sludge must be treated as it is detrimental to the environment. At present, there are several commonly used methods for the treatment of oily sludge in our country: incineration, thermal desorption, landfill, etc. In addition, there are biological treatment, coking and chemical heat washing.

In response to the requirement of resource-based, harmless and reduction of oily sludge treatment in our country, there are many new oily sludge treatment technologies emerging such as ultrasonic treatment of oily sludge technology, cement sludge co-treatment of oily sludge technology and Solvent extraction processing technology.

The source, composition, characteristics and nature of oily sludge in oilfields all over China are different, so the technology applied to oily sludge management is not the same. Therefore, the oil field in the selection of oily sludge treatment technology should be based on the advantages and disadvantages of various technologies and the scope of application. Combined with their own circumstances choose a reasonable technology.(Editor:Kosun Lily.Wang)

Prospects for Oil Sludge Management

With the promulgation of the new Environmental Law, the environmental requirements are getting higher and higher for oil fields, and free discharge of oil sludge will not be allowed any more. Oil Sludge Management is becoming a focal issue.

oil sludge management

oil sludge management

Oil sludge is oil mixed with soil. They will be mixed together and become very difficult to deal with. Oil sludge is mainly from two aspects: Firstly, crude oil from the stratum to the ground and accumulated in all kinds of containers, large tanks and recycling pools and other ground facilities; secondly, oil sludge produced by oil well operations.

Oily sludge is mainly derived from oil field mining and sewage treatment plants. In general, the sludge oil content is from 10% to 50%, and moisture content is from 40% to 90%. The ultimate purpose of oil sludge management is to reduce the harmful resources. The common oil sludge treatment methods are solvent extraction, incineration, biological, coking, oily sludge profile control, and comprehensive utilization of oil sludge. The results show that the current methods for oil sludge management have their own characteristics and scopes of application. As the oil sludge composition is so complex, there is no treatment method that can treat all types of oily sludge.

According to statistics, the pollutant treatment market size is about CNY100~150 billion each year, and according to a rough calculation, the investment in oil sludge management plant needs more than CNY150 billion.

Since 2007, Daqing Oilfield have built nine oil sludge management stations, and the annual treatment capacity can reach 3.2 million tons, all the oil sludge had been treated harmlessly. Changqing Oilfield built a Longdong oil field sludge treatment station in 2013 and used the physically and chemically combined methods, the oil content of the treated oil sludge is less than 2%, and moisture content is less than 60%, while the crude oil can be recovered. Xinjiang Fengcheng Oilfield Work Zone uses microbial agents to deal with heavy oil sludge and sludge oil content is reduced from 15% down to below 2% after treatment, which is very good. The current test has been reviewed by the company.

KOSUN can provide a corresponding set of oil sludge management plant, and our products have been exported to foreign countries, such as the United States, Europe, Russia, the Middle East and other regions, and our oil sludge treatment systems are well received by the foreign customers. If you need more information about our oil sludge management plant, please feel free to contact us! (Editor:Kosun Lily.Wang)
