A crude oily sludge treatment plant from Kingtiger Co., Ltd. is a basic item in the petroleum industry, and you will find that in the first few phases of the process of producing fuel products, there are provisions for the removal of sludge.
There are basically two types of crude sewage sludge pyrolysis plant: portable and fixed. Between them, there are different kinds of removal systems used. The kind of plant used in a mining operation depends on the location of the source and the type of raw material to be processed. However, whether or not it is portable or fixed, and no matter what type of separation system is used, the process works the same way.
First, solids are removed mechanically it is required. The crude oil is then heated to reduce viscosity and enhance mobility. Then, the crude oil is dosed with a de-emulsifier to break down emulsions, after which a polymer is used to enhance the removal of solids and dry cakes.
There are two well-known waste oil layouts. The first one uses one high-performance three-phase decanter centrifuge. This usually produces oil that is good enough to be returned to an oil refinery for further processing. The second one removes solids in two decanter centrifuges that uses a downstream separation of oil, water, and solids. Each decanter has a three-phase disk stack separator.
The resulting product of the second type of centrifuge is of a much a higher quality than the second type of centrifuge. However, it requires more capital.
If you search for it online, you will see that there are many companies out there that are in the business of manufacturing sludge treatment plants and helping clients set them up. You might think that they are only used in crude oil mining out at sea. However, there are many cases when they are used. One very good example is the processing of slop oil, which is crude oil collected from open lagoons. Slop oil has a higher solid content and viscosity and thus require thorough processing.

Another case where a sludge oil treatment plant is used is when three-sludge needs to be processed. Three sludge refers to the waste generated at the oil refineries and composed of biological sludge, flotation scum, and oil sludge. A decanter centrifuge is used to recover more oil from the waste.
Another case where a sludge treatment plant is that of storage tanks. Often, when storage tanks are drained of their content, sludge remains at the bottom. A treatment centrifuge is necessary to remove the oil content.
As we said before, although the basics of how a sludge treatment plant works is the same no matter what system is used, there are differences in the details. There is a big difference between a single centrifuge and a double centrifuge system.
