decanter centrifuge for waste oil separation

Refineries and oil residual management

Every oil refinery produces oil-bearing secondary contaminated material during its regular operations. Long-term accumulation of these materials might deplete storage areas and perhaps cause difficulties with normal vessel operation (if unattended).

As a result, refineries remove these oil-bearing contaminated materials from their storage tanks on a regular basis. Unless the materials may be utilized again in the refining process, they must be classified as hazardous waste, which can be costly. However, if processed, these contaminated materials may be reused and recycled and are no longer considered hazardous waste.

Environmental solution companies are those who assist refineries with the recycling processes and provide sustainable solutions for managing oil-bearing secondary material streams.

These companies often combine the use of decanter centrifuges with the use of thermal desorption units in order to maximize their material recovery from its residuals, resulting in a delisted non-hazardous solids cake.

Our Saudi clients have been using disc centrifuges to separate carbon from waste oil. However, due to the characteristics of waste oil, the disc centrifuge is prone to clogging. Once the disc centrifuge is clogged, it needs to be completely disassembled for cleaning.

Using a horizontal screw centrifuge will prevent material blockage. Therefore, our Saudi client specifically came from Saudi Arabia to our company for experiments, and the separation effect was very satisfactory to the client!
