Waste Oils / Oil Recovery Applications
release:dewater123   browse:892times

Lifeng MDS and TRP sludge dewatering machines provide world-class standards for high-performance specially equipped to meet the separation requirements of the waste oil processing industry with specialized separation equipment and systems technology. Whether it is 2-phase or 3-phase separation, the Lifeng range of MDS and TRP offer high performance separation solutions with a very small footprint. The Lifeng range of MDS and TRP series were designed and developed for maximum oil recovery, solids capture and cake dryness at high throughputs with significantly reduced power consumption.

Generally waste oil treatment plant and system layouts: Waste oil systems vary depending on the unique source and make-up of the raw product and the customer's requirements regarding quality of the products after processing. However, a typical processing plant layout for most oily wastes from the petroleum industry will generally comprise the following:

·                         Mechanical removal of solids, if required

·                         Heating to reduce viscosity and thus enhance mobility of the phase

·                         De-emulsifier dosing to break emulsions and make oil, water and solids bound in the emulsion accessible for centrifugal separation

·                         Polymer dosing to enhance solids removal rates and cake dryness

Two well-known and proven waste oils layouts are:

Waste oil, water, and solids separation in one high performance 3-phase MDS and TRP. Oil quality produced in such a system is usually good enough for return to the crude oil side of the refinery.

Typical 3-phase decanter performance:

Oil phase:

1-3% water

Below 1,000 ppm solids

Water phase:

1-3% oil

1,000-3,000 mg/L solids

Solids phase:

20-50% dry solids
