Application of “Oilsep Ecology”  System for Oil Recovery in Palm Oil Mills

(Officer In-charge: Yahaya Hawari)

 

Description

Oilsep’ is a system designed and produced to accelerate the natural physical process of separation of two liquids and it is based on a purely physical principle. The machine exploits the different density and viscosity of the immiscible fluids and their different flow velocities as they pass through the elements inside the tank; this leads to their separation and re-aggregation on the basis of their density. This enables all liquids, whatever their density, to be recovered in a single step, even those with low density and viscosity (e.g. petroleum, gasoline, diesel and naphtha), which cannot be recovered using other systems. The system requires no centrifuges, coalescence devices, chemical additives, or scraper discs which require frequent regular maintenance and cause subsequent disposal problems.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

‘Oilsep’ is easy to install nearby the sludge pit and requires only electrical connection and water pipe connection. The effluent is pumped through a skimmer into the system by means of a peristaltic pump which uses a rotor connected to two rollers. As these rotate, the effluent is squeezed inside the rubber hose and pushed along inside the separation and re-combination tank. Here, the two liquids are separated and the oil is recovered.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Objectives

‘Oilsep Ecology’ system is a promising technology for palm oil millers to address the oil recovery as well as reduction in BOD load to the palm oil mill effluent (POME) treatment system.
