Increasing the recovery of palm oil extract

Description Reagents and equipment Implemented projects Other solutions

Palm oil is the most widely consumed vegetable oil in the world. It can be found in everything from food to cosmetics.

The palm oil extraction process inevitably involves irreversible product losses, with processing waste (Palm Oil Mill Effluent, POME) being discharged in man-made settlement ponds. It may take decades for the oil to biodegrade in those ponds, which has negative impact on environment.

The oil losses during extraction at a factory with a capacity of 60 tons of fresh fruit bunches per hour range from 1% to 2.5%. Moreover, the discharged production waste (POME) - about 40 m3 per day - cannot be used for irrigation of plantations.

Indicator	Before implementation of the solution	After implementation of the solution
Oil losses at centrifuge treatment stage	0.9 – 1.2%	0.3 – 0.5%
Increase in oil extraction rate	Not applicable	up to 5%
Reduction in oil content in POME	Not applicable	by 2-3 times

Example of flowchart

One of the methods of Biomicrogels BMG-C4 application is using the agent after a centrifugal pulp that pulps unrefined palm oil into a clarifier.

Insertion of the agent at this stage makes possible to simplify the process of releasing oil particles from solid particles, which speeds up the process of separating the oil in the clarifier .. Introduction The agent increases the efficiency of separating the extracted oil, and also reduces the oil content in POME by 2-3 times.

How it works Preparation Transportation and storage Disposal Documents

Biomicrogel® Reagent for Oil Extraction BMG-C4 forming submicron films around oil droplets and on the surfaces of fruit solid particles and by this helping to release oil to float up to the surface.

Unlike other Biomicrogel® modifications used as a sorbent, flocculant, or flocculating agent, where the strength of films (microcapsules) is critical and must be maintained for a long period of time, in this case it is important to ensure just the short-term presence of such films on the surface of the solid particles, ensuring the oil is separated from the solids and the oil then floats to the surface of the water. After the process is completed, Biomicrogel® BMG-C4 remains in the water phase and in the solids.

Place an order

Biomicrogel® BMG-С4 is used in the form of a 3% solution.

In order to prepare the Biomicrogel BMG-C4 solution for use, it is necessary to use the special BMG PDS series preparation and dosing equipment while following the instruction manual for BMG-C4

Biomicrogel® BMG-С4 is supplied as powder.

It is packed in 25kg polypropylene bags; the bags are then placed on pallets. One pallet carries 20 bags, which is 500 kg of product.

To avoid hydrolysis or the growth of bacteria and fungi, resulting in a deterioration of the solution, use the Biomicrogel® BMG-С4 solution within 7 days of its preparation.

When the solution is prepared, it creates an environment for the growth of airborne or aquatic bacteria and fungi. Always add a biocide in storage areas where this process is taking place.

It is recommended to use isothiazoline-based biocides in the proportion of 700 ppm of agent per volume of water. Equipment for the preparation of the Biomicrogel® BMG-С4 treatment solution as well as any containers for its storage and any pipelines used should be pre-flushed and disinfected. Store the product in a cool and dry place. Keep the entire protective packaging safe until the product is used.

The guaranteed storage life is 24 months from date of production.

Biomicrogel® BMG-С4 shall be disposed of in accordance with effective legislation.
