BIOTECNOLOGIA DE ALIMENTOS


Degumming is the first operation in refining. The Impac® Degumming process consists of a mere hydration of the crude oil. Certain impurities like phospholipids, gums and proteins are soluble in oil in their anhydrous form, but insoluble once they are hydrated. This is how the hydratable phospholipids are removed from the oil. Part of the constituents however remain in the oil, and an acid treatment is needed to remove them.

Water degumming is more generally carried out in the extraction plant rather than in the refinery, lest foots should conglomerate in the crude oil intermediate tanks.

The aqueous phase obtained after degumming separation is recirculated into the meal stream of the toaster. Should lecithin be of significant commercial value, it can be dried separately.

DeSmet unique SPARBLEACH


The originality of Sparbleach® is that the adsorption of coloring matters by the bleaching earth is enhanced by means of sparge steam resulting in a significant saving in bleaching earth.

The Sparbleach® is a two stage vessel. Oil/earth mixure is introduced under vacuum into the top stage where it is heated and continuously agitated by injected sparge steam.

The dispersion of earth at optimum conditions of : vacuum temperature combined with steam agitation of the oil mass ensures ideal conditions to start the adsorption process.

The bottom holding compartment where the decoloration is completed is equipped with an arrangement of partitions ensuring uniform residence time and sparge steam distributors

Sparbleach® with prefiltration


De Smet has developped this new technology, which has now been adopted on a large scale by the industry.

This new process is based on the re-use of the spent bleaching earth, without removing it from the bleaching filters. Once the spent bleaching earth is re-used in the filter, it is discharged and evacuated.

The prefiltration requires an additional filter.

Main Advantages

- Substantial reduction of bleaching earth consumption

- Reduction of oil loss

- Reduction of utilities consumptions.

Solvent Recovery Unit


Highly demanding processors
The Qualistock® Deodoriser is a new fully integrated compact deodorising system, including a new steam injection concept, in which deaeration, heat exchanging, heating, deodorising/stripping, cooling and scrubbing all take place in one single vessel.

The Qualistock® (patented) has been developed for highly demanding processors seeking reliable, consistent and efficient product quality, and is the result of a continuous R&D effort based on the experience of more than 900 deodorising plants.
