Solvent Extraction

We have developed two kinds of oil extraction process(rotor extraction and loop extraction). Till now, more than 10 oil extraction plants with working capacity over 1000MT have been built. Our oil extraction design, installation, and equipment are popular for less water, power, steam and solvent consumption; less oil residue in meal, top quality finished meal and crude oil.

Loop Extraction Process

1. Rotation speed of Loop Extractor can be adjusted according to quantity of the incoming oil-bearing materials. In addition, constant material level in the above Buffer Tank avoids solvent leakage. It is negative pressure in the extractor, whcih reduces solvent leakage.
2. Advanced miscella circulation will reduce fresh solvent use, reduce oil residue in meal, increase miscella concentration, and saves energy by reducing quantity of miscella entering into the evaporation system.
3. Thin material layer in extractor ease percolation filtration. There is turnover at the bending part of Loop Extractor, which will reduce extraction corner. But this will cause too much meal in miscella. The meal should be removed before entering into the evaporation system.

Rotor Extraction

1. Rotation speed of Rotor Extractor and Air Lock can be adjusted according to quantity of the incoming material. Keep constant material level in the above Buffer Tank make it easy to form negative pressure in the extractor and constant material level reduces solvent leakage.
2. Advanced miscella circulation reduces fresh solvent use, reduce oil residue in meal, increase miscella concentration, and saves energy by reducing quantity of miscella entering into the evaporation system.
3. High material level eases it to form immersion extraction and reduce the meal quantity in miscella. This will improve quality of crude oil and prevent against scaling in the evaporation system.
4. Especially suitable for extraction of pressed cake
