PROCESS AND SYSTEM FOR EXTRACT VEGETABLE OIL FROM DISTILLERY FROM WHOLE DISTILLATE RESIDUE

Claims

A system and process for recovering oil from whole distillate residue, wherein the whole distillate residue is fed into a mechanical separation device, such as a screw press, stacked disc centrifuge, or three-phase centrifuge. The separation device separates the whole distillate residue into a first light fraction and a first heavy fraction. The first heavy fraction is transferred to a secondary whole distillate residue tank, and the first light fraction is transferred to a first decanter. The first decanter separates the first light fraction into a second light fraction and a second heavy fraction.The second heavy fraction is transferred to the whole distillate residue secondary tank with the first heavy fraction, and the second light fraction undergoes one or more additional separations before being combined with the oil-rich fine distillate residue stream and transferred downstream for oil recovery.
