PESCO-BEAM Oil Recovery Systems use atmospheric distillation to remove light ends, water, and gas-oil. After which high vacuum Short Path and Thin Film Evaporators, operating at moderately high temperatures, recover the lube oil fraction. Moderate temperatures and low pressure protects the lube fractions from “cracking”. Asphaltene and other solids exiting the system can be used for roads or low grade bunker 6. Short Path and Thin Film Evaporators are useful for processing thermally sensitive products, allowing for reduced process time at lower evaporation temperatures, under vacuum conditions.
PESCO-BEAM can also design and build high efficiency mechanical and thermal vapor re-compression evaporation units to suit your needs.Each modular unit is:
Short Path and Thin Film Evaporators are similar, in that they operate at moderate temperatures and low residence time to prevent thermal decomposition.
The primary difference is that the Short Path Evaporator's condenser is inside the evaporator body so there is very little distance between the heating surface and the condensing surface, which means minimal pressure drops at high evaporation rates, gentle evaporation under low vacuum pressures for heat sensitive products, and recovery of entrained droplets.
Short Path Evaporators can be used down to 0.001 mbar, compared to the external condenser and slightly longer residence time of Thin Film Evaporators, which can be used down to roughly 1 mbar.
