EDIBLE OIL PROCESSING

Product-to-product heat recovery for refining and deodorization

Compact welded exchangers recover heat from hot refined oil to preheat incoming oil, reducing steam and cooling-water demand.

Deodorization heat recovery

Recover heat from oil leaving the high-temperature process

Deodorization commonly operates around 240–260°C under deep vacuum. Hot deodorized oil contains significant recoverable energy. A product-to-product exchanger transfers this heat to the incoming oil before final steam heating.

  • Lower steam demand
  • Lower cooling-water demand
  • Compact skid layout
  • Low product inventory
  • Welded construction without elastomer gaskets

Utility impact

Effective heat recovery can reduce fuel and steam consumption across the deodorization unit. Actual savings depend on plant capacity, temperature program and existing heat integration.

Close temperature approachMaximizes sensible-heat recovery between hot and cold oil streams.
Compact hold-upReduces valuable product inventory inside the exchanger.
High-temperature serviceWelded plate pack avoids gasket limitations.
Sanitary material options316L, 254 SMO and other project-specific materials.
Design factors

Viscosity changes strongly with temperature

Oil viscosity, pressure drop, residence time, allowable shear, fouling, cleaning method and product cross-contamination risk must be evaluated across the complete temperature profile.
