Solvent Extraction Condenser Shell Tube Heat Exchanger for Oil Extraction Line

The Solvent Extraction Condenser is the vacuum side workhorse of any solvent extraction line. A large volume of solvent vapour leaves the evaporators, the desolventizer toaster and the extractor, and unless it is condensed quickly and completely the vacuum system suffers, solvent losses rise and the whole plant becomes inefficient.

Our condenser is a horizontal shell and tube heat exchanger in which cooling water circulates through the tubes while solvent vapour flows across them inside the shell. The generous heat exchange area, turbulence promoting baffles and multi pass water path guarantee a high heat transfer coefficient, so solvent vapour condenses on the tube surface and drains smoothly into the collection tank without flooding the shell.

Every unit is pressure tested, sand blasted and either two coat painted or fully stainless steel built according to the application, so it resists the mildly corrosive environment found in edible oil plants. The condenser works with the mineral oil absorption column and the vacuum pump to form a complete, closed solvent recovery loop.

• High Heat Transfer: Corrugated tubes and segmental baffles increase turbulence so that the condenser achieves a high heat transfer coefficient with a compact footprint.
• Low Pressure Drop: The vapour path is designed to minimise resistance, which preserves the deep vacuum needed for low temperature evaporation of solvent.
• Corrosion Resistant: Stainless steel tubes and optional stainless shells withstand the aggressive vapour and water vapour mixture found in extraction service.
• Complete Drainage: The shell is mounted with a slight slope and a generous condensate outlet so that liquid solvent leaves quickly and never blocks heat transfer.
• Leak Proof Build: All joints are welded, all connections are flanged and each unit is hydro tested before shipment to guarantee vacuum tightness on site.
• Modular Sizing: Heat exchange area from 20 to 300 square metres allows the condenser to match small batch plants as well as large continuous extraction lines.

The Solvent Extraction Condenser is applied in edible oil solvent extraction plants, oil mills, solvent recovery units, desolventizer toaster vapour condensing and vacuum evaporation systems. It condenses solvent vapour coming from the evaporators, the DTDC and the flakes dryer, and it also serves in chemical and pharmaceutical plants where a reliable shell and tube condenser is required. It can be combined with a mineral oil absorption column for final solvent stripping.

The condenser is shipped fully assembled with tube bundles protected by end covers and all flanged faces capped to keep out dust and moisture. Units are braced inside mild steel frames for container and sea transport. We supply assembly drawings, hydro test reports and commissioning support, and the exchanger carries a twelve month warranty against manufacturing defects.
