METHOD & PROCESS PRINCIPLE
Steam, vacuum or thermal stripping is selected from solvent volatility, product sensitivity and water tolerance.
WASTE-OIL PROCESS UNITS
Solvent Recovery: Raffinate & Extract Stripping
Recovers dissolved solvent from both product and reject phases for closed-loop reuse.
MAIN EQUIPMENT & PACKAGE LIMITS
Raffinate stripper, extract stripper, reboilers, condensers, decanters, vacuum system, pumps and solvent receiver.
CRITICAL DESIGN INPUTS
Solvent properties, residual-solvent limit, temperature sensitivity, steam/water interaction and recovery target.
