METHOD & PROCESS PRINCIPLE
Vacuum distillation controls product temperature while handling non-condensables and leakage load.
SOLVENT RECOVERY PROCESS UNITS
Vacuum Solvent Recovery
Reduces boiling temperature for heat-sensitive or high-boiling solvent mixtures.
MAIN EQUIPMENT & PACKAGE LIMITS
Vacuum column/evaporator, ejector or liquid-ring package, condensers, receivers and seal system.
CRITICAL DESIGN INPUTS
Spent-solvent composition, water and solids, azeotrope/VLE behavior, corrosion/compatibility, batch variability, recovery purity, residue route and hazardous-area data. Required vacuum level, allowable temperature and non-condensable load.
ENGINEERING DELIVERABLES
