SOLVENT RECOVERY PROCESS UNITS

Recovered Solvent Polishing & Quality Release

Removes trace color, particles, acidity or non-volatile contamination after main recovery.

Solvent Final Polishing & Release

METHOD & PROCESS PRINCIPLE

Adsorption, neutralization, fine filtration or guard-bed treatment is selected after laboratory validation.

MAIN EQUIPMENT & PACKAGE LIMITS

Polishing vessel, activated carbon/media, filters, dosing, pumps, analyzers and product receiver.

CRITICAL DESIGN INPUTS

Spent-solvent composition, water and solids, azeotrope/VLE behavior, corrosion/compatibility, batch variability, recovery purity, residue route and hazardous-area data. Final acidity, color, non-volatile residue, particle and purity limits.

ENGINEERING DELIVERABLES
