METHOD & PROCESS PRINCIPLE
Closed receipt, sampling, classification and segregated storage are used before batch formulation or continuous feeding.
SOLVENT RECOVERY PROCESS UNITS
Spent-Solvent Collection & Segregation
Maintains traceability and prevents incompatible mixtures before recovery.
MAIN EQUIPMENT & PACKAGE LIMITS
Unloading connections, quarantine tanks, sampling, transfer pumps, grounding, vents and bunded drainage.
CRITICAL DESIGN INPUTS
Spent-solvent composition, water and solids, azeotrope/VLE behavior, corrosion/compatibility, batch variability, recovery purity, residue route and hazardous-area data.
ENGINEERING DELIVERABLES
Design Basis, material balance, PFD, P&ID, equipment and instrument datasheets, line/equipment lists, control narrative, cause-and-effect, layout/3D interfaces, inspection plan, operating and commissioning procedures.
AUTOMATION, SAFETY & HSE
Closed handling, relief/vent/drain routing, alarms and trips, hazardous-area classification, HAZOP actions, maintainable isolation, fire protection and emergency shutdown interfaces.
APPLICATIONS & PERFORMANCE BASIS
Paint, coating, pharmaceutical, extraction and chemical-process spent solvents.
