METHOD & PROCESS PRINCIPLE
Deep vacuum lowers boiling temperature; wash and entrainment control protect overhead and side products.
WASTE-OIL PROCESS UNITS
Waste Oil Vacuum Distillation
Separates recoverable lubricant-range fractions at reduced temperature to limit degradation.
MAIN EQUIPMENT & PACKAGE LIMITS
Vacuum column, heater or reboiler, ejector/liquid-ring system, condensers, receivers, pumps and side strippers.
CRITICAL DESIGN INPUTS
Representative waste-oil assay including water, light fuels, viscosity, density, ash, metals, halogens, glycol, PCB screening, CCR/MCR and distillation curve. Required product cut ranges, allowable film temperature and vacuum-system non-condensable load.
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
Waste-oil re-refining and lube-range fraction recovery.
CODES, STANDARDS & QUALITY BASIS
ASME VIII, TEMA/API 660, API 520/521; EN 13445/DIN or GOST vessel requirements if selected.
CONTRACTUAL CODE BASIS
ASME VIII, TEMA/API 660, API 520/521; EN 13445/DIN or GOST vessel requirements if selected.
