Waste Lubricating Oil to Diesel Plant

A waste lubricating oil to diesel plant processes suitable used hydraulic, gear, compressor, engine and other lubricating oils to recover a diesel-range fraction. The recovered liquid is not automatically road diesel: feed composition, distillation cut points, finishing steps, final fuel tests and local rules determine its correct classification and permitted use.

Feedstock Testing and Process Design

The process may include receiving and segregation, filtration, dehydration, light-end removal, controlled atmospheric or vacuum distillation, condensation, optional product finishing, process-gas treatment and residue handling. Water, coolant, solvents, sulfur, chlorine, solids, metals and degraded additives must be assessed because they affect corrosion control, equipment configuration and product quality.

Product Quality, Yield and Compliance

Representative feed samples should be tested for water, solids, density, viscosity, flash point, distillation range, sulfur, chlorine, ash, carbon residue and metals. Finished fuel must be checked against the agreed specification for its intended application. Capacity and yield should be based on testing, operating hours, utilities, a documented mass balance and acceptance criteria rather than a universal percentage.
