Waste Oil Recycling Plant
Waste oil is fuel or furnace oil contaminated with water and slop oil is fuel oil / other hydrocarbon oil contaminated with water in large shipping vessels or large storage tanks. Typically, this water cannot be separated using a centrifugal separator as it is highly emulsified. It can only be separated using molecular distillation, a process known as the dehydration of waste oil.
Recycling the waste oil is done by following procedure:
- Pretreatment: screening process is conducted to remove particles and free water is separated from waste Oil.
- Dehydration: moisture content is removed by using evaporator under high vacuum and controlled temperature.

Available Technologies for Dehydration
ATFD (Agitated Thin Film Dryer)
- ATFD works by spreading the material as a thin film on a heated surface while being agitated by a rotor with blades, which enhances heat transfer and ensures uniform drying. ATFDs are compact and energy-efficient.
- Fully Automated (SCADA + PLC) & Continuous Process.
Available Capacities: 50 TPD, 100 TPD, 200 TPD.
Column Evaporator
- Column-type evaporators are more preferable when the production capacity is less than 50 TPD due to their low initial cost.
- Multiple cuts can be separated by one evaporator.
- Batchwise process & Semi Continuous Process using PLC.
Available Capacities: 10 TPD, 20 TPD, 50 TPD.
