PPGT-TB Waste Oil to Base Oil WFE Vacuum Distillation Plant

PPGT-TB Waste Oil To Base Oil Plant series is a process technology based on vacuum distillation (using TFE Wiped Film Evaporator) to re-refining of waste/used lubricating oils to near virgin API Group I base oils ranging from SN70 to SN500. Re-refining is the term used to describe use of PPGT-TB technology to extract the lubricating base oil from waste lubricants. Water, fuel oil, additives and sludge are separated from the base oil. The base oil yield can reach up to 75%-80%, ensuring high efficiency in the recovery process. PPGT’s complete six-step process treats used oil to produce virgin base oil, which meets API Group I specifications:

  1. Pre-treatment
  2. Water and Light Fuel Removal
  3. Raw Gas Oil (Diesel) Removal
  4. Separation of Lube Distillate by Wiped Film Evaporation (WFE)
  5. Fractionation to split the base oil into desired viscosity cuts
  6. Refining of the base oils to remove bad color, odour

PPGT-TB series best feedstock is waste engine oil, used motor oil (Crankcase). It should have less than 10% water content. Other industrial oils, Transmission Fluid, Gear Oil, Hydraulic Fluid can be included.

PPGT-DF Waste Oil to Diesel Continuous Fractional Distillation Plant

The PPGT-DF Waste Oil Distillation To Diesel Plant is designed to thermally break down the long chain hydrocarbons in waste motor oil, converting them into valuable diesel fuel. It also produces byproducts such as light gas oil, light hydrocarbons, water, and asphaltene sludge. The high flash point, high cetane number diesel yield can reach up to 80%-85%, ensuring high efficiency in the conversion process. With PurePath’s exclusive fractionating and ultrasonic desulfurizing technologies, the diesel produced by our distillation plant meets the Euro 5 related standards. The five steps for distilling diesel from waste motor oil are:

  1. Pre-treatment
  2. Dehydration and Light Ends Removal
  3. Catalytic Cracking
  4. Fractionation and Condensation
  5. Refining and Desulfurization

The PPGT-DF Waste Oil Distillation Plant is capable of converting various types of waste oil feedstock into diesel fuel and other valuable byproducts. These include waste motor oil, used engine oil, waste gear oil, waste crankcase oil, waste hydraulic oil, tire/plastic pyrolysis oil, slop oil, and more.

5 Key Operational Metrics to Boost Profits in Used Oil Recycling Plants

If you’re in the used oil recycling business, then you already know that the “spread” between the cost of the waste oil and the price received for the base oil is only half the battle. The real profit is made or lost in the tiny details of the operation. High operating costs, frequent catalyst changes, or a 5% decrease in yield can destroy any profit margin in a hurry, much faster than any changes in the market can affect it.
