Industrial used oil recycling and treatment solution

Industry News / Chat on line / Give me a price / July 11, 2025

Industrial used oil—generated from machinery lubrication, manufacturing processes, and power generation—contains heavy metals, sludge, and chemical contaminants. If mishandled, it pollutes soil and water, violates environmental regulations, and wastes a valuable resource. Industrial used oil recycling through distillation is a common and effective method for recovering usable products from contaminated or degraded oils.

One of the most advanced solutions in this field is the DOING waste oil recycling distillation machine designed for industrial applications of all sizes, providing equipment from 100kg per day to 14 tons per day per set. This article explores industrial used oil recycling solutions, focusing on the innovative waste oil recycling distillation machine developed by DOING.

一.Process of DOING waste oil recycling distillation machine

1. Pre-Treatment: 

(This prevents damage to distillation equipment and ensures purity.)

Filtration: The used oil is first filtered to remove any large solid particles and debris.

Dehydration: Water and other volatile contaminants are removed using methods such as heating or vacuum dehydration.(if water content is high over 30%)

2.Distillation:

Heat transfer oil preparation: Start the heat transfer oil furnace and pump the heat transfer oil into the distillation reactor, catalytic tower and decolorization system for subsequent use.

High temperature heating: Use an oil pump to transport the waste oil to the distillation reactor, and quickly heat the reactor through a dual heating system. When the distillation reactor reaches a certain temperature, it evaporates and a large amount of oil and gas will evaporate. Distillation:

DOING has designed two types of catalysts. One is the traditional acid-base washing process, which first condenses the oil gas into oil and adds acid-base catalyst for purification. The other is a new solid catalyst. The oil gas produced by distillation will enter the catalytic tower, and then condense into oil after purification by catalysts A and B.

The choice of these two types of catalysts. We will make recommendations based on your materials and processing capabilities.

3.Post-Treatment:

Further purification: The oil after distillation may have a darker color and unpleasant odor. Generally, the oil will be purified for a second time: using white clay decolorization and DOING patented deodorization device to purify the gas

二.The application of refined products

1. Fuel Oil: It can be used for heavy machinery, such as tractors, ships, trucks, boiler, diesel generators.

2. Asphalt and Bitumen: It can be used in road construction and other applications requiring bituminous materials.

三. The advantages of DOING waste oil recycling distillation machine

1.High recovery efficiency: Converts 80-85% of used oil into usable products (e.g., 10 tons of waste oil yields 8-8.5 tons of fuel oil), outperforming conventional systems (60-70% yield).

2.Good quality: It is made of national standard materials Q245R and Q345R, and can also be customized with stainless steel to prevent corrosion and improve the service life and stability of the waste oil distillation machine.

3.Safety: It is equipped with a comprehensive safety system, including over-temperature protection and pressure relief valve to ensure the safety of operators and DOING waste oil distillation machine.

4.Advanced automation: PLC intelligent control system monitors temperature, pressure, and flow in real time, reducing human error and ensuring stable output.

5.Environmental compliance: Equipped with multi-stage exhaust gas treatment device, meets strict emission standards and reduces the pollution of industrial waste oil emissions to soil and water.

6.Cost savings: The exhaust gas generated by the reactor can be used as heating fuel

7.Flexible capacity: Available in 0.1-14 tons/day models, suitable for small workshops (e.g., auto repair shops) to large refineries.
