Lubricating ( motor oil, engine oil, hydraulic, gear box oil, turbine oil etc.) oil is widely used in the fields of manufacturing, transportation, chemical industry ect. With the development of national economy, the demanded quantity is increasing. Lubrication oil is used for lubricating, cooling, anti-rust, sealing, buffering purpose in all sorts of machineries. Because contaminated by dust, metal from environment, and working in high speed parts, contacting with air and polymerization, condensation, oxidation ect reactions occurred. The lubricating oil is gradually deteriorating during using, the main appearance is the color become darker, acidity number increasing, odor discharging, and oil sludge, precipitate produced. In fact, lubricating oil is deteriorated 1-10% of its hydrocarbons, most of the rest hydrocarbons are still the viscosity performer and effective components, this is the potential motivation of waste lubricating oil regeneration.
Used lubricating oil contains oxygen-carrying, nitrogen-carrying, sulfurate-carrying organic compound, and chemical additives, dumping or burning these lubricants would generate a lot of pollution and waste energy resource. With the increasingly dried-up of petroleum resource and strengthening of environmental consciousness
as well rising of oil price, regeneration of used oil is attached importance by the countries worldwide. Regeneration of used oil could safe energy resource, change waste in to valuables, reduce its pollution to environment, has great economic and social benefits.
Recent years, the advanced countries in the world deeply researched the used lube oil recycling process, placeing emphasis on environment protection, making used oil not pollute environment, no secondary pollution during regeneration, saving energy consumption, pollution free, upsizing, high recovery rate is the trend.
There are different processes in the world developed for reclaiming of used lubricants. Each of them more or less has its advantages or disadvantages, the best way is optimize the design by combining some process of them and avoid the shortages of them to make the equipment has the best performance, also ensure the best quality of oil.
With years efforts, our engineers in
We could provide equipment and solutions for:
1. Column type atmospheric distillation and vacuum distillation +furfural rectification
This process is suitable for large scale recycling project, the oil quality level is highest except hydrotreating.
2. Vessel type vacuum distillation process
This process is very flexible, the oil quality is good, no need high length columns, operation is easy and automatic. This process can be medium size or large size.
3. Thin film process and short path molecular evaporation
This process is more vulnerable to the contaminants of used oil. Also could not sustain the coking problems. So the pretreatment of oil is very important. The investment for short path process is higher than vessel type. Also the molecular evaporated oil has darker color, so the after treatment takes more works. The advantage is the oil from short path treatment maintains more than 70% additives of oil, so the oil indexes are higher.
Except oil distillation process for production of base oil, we also able to provide equipment for production of diesel from used lube oil. It is cracking process with catalyzing treatment, the design of cracking process is very important, it determines the quality of oil, with the best design of equipment, we can receive good quality diesel can be used in common compression diesel engine.
