Yes, industrial waste oil filtration and regeneration is a real and feasible technology. Through professional filtration and regeneration equipment, impurities, moisture, pollutants, etc. in waste oil can be removed and its performance can be restored, thereby realizing the recycling of resources. The following is a detailed description of industrial waste oil filtration and regeneration:
Waste oil regeneration mainly removes pollutants in oil and restores its performance through physical, chemical or physicochemical methods. Common methods include:
- Physical methods: filtration, centrifugal separation, vacuum dehydration, etc.
- Chemical methods: acid washing, alkali washing, adsorption, etc.
- Physical and chemical methods: combining physical and chemical methods, such as hydrofining, solvent extraction, etc.
2.1 Pretreatment
- Sedimentation: Let the waste oil stand to allow large particles of impurities to precipitate.
- Coarse filtration: Remove large particles of impurities through a filter or filter cloth.
2.2 Depth filtration
- Precision filtration: Use an oil filter to remove tiny particles.
- Centrifugal separation: Use centrifugal force to separate solid impurities and water in oil.
2.3 Dehydration and degassing
- Vacuum dehydration: Remove water and gas in oil under vacuum.
- Heating evaporation: Evaporate part of the water by heating.
2.4 Chemical treatment
- Acid washing/alkaline washing: Remove acidic or alkaline substances in oil.
- Adsorption treatment: Use adsorbents such as activated clay and silica gel to remove colloids and pigments.
2.5 Refining
- Hydrorefining: Improve oil performance through hydrogenation reaction.
- Solvent extraction: Use solvents to separate harmful substances in oil.
3.1 Filtration equipment
- Plate and frame oil filter: Used to remove solid impurities.
- Vacuum oil filter: Used for dehydration and degassing.
- Centrifugal oil filter: Used to separate impurities and water.
3.2 Chemical treatment equipment
- Acid washing/alkaline washing equipment: used to remove acidic or alkaline substances.
- Adsorption tower: used to adsorb colloids and pigments.
3.3 Refining equipment
- Hydrogenation reactor: used for hydrogenation refining.
- Solvent extraction equipment: used for solvent extraction.
- Lubricating oil regeneration: regenerate waste lubricating oil into reusable lubricating oil.
- Transformer oil regeneration: restore the insulation properties of transformer oil.
- Hydraulic oil regeneration: remove pollutants in hydraulic oil and restore its performance.
- Fuel oil regeneration: regenerate waste fuel oil into usable fuel.
1. Environmental protection: reduce the pollution of waste oil to the environment.
2. Economic: reduce the cost of purchasing new oil.
3. Resource conservation: realize the recycling of resources.
4. Energy conservation and emission reduction: reduce the consumption of petroleum resources and carbon emissions.
1. Classification of waste oil:
- Different types of waste oil require different regeneration processes.
2. Equipment selection:
- ｓｅｌｅｃｔ appropriate equipment according to the nature and processing volume of the waste oil.
3. Environmental compliance:
- Ensure that the regeneration process complies with environmental regulations to avoid secondary pollution.
4. Technical expertise:
- Waste oil regeneration requires professional technology and equipment, and it is recommended to be operated by a professional company.
- Domestic: Waste oil regeneration technology is relatively mature, and many companies provide waste oil recycling and regeneration services.
- International: European and American countries are technologically advanced in the field of waste oil regeneration, and environmental protection requirements are more stringent.
Industrial waste oil filtration regeneration is a real and effective technology that can convert waste oil into reusable resources with significant environmental and economic value. If you have waste oil treatment needs, it is recommended to contact a professional waste oil regeneration company or equipment supplier.
