1. What is Oil Dewaxing?
Oil dewaxing is a refining process that removes wax contaminants (e.g., paraffin and microcrystalline wax) from hydrocarbon feedstocks. This process is essential for improving the low-temperature properties and flow characteristics of products like lubricating oils and fuels.
2. Core Functions of Oil Dewaxing Equipment
Oil dewaxing equipment performs several critical functions:
· Feedstock Pre-Treatment: Removes impurities and moisture from crude oil or slack wax.
· Solvent Blending: Mixes solvents (e.g., MEK-toluene or propane) with the feedstock to reduce wax solubility.
· Chilling & Crystallization: Cools the solution to crystallize wax molecules.
· Filtration: Separates wax crystals from the oil-solvent blend using rotary drum filters or centrifuges.
· Solvent Recovery: Distills and recycles solvents for reuse.
3. Traditional vs. Modern Dewaxing Technologies
Aspect | Traditional Equipment | Modern Equipment |
Filtration | Manual or semi-automatic filters | Automated rotary drum filters |
Temperature Control | Manual cooling systems | Precision chilling units |
