Oil solvent evaporator is widely used in the solvent evaporation system of solvent extraction plant. It efficiently separates solvent from miscella.
The tubes in the oil solvent extractor are made of stainless steel, which ensures the material flows smoothly through the tubes conducive to heat exchange, and extends equipment’s service life. The oil solvent evaporator adopts the advanced micro-vacuum evaporation technology, which not only saves steam consumption but also improves the color and quality of the crude oil.
Features of Oil Solvent Evaporation
1. Evaporation within a vacuum for better oil quality.
2. Extraction system suitable for processing various raw materials.
Oil Solvent Evaporation System
1. Evaporation at negative pressure makes it possible to make full use of residual heat from secondary steam. Waste steam is supplemented to the steam ejector, which makes it unnecessary to supplement fresh steam to the 1-stage evaporator. Steam is saved by 30%.
2. Miscella from the 1-stage solvent evaporator is heated by high temperature oil from the stripper. And this highly increases the temperature of miscella which will be sent to the 2-stage solvent evaporator, and reduces energy consumption.
3. The miscella evaporates at low temperature, and the residual solvent is less in the light colored crude oil. It is not easy to scale in the solvent evaporators and oil stripper.
4. Stainless steel multi-tube condensers generate greater solvent recovery and save on space. All of these in turn lower the cost of production and the initial investment.
5. The vapor contactor has reduced the load of the DT condenser and increased the temperature of both fresh solvent and waste water discharged from the solvent –water separator.
6. The boiler tank minimizes solvent residual in waste water.
