Used lube oil re-refining presentation »
STP RE-REFINING PROCESS MERITS
- Several Used Lube Oil Re-refining Plants implemented worldwide from 16,000 Ton/year to 120,000 Ton/year capacity
- Advanced vacuum system for high vacuum level stability, based on the combined use of steam ejectors and individual tubular condensers.
- High efficiency/low pressure drops structured packing in Vacuum Distillation and Final Fractionation, to reduce pressure drops and upgrade oil yield and product separation.
- Fixed blades Thin film evaporator to avoid coking and fouling.
- Special type of API pumps and instrumentation for critical services.
- All pumps doubled to avoid plant shut down in case of pump failure.
- Full DCS/PLC plant automation for continuous operation.
- Indirect heating of heavy streams to prevent fouling.
- Special mechanical design for thermal flexibility, vacuum operation and fouling services.
- Use of antifouling to reduce maintenance and cleaning operation.
- Proprietary design of Base Oil Finishing for Group I, Group I+ and Group II
