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
