Course Content

CLASSIFICATION & PROPERTIES OF BASE OILS

0.25 day

  • Commercial lubricant function and composition, purpose of additive introduction, demand structure.
  • Mineral base oil classification, market trends.
  • Main quality criteria in relation with chemical composition, specifications.

STRUCTURE OF BASE OIL MARKET

0.25 day

  • Market demand in relationship with uses of lube oils.
  • International market and future trends in main developing countries.

BASE OIL MANUFACTURING SCHEMES

0.25 day

  • Composition of vacuum distillates and residue: influence on refining.
  • Conventional manufacturing scheme vs. base oil manufacture by hydrotreatment: units’ purpose, products quality.

BASE OIL CONVENTIONAL REFINING PROCESSES

0.75 day

  • Vacuum distillation:
  • Residue fractionation: distillates yields depending on crude oil.
  • Operating conditions. Quality control: viscosity and flash point tuning.
  • Solvent extraction:
  • Vacuum residue deasphalting and aromatics extraction: solvent choice, operating variables, viscosity and VI control.
  • Solvent recovery, energy consumption.
  • Solvent dewaxing:
  • Paraffin crystallization in the presence of a solvent: operating conditions.
  • Specific equipment: chillers, rotating filters.

BASE OIL UNCONVENTIONAL REFINING PROCESSES

1.5 days

  • Hydrotreatment processes:
  • Typical process flow diagram - Main equipment: reactor, heaters, heat exchanger.
  • Chemical reactions and catalyst for hydrotreating.
  • Operating conditions: pressure, temperature, hydrogen ratio, WABT.
  • Impact of conditions on quality: pour point, viscosities, VI, CCR…
  • Hydrorefining: hydrocracking of vacuum distillates and deasphalted oil.
  • Hydrodewaxing: hydroisomerization of slack wax/gatsch.
  • Hydrofinishing:
  • hydrofinishing of lube basestocks, paraffins and microwaxes,
  • white oils manufacturing principles: required properties.
  • Operation and troubleshooting:
  • Impact of the operating parameters on yield and product quality, tuning and optimization.
  • Adjusting the operating conditions to compensate for variable feed quality and the ageing of the catalyst, monitoring the activity of the catalyst.
  • Study of the industrial risks of this operation.
  • Disturbances and incidents.
Ways & Means
  • Detailed course material with a glossary of the main technical terms used in the refining industry.
