Introduction to Downstream Petroleum Industry

Presenter: Raj Hajjarya

• Technical Manager at GTA
• Objective: High-level familiarization with the downstream industry.

Overview of Downstream Industry

• Upstream: Discovery and extraction of crude from underground.
• Downstream: Processes from the surface onward, including refining, petrochemical production, transportation, and marketing.
• Supply Chain: From refinery to storage, transportation to consumers, including homes and industries.

Refining Fundamentals

• Crude Oil: Mixture of hydrocarbons, impurities like sulfur, nitrogen, metals.
• Sweet vs. Sour Crude: Based on sulfur content.
• Refined Products: Gasoline, diesel, kerosene, etc.
• Refining Processes:
  • Separation: Distillation of crude into components based on boiling points.
  • Cracking: Breaking down larger molecules into smaller ones.
  • Alkylation & Reforming: Combining smaller molecules or changing molecular structure.
• Byproducts and Value: Impurities and residues can have market value, e.g., sulfur, coke.

Petrochemical Production

• Inputs: Ethane, propane, butane, etc.
• Products: Plastics, chemicals like polyethylene, polypropylene.
• Usage: Everyday products including cosmetics, detergents, and more.

Gas Processing

• Natural Gas Uses: Cooking, heating, power generation.
• Components: Methane, ethane, propane, butane.
• LNG, LPG, NGL: Definitions and differences.
• Gas Plant Functions: Remove impurities, separate valuable components.

Safety, Health, and Environment (SHE)

• Hazards: Fire, explosion, chemical leaks, and emissions.
• Environmental Impact & Mitigation: Wastewater treatment, air quality monitoring, reducing CO2 emissions.
• Safety Measures: Hazard assessments, root cause analyses, automatic safety systems.
• Regulations: Compliance with international codes and standards.

Industry Challenges

• Market Dynamics: Demand fluctuations, e.g., COVID-19 impact.
• Refinery Margin Business: High capital and operating costs, competitive market.
• Insurance: High-cost capital requires complex insurance strategies.

Conclusion

• Session Goal: Familiarization with downstream industry terms and processes.
• Q&A Highlights: Clarifications on refining processes, insurance complexities.

Additional Notes

• Videos & Visuals: Included for further understanding of processes.
