Introduction

Hydrotreating and Hydrocracking Overview

Hydrotreating: Removes impurities (sulfur, nitrogen) from feedstock using hydrogen and catalysts.

Hydrocracking: Converts heavy oils into lighter products through cracking and hydrogenation.

 

Common Troubleshooting Issues

  1. Catalyst Deactivation: Leads to lower yields; consider regeneration or replacement.
  2. Pressure Drops: Check for blockages or leaks affecting throughput.
  3. Temperature Fluctuations: Inspect control systems and heat exchangers.
  4. Hydrogen Supply Issues: Ensure adequate hydrogen flow to maintain product quality.

 

Start-Up Procedures

  1. Pre-Checks: Inspect equipment and ensure feedstock/hydrogen availability.
  2. Gradual Heating: Slowly increase temperature while monitoring parameters.
  3. Feed Introduction: Introduce feed gradually with hydrogen.
  4. Stabilization: Monitor until conditions stabilize.

Shut Down Procedures

  1. Controlled Shutdown: Gradually reduce feed and hydrogen flow.
  2. Depressurization: Follow safety protocols to depressurize.
  3. Cooling: Allow the unit to cool down gradually.
  4. Final Checks: Inspect for maintenance needs before restart.

 

These concise steps help maintain efficient and safe operations in hydrotreating and hydrocracking units.

Objective

Upon the successful completion of this course, each participant will be able to:

Product Quality Improvement:

  • Enhance the quality of fuels by removing impurities (sulfur, nitrogen) and increasing octane or cetane ratings.

Maximize Yield:

  • Convert heavier fractions into more valuable lighter products, such as gasoline and diesel.

Catalyst Efficiency:

  • Maintain catalyst performance to ensure optimal reaction conditions and minimize downtime.

Environmental Compliance:

  • Meet regulatory requirements for emissions and product specifications, reducing the environmental impact of fuel production.

Operational Safety:

  • Ensure safe operation during start-up, shutdown, and normal processes to prevent accidents and equipment damage.

Cost Efficiency:

  • Optimize operating conditions and maintenance to reduce overall production costs.
