Summary and Final Tasks

Summary

Supporting processes are essential to the operation of a refinery. These processes have become more important as the crude oil base has become more sour. The demand for hydrogen has increased to support the required finishing processes for heteroatom removal and recovery of sulfur and metals. Refineries have become major producers of elemental sulfur for the chemical industry.

Learning Outcomes

You should now be able to:

• outline and assess the processes for acid gas removal and elemental sulfur recovery from H₂S;
• discuss and illustrate sources of hydrogen and hydrogen production processes;
• assess primary water toxicants and waste water characterization parameters, and outline waste water treatment processes.
