Introduction

TRAINING DESCRIPTION

This intensive course emphasizes process selection, practical operating issues, technical fundamentals, and integration of the Sulphur recovery block units into the overall scheme of a refinery. The key elements associated with the design, operation and control of refinery Sulphur recovery unit (SRU), tail gas treating unit (TGTU) , amine regeneration unit (ARU) and sour water stripping unit (SWS) will be thoroughly covered in this course.

 

The course includes practical worked examples and case studies to reinforce the key learning.
