Gas Sweetening & Sulfur Recovery Course

Course Description

In this course, you’ll get acquainted with various types of gas sweetening & sulfur recovery processes. You’ll learn about the amine treating units, different types of amines (MEA, DEA, MDEA, etc.), and their differences and pros and cons. Knowing more about the process flow diagram of a typical amine treating unit is another topic that will be touched. Understanding the common operational problems ( e.g. foaming, degradation, corrosion) and the design considerations in an amine unit is another topic. Sulfur recovery processes and the way to choose the most suitable one and knowing more about the Claus unit, incinerators, and the SCOT tail gas handling unit are also covered in this course.

This course is suitable for chemical engineers, mechanical engineers, plant operators, plant engineers/managers and project managers who work in oil & gas industry
