 Introduction  

 

This course provides the theoretical and practical knowledge needed to efficiently and safely operate Merox units. The course covers process flow and equipment, unit operation, analytical procedures, maintenance procedures, and safety. To ensure the practical application of knowledge, discussion includes normal operations, startup, shutdown, and troubleshooting. Classroom lectures are combined with hands-on field exercises and question-and-answer time to allow participants to share operating problems they’ve encountered and discuss solutions. The course provides unique insight into the design and operation of Caustic and MEROX treating units. Over many years experts have gathered deep technical expertise in caustic treatment and processes. This knowledge and resulting best practices built the foundation for the course.

 

Training  Objectives

 

Upon completion of the course, participants will be able to:

  • Understand Merox Process chemistry and process flow
  • Identify common impurities and methods for their removal
  • Understand best practices for unit operation, startup, and shutdown
  • Develop effective techniques for solving problems
  • Best results are gained with the inclusion of participants operating data and problems into the discussions and exercises.

 

Training Methodology

 

This dynamic training course is highly-interactive & encourages delegate participation through a combination of lectures, group discussion, practical exercise, case studies, and breakout session designed to reinforce new skills. The comprehensive course manual has been designed to be practical, easy to use and facilitate learning. In order to help with establishing individual and business concerns, delegates will be asked to fill pre-course questionnaire.
