START DATE: 08 Apr 2018

END DATE: 12 Apr 2018

UNIT: 5 days

  • COURSE TYPE: Oil & Gas Engineering & Technical



o Course Objective

This course will guide the participates to develop key concepts and techniques to design, operate and troubleshoot a distillation system, with an introduction to simulation software. These key concepts can be utilized to make design and operating decisions.    

o    Training and development is an investment in future success - give yourself and your employees the keys to success.  

o    Product recoveries, purities and energy utilization can be improved in most distillation systems. This cannot be achieved without first an understanding of distillation principles and design.

*These principles need to be understood in advance of designing, operating and trouble shooting a distillation column for the operator, designer, or problem solving to be effective.
