Course Description

   
The success of every company depends of each employee's understanding of the business's key components. Employee training and development will unlock the companies' profitability and reliability.     When people, processes and technology work together as a team developing practical solutions, companies can maximize profitability and assets in a sustainable manner.     Distillation is the most common separation technique and is energy intensive. Distillation can consume more than 50% of a process plant’s operating energy cost.   

Away to improve an existing plant’s operating cost or to reduce a new distillation system’s operating cost is to improve the efficiency and operations by correct equipment selection, process optimization and control.   

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

Course Certificate  
Process & Control Academy certificate will be issued upon completion of the course.
