Course Description
This 5-day course will be dealing with the Cracked Gas Compressor and its driver “steam turbine” operation controls, troubleshooting and other related operational issues such as fouling, leaks, emergency shutdown, trips, process safety and start-up permissible.
The cracked gas compressor is one of the most critical pieces of equipment in an ethylene plant and may be the limiting factor in ethylene plant performance optimization. The high potential for severe fouling leads to deterioration of plant performance with associated significant economic penalties in energy and productivity losses.
This training course will empower participants with detailed information and knowledge necessary to thoroughly understand the cracked gas compressor operation and control and will also provide participants with the necessary experience and confidence to work in any organisation requiring assistance and experience in cracked gas compressor operation and control.
By undertaking this course, participants will be able to independently drive and oversee cracked gas compressor operation and optimization and contributing to a significant responsibility and function for their organisation.
Course Objectives
- Recognize centrifugal compressors working principles for successful operations of your plan
- Optimize the operation efficiency of your compressors
- Realize centrifugal compressors construction details
- Apply the best practices and guidelines for operation problem solving and troubleshooting
- Analyze the problems in operation related to Surge and Fouling
- Undertake critical action that would save the organisation maintenance and operational costs
- Conduct regular checks and inspections to ensure that gas compressors are working at optimal efficiency and quality
- Provide adequate confidence and knowledge to train other professionals on best practices and precautions
Who Should Attend?
- Plant Operation & Maintenance teams
- Operation Engineers, Supervisors, Team leaders
- Process engineers, Inspection and Reliability Engineers
- Engineers and supervisors concerned with safety, optimization and operating issues of the cracked gas compressor.
