This intensive and interactive three-day course is designed to address the operation and control of both fixed and variable speed centrifugal gas compressors and their drivers. Safe and efficient operation of a centrifugal compressor requires an good understanding of the compressor, the driver and their control systems. Most centrifugal compressors are driven by either gas turbines, steam turbines or electric motors and all three types of driver will be covered depending on the interest of the delegates.
The principles of operation, anti-surge control and start-up and shutdown will be key course topics. The most popular sophisticated anti-surge control system on the market is the Compressor Controls Corporation (CCC) system and the operation of this system will be covered in detail.
Suitable for: This course is designed for anyone involved with the operation of centrifugal gas compressors on any kind of processing plant. Operations personnel who have some level of responsibility for the operation, control or management of the gas facilities which contain centrifugal compressors will benefit most from this course.
