Centrifugal and reciprocating Compressors play a very essential role in many petrochemical and industrial plants. Centrifugal compressors in general runs at very high speeds, exposed to high temperature. The compressor operation is confined between the Surge and Stonewall limits.

The reciprocating compressors in general run at low speeds to avoid any mechanical stress because the compressors contain many rotating parts.

The compressor performance also is affected by the variation in operating conditions. Elevated temperature and large centrifugal stresses make the gas turbine operating under very critical conditions requires very complicated monitoring and protection systems. The above very sever operating conditions enhances the machines deterioration. Accurate instrumentation, monitoring, troubleshooting and maintenance programs are essential for maintaining and increasing the available time of the machines. Understanding and learning Reciprocating and Centrifugal compressors more deeply help smooth and free trouble operation.

During the course the protection and control system are going to be addressed thoroughly. Parameters affects the above will also be discussed during the course.

The condition monitoring for reciprocating and centrifugal compressors as on line and off line will discussed during the course.

This course is designed to improve skills and confidence of Operation staff. By the end of the course you will learn:

• Regulation of the compressor system to maximize efficiency whilst accurately meeting process control objective requirements.
• A load sharing scheme utilizing equidistance from surge, to maintain the main process variable (suction header pressure) whilst minimizing recycle and maximizing the operation envelope.
• High discharge pressure limiting by reducing the speed of the gas turbine and finally by the opening of the antisurge control valve.
• Protect each section of the compressor from surge-induced compressor damage and process upsets with minimum recycle. Minimize process upset resulting from recycle control.
• Minimize adverse interactions between the above control functions.
• Automate changes in the process status by implementing startup, shutdown, and purging sequences.
• Integration with a distributed control system, instrument protective system and (where fitted) data acquisition system.
• Prevent unnecessary process trips and down time
• The capacity control for reciprocating and centrifugal compressors
