SCOPE OF WORK
The objective of the project was to comprehensively modernize and expand an existing ammonia cooling plant operating within an industrial facility. The scope encompassed engineering documentation, prefabrication of control cabinets, electrical installation work, and complete programming of the control system. The project was executed in collaboration with a company specializing in industrial cooling technology.
Given the strategic importance of the installation for the entire facility, a high-availability, redundant PLC system based on ControlLogix was implemented, featuring dual power-supply redundancy. Network communication was established using the PRP standard, ensuring continuous operation even if one communication channel fails.
The system was distributed using POINT I/O modules, and the drives were controlled through PowerFlex 755TL variable frequency drives (VFDs). The operator interface was developed in FactoryTalk View SE 13, offering complete process visualization and control.
As part of the project, full integration with the existing pumping station was achieved, ensuring consistent data, communication, and control logic between the new system and the existing infrastructure. An advanced pump and compressor management and sequencing system was also implemented, allowing for optimized equipment operation, reduced energy consumption, and an extended service life of the system.
