Visualization and control of the refrigeration process in Citrosuco's juice carrier Emily Oldendorff

September 21, 2023 | Reliance SCADA

Originally Brazilian, Citrosuco is a global producer of 100% orange juice, whose consumers can be found in over a hundred countries in Africa, America, Asia, Europe, and Oceania.

The company has five maritime terminals, which are in Santos (Brazil), Wilmington (USA), Ghent (Belgium), Toyohashi (Japan), and Newcastle (Australia), and a fleet of ships, which are five juice carriers and one multi-purpose vessel.

In 2023, Chiron-tec implemented a system for the control and monitoring of the cooling plant in Citrosuco's newest addition to its ship fleet – Emily Oldendorff. Currently, the 180-meter-long and 30-meter-wide ship is being converted from a cargo vessel into a juice carrier.

Control system

The system, which consists of three Siemens SIMATIC PLCs and the Reliance SCADA/HMI system, is used to control and visualize the refrigeration process and temperatures in the ship's sixteen tanks. It also controls and monitors the cooling plant's NH₃ detection and safety system.

The following special features are also part of the control system:

• Dual-monitor setup
• Temperature reports and settings
• Dynamic trending
• Digital and analog inputs/outputs
• Energy control
