Desenvolvimento de um sistema de controlo e eliminação de fugas de Amonia na planta de refrigeração da Coca-cola Moçambique

Abstract

The purpose of this work is to integrate three systems into the Coca-Cola Mozambique refrigeration plant: the refrigeration control system, the ammonia detection system and the emergency ventilation and exhaust system. According to the results obtained in the Siemens LOGO LADDER simulation, the integration enabled actions such as shutting down ammonia valves and triggering fans and exhaust fans and emergency alarms to be carried out automatically. The implementation of the safety system against ammonia leaks will provide the plant operator with a danger alert in relation to the work area, as well as helping the utilities maintenance team to eliminate leaks in the plant in order to guarantee efficient operation and operator safety.
