See the attached file for more details Motivation: This project is motivated by the need for an automated safety system for the steam generating unit of a company. This system is required in the company following an accident that occurred in the company due to a miss communication between the maintenance and operation teams that resulted in collapse of a tank. A safety relief valve used to maintain pressure inside the tank was removed during maintenance and the operation team resumed operation before the valve was restored leading to a vacuum in the tank that leads to the collapse of the tank. By having a system to automatically monitor pressure inside the tank and alert the operation team in case of pressure imbalance, such accidents can be minimized considerably. In all industries, equipment such as motors, pumps, belts, gear trains and couplers are subject to wear and tear during use that would eventually result in an unscheduled shutdown. Cavitation one of the areas of interest of this research results in deterioration of the performance of pumps that may lead to failure of the pump. These unscheduled shutdowns lead to idle personnel and equipment that are usually expensive to maintain. By early detection of cavitation, these maintenance costs can be avoided. The motivation for this project, therefore, is to design a cost-effective, efficient system that automatically diagnoses pumps for degradation and cavitation to be able to predict pump failure thus decrease the large costs associated with idle equipment and personnel due to unscheduled shutdowns. Objectives: The main objective of this project is to develop a simulation of a system that would improve safety in a steam production unit by use of sensors interfaced to a controller which controls actuators such as valves and an alarm. This main objective would be based on an accident that happened in a steam production unit of the company. Another major objective is to design a system for automatically monitoring cavitation in a water pump. To achieve these objectives, research must be done on the safety measures that are currently used in a steam production plant of a chemical products company, possible areas and areas disposed to accidents should be identified, causes, effects and ways of detecting cavitation have to be investigated then systems designed to improve safety of the steam production unit and to monitor cavitation.

i have previously designed systems using PLC, and some of the systems were: 1. Level monitoring for two tanks. Clean dirty oil and pump it into a clean tank. 2. Crane Load Management: Here I used a PLC to monitor the lifted weight against the boom distance, and thus protecting the crane from damage, and increasing safety to all involved.. 3. Redundant propulsion PLC based systems on ships. There are many more, am sure I will be able to design a system to suite your appication. Regards,
