Risk Assessment of Tobruck Seawater Desalination Plant Based on Hazard and Operability Study Approach: A Case Study

الملخص

Operation processes in desalination plants are full of several risks that are difficult to predict, which may cause their failure or poor performance, for this reason become obliged to manage these risks with scientific methodology to detect the risks. This study aims to assess the operational risks of the Evaporator and its accessories in the General Company for Desalination-Tobruck- by using HAZOP technology to examine the process and review the design. The risks were identified by the basic elements of the operation process using guiding words as well as setting the probability and consequences for each deviation with the use of the risk matrix to evaluate the risks. The results showed that many high risks, most notably the risk of high pressure, temperature, increasing of scales in the evaporators and boilers, also increasing noising in the evaporators unit, and clarify the appropriate ways to control or reduce their severity. In this study, two experts from the Tobruck desalination plant and five operators were used to collect data and identify risks.
