Abstract: For a chemical industry, risk associated with chemical processes is very high. Impact of those disasters is not limited to those industries alone. So, it is very necessary to evaluate the risk associated with the same. LOPA is semi quantitative methodology, which can be used to find out the risk of various processes in an industry. Our goal was to calculate the risk associated with the CHLORINE filling and storage tank and suggest some additional mitigation, if required
Chlorine is a toxic gas and can cause severe damages to human, aquatic, and animal life in the case of leakage. Splashes of liquid chlorine on the eyes and skin can lead to immediate irritation, chemical burns, and serious damage to the body tissues. Chlorine gas leaks are not uncommon in chlorine manufacturing industries while processing, handling, storing, and transporting, especially storing large quantities in big containers.
For completing this project, we have visited TRAVANCORE COCHIN CHEMICALS, Eloor and we got to know various safety systems associated with CHLORINE storage and filling station. Discussions were made with the experts from safety field and have clarified our doubts associated with the same. We referred some books regarding the LOPA technique from which we got valuable knowledge to complete the project.
After completing this project, we understood that the effect of this scenario is not only limited to the safety of an asset or safety of human being but also the impact of the same to the environment is very high. After evaluating the risk associated, we were successful to give out possible risk reduction methods required to minimize the impact to human being, assets and environment.
