Hazard Identification and Risk Assessment for a Refrigerated Propane Storage Tank- Part A

الملخص

The purpose of this paper is to apply risk assessment techniques on a propane refrigerated storage tank which represents a part of LNG recovery plant at Gdansk, Poland with the aim to contribute in making the operating processes as safe as possible. The paper starts with a general description of the process and considers some important past incidents that are similar and related to some extent to our process, and then conducts the analysis which is focused on a series of techniques that reveal the importance of safety and safety analysis. These methods were grouped according to the issues that they are investigating. For example, Hazard and Operability Studies (HAZOP) is the basic applied hazard identification technique in addition to Risk Ranking/Matrix and Human Errors whereas Fault Tree Analysis (FTA) and Event Tree are central techniques for a frequency analysis. Other methods such as Vapour Cloud Explosion (VCE) and Jet fire are chosen to illustrate the consequences and extend of impacts due to an undesired event. The study basically highlights the need for risk assessment in chemical process industries. However, since it is impractical to cover all these techniques at once, it has been decided to group them into two parts. In this part A, the hazard identification techniques are discussed whereas part B will be devoted for covering frequency and consequence analysis techniques.
