Abstract:

Primarily, safety in the design of chemical plants relies on the application of various codes of practice or design codes which are based on the wide experience and knowledge of professional experts and specialists in the industry. Such application is backed up by the experience of local plant managers and engineers who have been involved in similar plants and who have had direct experience in their operation. All new projects embody some element of change but in the chemical industry the degree of change from one plant to the next is often considerable. It-is important to recognise that the body of established experience expressed in codes, etc is limited by the extent of existing knowledge and can only be relevant to the extent to which it is possible to apply it to new products, new plants and new methods of operation involved in the new design. It has become increasingly clear in recent years that although codes of practice are extremely valuable, it is particularly important to supplement them with an imaginative anticipation of hazards when new projects involve new technology.

This study is intended to carry out HAZOP study of Propylene Recovery Unit in accordance with BS: 61882 & EPSC-HAZOP. The purpose of this report is to identify deviations from the design intent, identify potential hazards and operability problems associated with the deviations; and to recommend ways to mitigate the identified problems or to identify areas that need to be further investigated.
