Hazard and Operability Study in New Coal Chemical Department RSP & Indian Farmers Fertilisers Cooperative Limited, Paradip

Abstract

Hazard and operability study (HAZOP) is a technique to identify hazards and risks in a process industry and to bring it to a limitable level. In the presented paper Hazop study was applied on Coal Chemical Plant of Rourkela Steel Plant. In Coal Chemical Plant the gas which is sent to different equipment for separating unwanted chemicals from COG. Thus, gas which is obtained is being used as a useful resource for the production of other chemicals. Hazard and operability study is being applied to three nodes i.e. coke oven gas to primary gas cooler, electrostatic tar precipitator and exhauster. With the help of certain guide words, different deviations were obtained for which suitable safeguards were taken. Hazop is a time taking process but helps in improving process safety and eliminations of risk to a tolerable level. Thus, it is necessary to identify hazards and risk associated with it using certain guide words and with best efforts it can be decreased to a limiting level.
