Hazard and Operability Study in New Coal Chemical Department and Risk Assessment in a Food Processing Industry

Abstract

Hazard and operability study (HAZOP) is a technique to identification of hazards is involving in the process based on guide words and give recommendation for control of risk. To identification of hazards in the coal chemical department of steel industry by using HAZOP study technique. The studies carried out by a multidisciplinary team for. Explosive hazards, toxic hazards and toxic hazards are main three hazards in any process industry. The Hazard and operability study is the identification of Hazards in process of any industry and find out the lack of safety in the industry. Coal chemical plant is the by product for coke oven gas. The gas is sending through different equipment’s for removal of the plant and also helps to improve process safety and to eliminate potential hazard points. HAZOP study is a time consuming process which can compromise the quality of the work different chemical components from the coke oven gas. The functions of the by-product plant are removal of all un wanted chemicals from the coke oven gas and which chemicals removed from the coke oven gas those are useful chemicals for different uses. Hazard and operability study conducted for three different nodes are coven oven gas from battery to before entrance of primary cooler, primary cooler, electrostatic tar precipitator and found out many deviations by apply of suitable guide words. Many hazards are involving in the by-product plant and these hazards are effecting the environment, process and the human beings. The Hazard and Operability Study conducted on the coal chemical plant serves to identify the lack of safety and suggest the preventive controls to eliminate all potential hazards in the process industry.
