Process industry continues to be of central importance to the global economy. At the same time refineries are also large, complex sites with many processes, several of which operate at very high levels of pressure and temperature, and a vast pipeline to transport process fluids throughout the site and eventually to external modes of transport.  This combination of factors make refinery sites very vulnerable to a variety of corrosion phenomena that can eventually cause a loss of containment of process fluids, sometimes leading to a serious accident affecting workers, the environment, the surrounding economy and even on occasion the larger economy. This study of corrosion-related accident in refinery is based on important refinery accident in which corrosion of an equipment was identified or suspected as being the key failure leading to the accident event. In this paper, lower explosion limit, LEL, upper explosion limit, UEL, and maximum explosion pressure of coke oven gas measured in 20 dm3 explosion autoclave at 20 °C and 101 kPa, are presented in this paper. Furthermore, the presented measured values at 1.0 bar, 0.75 bar and 0.5 bar and temperatures 323 K and 373 K.
