EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

During the steel making process, huge quantities of gas are produced, stored and used as fuel later on in the process. It is the case of the Coke Oven Gas (COG), the Blast Furnace Gas (BFG), the Basic Oxygen Furnace Gas (BOFG) and the Corex Gas. Those gases contains high percentages of Carbon Monoxide (CO), which is very toxic at low concentrations and also odorless and colorless, which makes them undetectable to human beings. Many accidents occurred every year due to CO leaks. Even though many safety measures has been put in place, according to the world steel association, gas and asphyxiation is one of the five main causes of fatality in the steel industry. Gas Odorization is a proven technology, used globally for the distribution of Natural Gas and Liquefied Petrol Gases (LPG), which are highly explosive, just by adding a warning agent that makes them detectable in case of leak. Over the past decades, Arkema has developed a strong expertise in this field and enjoy today a leading position for the production and supply of gas odorants. This technical paper explains the basis of gas odorization technology as well as its implementation for the toxic gas detection in the steel plants.
