The process of flaring is a critical safety and quality procedure used in refineries and the chemical processing industry. Flaring occurs most often during start-up, shutdown, and process upsets such as power failures. During process operations, excess flammable and hazardous gases -comprised primarily of hydrogen, methane, and other hydrocarbons -are emitted by different types of plant equipment. These excess gases that cannot be recovered or recycled are burnt, resulting in the emission of carbon dioxide (CO2) and water vapour as an alternative to the direct release of the hydrocarbons into the atmosphere. The two main requirements of flares are the complete combustion of the gases and to ensure that these emissions are not visible.
