Azzawyia Refinery is one of the biggest refineries in North West Libya, close to the city of Azzawyia. Due to its not optimized off gas utilization, a big quantity of refinery fuels gas was sent to flare, thus wasted, while on the other hand valuable diesel fuel was burned in the refinery’s heaters to cover the heat needs. Following GIT’s study, a number of changes were applied to the fired heater burners and to the off gas automatic control system, and other changes in the process. This way the gas burning to flare was minimized and there was significant saving in fuel consumption.
