Abstract:An oil refinery needs fuel gas to burn in furnaces and boilers to meet its requirements for process heat and steam. Normally this is either imported natural gas or vaporized LPG. The Rotterdam Refinery of ExxonMobil differs from other refineries in the sense that it usually has a fuel gas excess instead of the normal shortage and has no import requirement. This is the consequence of the ability to upgrade heavy residuals by means of a Flexicoker. Since the fuel gas balance fluctuates over time a prediction needs to be made of supply and demand by using a fuel balance application. Previous fuel balance applications are depreciated due to refinery changes, lack of flexibility or missing functionality. A new fuel balance application is developed in Excel and Access with robustness and flexibility in mind. Exemplary fuel balance cases are used as verification for the required functionality.
