Dear All, Recently a small furnace for the hydrotreatment unit was upgraded. The specific consumption changed from 20kgst/t to 14kgst/t. I would like to evaluate the return of investment from this upgrade. How do we convert kgst/t to kg/t. The combustible is fuel oil. The PCI is 9856 kcal/kg. The specific gravity is 0.95. Thanks
