Abstract

This method for providing guidance for operation of a residual hydro desulfurization process includes the steps of: obtaining target quality information of an oil refining product; determining values of controllable operating parameters in a residual hydro desulfurization process so as to maximize a value of an objective function derived by subtracting costs incurred in refining a target flow rate of an oil refining product from a profit that can be calculated on the basis of the target flow rate of the oil refining product; and providing an optimal operation guidance of the residual hydro desulfurization process through a user interface on the basis of the determined values of the controllable operating parameters.
