This paper deals with the development of reduced models of a hydrodesulphurization plant oriented to computing the dynamic hydrogen consumption rates as a function of the plant load. This is part of a wider project oriented to the optimal management of the hydrogen network in a petrol refinery. The proposed models are of hybrid nature, combining physical-chemical principles with black box elements. The paper describes the structure of the models as well as the procedure of calibration and maintenance with real data from the process.
