Our refining installed capacity is 1.1 MM bpd. 70% of this capacity is installed in Spain and the rest in several South American countries, mainly in Argentina. Most of our fuels produced in our five Spanish refineries are sold in local markets and hence they have to fulfil with the stringent European legislation. This paper shows the strategy followed by RepsolYPF during the last few years to adapt its refining structure in Spain to the production of clean fuels, and particularly to the production of ultra low sulphur diesel (< 10 wppm S). RepsolYPF is already producing 10 ppm sulphur gasoline and diesel oil for the Spanish market, as well as the regulated quality (50 ppm sulphur). As a starting point for this paper we take the situation in the year 2000: a new specification for diesel had just come into operation that limited sulphur in diesel to 350 ppm and all refineries had been adapted for this new spec. At this time an internal work programme was launched covering the following steps: 1- HDS industrial Units assessment, with the main objective of defining the real Units and refineries capacity to produce diesel with 50 ppm sulphur. The assessment included a detailed kinetic and process study carried out internally for all refineries, consultations to catalyst manufacturers and licensors and performance of test runs to a number of industrial Units. It was concluded that, considering the projects that were already in progress (one new HC and two new MHC units), four out of the five refineries would be all right for producing 50 ppms fuels. In the remaining refinery some shortage of HDS capacity was foreseen. At that stage it was decided that the additional HDS capacity to be installed should allow this refinery to produce 100% of its diesel auto with 10 ppm of Sulphur. After a technology selection process a new 24 kbpsd Unit was approved. 2- In parallel to 1) our Technology Division was asked to develop and provide the necessary tools for carrying out the internal studies required to adapt the refineries to the production of clean fuels. Through an extensive programme of pilot plant testing and analysis of industrial data, the following items have been obtained: - Kinetic models for ULSD production - Deactivation models for industrial HDS unit operation - Industrial Unit follow up model - Classification of commercial catalysts performance - General HDS unit simulation model 3- On view of the specs evolution (10 ppm fuels to be introduced gradually) a new assessment was launched to define the refineries capacity to produce simultaneously 50 and 10 ppm. 4- Finally, engineering studies were carried out for all the industrial units. These studies were the basis for definition of required revamps to adapt 100% of the production to the 10 ppm scenario. To carry out these studies, tools developed within 2) have been widely used, together with consultations to catalyst manufacturers and licensors. In this paper we describe the activities outlined above, with special attention to the industrial Units performance in the production of diesel with 50 and 10 ppm sulphur.
