Resumen del autor, extraído del trabajo. The year 2010 + refinery will be market driven and will have to face with continous features: a more stringent fuel reformulation (sulphur, aromatics, ...), severe environmental limitations for operations, and in view alternative transportation fuel breakthroughs. Crude supply optimisation will be the first but limited way to do it. In 2010 and in the subsequent following years, the refining industry will still be practically the sole contributor to the production of transportation fuels, with more than 95% of the demand still supplied at that time by the refiner. Meeting the growing demand for such products not only in terms of volume but also in terms of products quality shall have required a very significant evolution of the present refining tool, materialized by an increased complexity. However it is anticipated that such complexity will not be needed for those refineries which have specific niches or preferential locations. The refining industry has at its disposal the necessary technological support to supply the market with high quality products; facing the foreseeable development in the medium term of new types of car engines and alternate fuels, this ability to keep providing clean transportation fuels is a "must" for the refiner. Further products specifications and emissions directives which are likely to be imposed by the authorities should however reflect a global approach of the environmental problems.
