At the conclusion of the preliminary studies, the selected configuration consists in increasing the capacity of the atmospheric distillation unit and the construction of a unit in order to maximize the production of gasoline. In addition, a new vacuum distillation unit will be built. This unit will make it possible to produce a cut of distillate which will be used in the new hydrocracking unit.

To maximize the reliability rate of the whole refinery, a new electricity production unit will be built in order to replace the three diesel groups under operation since the creation of the refinery. The electrical production will thus pass from 9 to 16 megawatts. The increase in the utilities necessary for the operation of the units has also considered.
