Refinery

Refining unit: It is on those different treater units that one product becomes another one by chemical reaction (distillation, hydrotreater, isomerization,...). Blending unit: Intermediate products from refinig units are scarcely commercialized and can not be sold. To be sold, they have to be blended in variable proportions according to technical specifications of finished products. Storage: In every production site, at the start and the end of the pipe-line and refining unit, there is storage. The storage number depends on the complexity of the refining unit.
