Olefins Cracking

The Petrochemical industry requires more and more propylene to meet the high demand for polypropylene. New processes have been developed to increase the propylene to ethylene ratio, because today, the primary source of propylene is as a by-product from ethylene production and ethylene demand is growing more slowly than propylene demand.

Axens Solutions proposes the FlexEne and Olicrack processes to produce propylene from olefin-rich light ends from cracking processes. These undergo an oligomerization step and are then easily cracked to produce propylene. This principle can be applied to different configurations depending on the required propylene production or the existing refinery scheme.
