Overcoming The Challenge Of Dienes In The Cracked Naphtha

One of the biggest challenges to the crude oil refining industry in the last decades was the development of technologies capable of reducing the environmental impact of the derivatives while raising the performance of these compounds.

The hydro-processing technologies allow the production of cleaner and better performance derivatives while simultaneously making possible the recovery of higher yields of added value products from bottom barrel streams in the crude oil refining.

The value addition to naphtha streams is especially hard in some cases, mainly to the streams produced by deep conversion processes like Fluid Catalytic Cracking (FCC).

Despite the current trend of reducing transportation fuel demand, some markets still present significant dependence on these crude oil derivatives to sustain economic development; this is especially true in developing economies like Brazil.

The production of high-quality gasoline is still fundamental to crude oil refiners aiming to meet the market demand. Considering the current specifications, the synergy between Fluid Catalytic Cracking units (FCC) and Cracked Naphtha Hydrodesulphurization is fundamental to allow the refiners to reach profitable operations, mainly in markets with high demand transportation fuels.
