Total Hydrogenation

Total hydrogenation aims in optimizing the co-cracking of various streams that are worth being sent back as feedstock to the cracker furnaces. Alternatively, it can also aim in producing cuts that can be used as LPG.

Axens Offer

Axens can offer all kind of configurations for either single or mixed cuts, such as:

C3 Total Hydrogenation
C4 Total Hydrogenation
C4-C5 Total hydrogenation

Through total hydrogenation, the characteristics of the cut for co-cracking are optimized towards better ethylene yield, lower coking of the cracking furnaces as a result of the full elimination of diolefins.

To date, when butadiene is extracted, relying on the raffinate’s total hydrogenation is an excellent way to further improve the co-cracking feed quality. It can also be an option of choice when the amount of crude C4 is too small to make the implementation of a butadiene extraction economically interesting.

Total Hydrogenation (C₃, C₄, C₅ cuts)

Axens Total hydrogenation technologies answer the need for olefines bulk removal to produce a co-cracking recycle stream to specification.

A low residual olefins content in co-cracking stream is necessary to mitigate the negative effect of feed olefines in steam cracker furnaces.

Axens Total Hydrogenation technology typically includes a main reactor with an internal recycle. However, for more stringent needs, this technology might be configured with a finishing reactor to comply with very low olefins residual content, mainly when thriving to reach LPG product quality.

Axens total hydrogenation technologies can be configured to operate on alternative operating mode: total or selective. In addition, this technology can be revamped into selective hydrogenation, even after several year of operation, to support a product shift strategy.

Total Hydrogenation Catalysts

Axens total hydrogenation catalysts are recommended for the hydrogenation of hydrocarbon cuts to lower the aromatic content or to saturate olefins and diolefins. They offer high resistance to poisons when the feed contains a few ppm of sulfur or of other contaminants.
