Benzene Hydrogenation

Benfree® C

When limiting the benzene formation in the reformer is not sufficient to meet gasoline pool specifications, Benfree® C engineering design services will provide a reliable solution to adjust the benzene saturation to requirement. The conventional option consists of a hydrogenation unit downstream of a reformate splitter to saturate the benzene contained in the light reformate stream. The unit utilizes a highly active catalyst that is operated in the liquid phase under mild conditions to minimize investment cost.

Benfree® RD

The Benfree® RD integrates an external fixed bed hydrogenation reactor with the reformate splitter column, therefore reducing equipment and associated costs to save capital cost and plot area. The light reformate product is withdrawn as a side draw of the column for RVP control. Operating conditions are adjusted to minimize the toluene carry-over to the hydrogenation reactor thus minimizing the octane loss.

Solvent hydrogenation

Axens’ Solvent hydrogenation unit uses a highly active catalyst and operates in the liquid phase under mild conditions to minimize the investment and operating cost.

The Axens Solvent Hydrogenation technology covers alternative configurations, with main reactor and/or a polishing reactor as function of the expected specifications
