Reaction vessels which perform hydrogenation reaction are known as Hydrogenators. A prominent function of hydrogenator which often determines the product quality is the degree of dispersion of hydrogen gas in the given liquid reaction media. Thus this reactor has to be designed very carefully Elgin has designed several hydrogenators for Vamshi Chemicals and for SPIC SMO.

The induction hydrogenator has a hollow shaft with small apertures at the top .Hydrogen gas enters these holes usually through self aspiration and is discharged as small bubbles through the spargers present on the impeller itself.

The hydrogenators manufactured by Elgin have the following advantages:

•  Uniform and powerful gas dispersion insures greater interfacial area for mass transfer.
•  High Hydrogen gas recirculation rate.
•  Uniform catalyst suspension in case of solid catalyst/slurries.
•  Catalyst savings and longer catalyst life.
•  High product quality.
•  No fouling.
•  Non limiting heat transfer.
