General Overview
 Start Up:
1976
 Shut Down:
1997
 Capacity:
6500 tons per year (22 tpd of 40% solution)
 The plant also consists of the following:
• (3) 700 liter, hydrogenation reactors/autoclaves
(vertical tube reactors)
• H2 Electrolysis Plant
Process Description
 After the glucose is dissolved, the catalyst is added to the solution and
the pH value is adjusted.
 The solution is then transported by dosage pumps into autoclaves.
 Under high pressure and temperature, hydrogenation is performed in
three steps:
o The catalyst is removed from the prepared 40% solution of Sorbitol
through decantation (1st step) and centrifugal separation (2nd step).
o Nickel+2 is then removed by ion exchange (3rd step)
 The prepared solution is stored in vessels for use in the production of
Ascorbic Acid synthesis, or it is transported to the evaporation unit for
use in the production of 70% Sorbitol solution and Sorbitol crystallized
by fluid bed granulation
