Hydrogenators

Advantages

• Optimal contact between dextrose, hydrogen and catalyst
• Optimal utilization of catalyst
• Easy test sampling during production
• Working pressure and temperature adapted to provide shorter reaction time
• Resistant against tear and wear
• Different sizes. Production capacity from 700 kg/h to 2,000 kg/h

Characteristics

• Batch-wise hydrogenation
• Special agitator designed for high circulation rate.
• The Hydrogenator is designed to give optimal conditions for agitation (height/diameter relation, baffles etc.)
• Special sampling system, which allows sampling even at highest pressure and temperature.
• Combined heating and cooling coil with high efficiency.
• All parts in contact with the product are made of stainless steel.

Technical Specification

The DSSE Hydrogenator is developed for hydrogenation of dextrose to sorbitol. In the Hydrogenator a dextrose solution (DS 50%), containing an activated nickel catalyst, is heated and exposed to hydrogen under high pressure. The DSSE Hydrogenator works under a pressure of approximately 50 bar (g) and a temperature of 140ºC. The process is batch-wise and the total time per charge amounts to 5-8 hours depending on the process design.

The reaction takes place theoretically as follows:
C₆H₁₂O₆ + H₂ -> C₆H₁₄O₆ + 57.4 kJoule/kmol
