Sorbitol and Xylitol Pressure Reactor

The Sorbitol and Xylitol Pressure Reactor (LESXPR) is an industrial catalytic hydrogenation reactor for sorbitol and xylitol production. Nominal volumes run from 1,000 L to 30 m3, covered by models LESXPR 1000 to 30000, with design pressure from -1 to 200 bar and design temperature from -196 to 350 °C. The agitator is sealed by a magnetic drive, which suits reactions with tight sealing requirements and toxic or explosive media.

How it works

A magnetic coupling carries torque from the motor to the stirrer through a static seal, with no leakage. Couplings range from low to high torque. Motor power is 5.5 to 125 kW and stirring speed 200 to 400 rpm. The stirrer can be a flat blade turbine, a self-inducing impeller, a marine propeller or another type. Magnetic drives of this kind are applied to pressure reactions, reactions with noxious gases, potent pharmaceuticals and duties with zero leakage requirements.

Heating is by oil electric heating, oil heating or steam, with heating power of 3 to 90 kW. Product discharges from the top or the bottom. Listed materials are SS304, SS316, titanium, nickel, Hastelloy B/C, Monel, zirconium and Inconel, and the table also lists carbon steel and lined construction. At high pressure, clad plate can be used: a base material for strength and a clad layer for corrosion resistance. Larger sizes are designed and confirmed to the customer's requirements.
