High Pressure Catalytic Hydrogenation Reactors for the Fine Chemicals

High Pressure Catalytic Hydrogenation Reactors for Fine Chemicals (series LEHPCHRFC) are industrial stirred pressure reactors built in volumes from 1,000 L to 80,000 L. Listed applications are oils and fats, fine chemicals, general chemicals, pharmaceuticals and hydrometallurgy.

How it works

Catalytic hydrogenation is usually a three-phase system: the solid catalyst is suspended in the liquid as a slurry and hydrogen is dispersed as gas bubbles. Mass transfer across the gas-liquid boundary, and hydrogen dispersion in particular, depends on the mixing system. The agitator is selected for the process: propeller, turbine, paddle, anchor, frame or helical ribbon impellers, driven at 0 to 1,200 rpm by a DC, DC servo or explosion-proof motor from 80 W to 125 kW through a magnetic or mechanical shaft seal.

Working pressure ranges from vacuum (-0.1 MPa) to 20 MPa and working temperature from -196 °C to 350 °C. Heating is by heat transfer oil, steam, electric, electromagnetic or far-infrared, at 3 to 90 kW. Charging is from the top and discharge from the bottom. Wetted parts are made from stainless steel 304, 316L, 310S or 321, duplex 2205, titanium, nickel, zirconium, nickel alloys C-276 and C-22, PTFE lining or clad plate. Internals (internal condenser, dip tube, thermowell, gas distributor, cleaning device, bottom bearing) and nozzles (manhole, liquid, gas and solid inlets, safety device, vent) are laid out per project. Overall height runs from 3,800 mm (1,000 L) to 9,100 mm (30,000 L); larger sizes are designed on request.
