The batch charge and slurry catalyst are continuously pumped through an external heat exchanger to the HH Jet Mixer in the top head of the HH Loop Reactor (Figure 1). The nozzle acts as an eductor, and the action of the slurry passing through creates intimate gas/liquid/solid mixing

The chemical reaction takes place primarily inside the HH Jet Mixer in a well-defined impact zone prior to the gas/liquid disengagement at the Jet Mixer exit. Mass transfer rates are superior to conventional stirred reactors (5 to 10 times better). In the continuous operation mode, the mass transfer rate is increased to even higher levels.

The design of the HH Jet Mixer is adapted such that the HH Loop Reactor system is either under a high gas distribution or under a low gas distribution depending on the specific reaction. The distinct features of the HH Loop Reactor of clearly separated mixing, pumping, and heat removal capacity allow for simple and reliable equipment scale-up with the help of pilot plant tests and simulation programs.
