Reactor parallelization

Adiabatic plug flow reactors operate under the condition that there is no heat input to the reactor (i.e., Q = 0). The heat released in the reaction is retained in the reaction mixture so that the temperature rise along the reactor parallels the extent of the conversion. Adiabatic operation is important in heterogeneous tubular reactors.

Tube Reactor, Parallel Flow A sketch of this reactor configuration is shown in Figure 17. Here the reactant gas or gas mixture flows axially down a tube (circular or rectangular cross section) over a heated susceptor... 

Description The Hostalen process is a slurry polymerization method with two reactors parallel or in series. Switching from a single reaction to a reaction in cascade enables producing top quality unimodal and bimodal polyethylene (PE) from narrow to broad molecular weight distribution (MWD) with the same catalyst.
