Chemical reactor - Wikipedia

A loop reactor is a hybrid type of catalytic reactor that physically resembles a tubular reactor, but operates like a CSTR. The reaction mixture is circulated in a loop of tube, surrounded by a jacket for cooling or heating, and there is a continuous flow of starting material in and product out. PFR (plug flow reactor)

Tubular Plug Flow Reactor These are perhaps the simplest form of polymerization reactors. The monomer reactant mixture is forced through a pipe where the reaction occurs along the pipe length, and as polymers tend to be very viscous, the system can be assumed to be in the laminar regime. Ideally, monomers in a theoretical slice of the stream .

Plug Flow Reactor

Plug Flow Reactor (PFR) The third general type of reactor is the Plug Flow Reactor (PFR). In a plug flow reactor, nutrients (and sometimes organisms) are introduced to the reactor continuously and move through the reactor as a "plug". The system may be either contained (as in a water main, oil pipeline, or blood vessel) or open (as in a .
