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)

Plug flow reactor model - Wikipedia

Fundamentals of Chemical Reactor Theory1

A Plug Flow Reactor (PFR) consists in a long, straight pipe in which the reactive fluid transits at steady-state (no accumulation). The main assumptions of this model are that the fluid is completely mixed in any cross-section at any point, but it experiences no axial mixing, i.e. contiguous cross-sections cannot exchange mass with each other.

Tubular Reactor Features | Vapourtec Ltd

All Vapourtec tubular reactors contain a coil housed inside an insulated glass manifold. Temperature can be easily controlled by circulating heated or cooled air around the reactor. Coil tubular reactors, therefore, do not need to be wound tightly round any sort of former to achieve thermal conductivity.

Plug flow reactor model — Wikipedia Republished // WIKI 2

The plug flow reactor model (PFR, sometimes called continuous tubular reactor, CTR, or piston flow reactors) is a model used to describe chemical reactions in continuous, flowing systems of cylindrical geometry. The PFR model is used to predict the behavior of chemical reactors of such design, so that key reactor variables, such as the dimensions of the reactor, can be estimated.

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 .

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 .
