Polymerization - Ekato

In the reactor cascade, the heat of polymerization is removed by evaporating the styrene monomer. The gaseous monomer is then condensed and fed back into the reactor. This type of heat removal requires high homogeneity and good surface entrainment. For this reason, these reactors are often equipped with the Ekato Paravisc.

Polymerization - Wikipedia

The semi-batch polymerization reactor considered in this study consists of a jacketedvessel with a stirrer motor, one stream for vapor releasing and another to collect the final product (Figure 1). The feed consists of the monomer ε-caprolactam (CL),water (W) and acetic acid (AA), used as chain terminator. Vapor stream is composed by CL, W and AA.

Designing Polymerization Reaction Systems | AIChE

Polymerization reactors are rarely built to make only one product over the entire life of the equipment. Normally, a reactor switches among a handful of products. In addition, markets change, so manufacturers prefer a flexible design — one that is good today, and, with little or no modification, 30 years from now. Reactor configuration.

Batch reactor - Wikipedia

The batch reactor is the generic term for a type of vessel widely used in the process industries.Its name is something of a misnomer since vessels of this type are used for a variety of process operations such as solids dissolution, product mixing, chemical reactions, batch distillation, crystallization, liquid/liquid extraction and polymerization.In some cases, they are not referred to as .

The Influence of Residence Time Distribution on Continuous .

Continuous-flow chemistry is emerging as an enabling technology for the synthesis of precise polymers. Recent advances in this rapidly growing field have hastened a need for a fundamental understanding of how fluid dynamics in tubular reactors influence polymerizations. Herein, we report a comprehensive study of how laminar flow influences polymer structure and composition.

Radical polymerization - Wikipedia

Free-radical polymerization (FRP) is a method of polymerization by which a polymer forms by the successive addition of free-radical building blocks. Free radicals can be formed by a number of different mechanisms, usually involving separate initiator molecules. Following its generation, the initiating free radical adds (nonradical) monomer units, thereby growing the polymer chain.

On the Mathematical Modeling of Polymerization Reactors .

Abstract As commercially produced polymers become more of a commodity product, rather than a specialty product, there is a growing need for a more detailed understanding of the phenomena taking place in the polymer reactor. One quantitative form of this process understanding is the mathematical model, which can represent the detailed behavior of a polymer reactor.
