How does PFR work?

PFR is an idealized flow reactor such that along the direction of the flow all the reaction mixture are moving along at the same speed; there is no mixing or back flow. The contents in the PFR flow like plugs, from inlet to outlet.

Why PFR is used for gas phase reaction?

Gas Phase Reactions The tubular reactor (i.e., plug-flow reactor [PFR]) is relatively easy to maintain (no moving parts), and it usually produces the highest conversion per reactor volume of any of the flow reactors.

How is plug flow achieved?

Theoretically plug flow could be achieved by two methods: a) using a number of CSTRs in series, or b) operating high net flow Reynolds numbers in a tubular reactor. Achieving the ideal plug flow requires an infinite number of CSTRs, which is impossible.

How does tubular reactor work?

The tubular reactors work on the principle of continuous flowing systems in a cylindrical geometry. First you will introduce a fluid or fluids that you intend to mix with other reactants into the tubular reactor. As the fluids of reactants flow through the tube or tank, there is a chemical reaction that takes place.

How does a chemical reactor work?

In general, in semibatch operation, one chemical reactant is loaded into the reactor and a second chemical is added slowly (for instance, to prevent side reactions), or a product which results from a phase change is continuously removed, for example a gas formed by the reaction, a solid that precipitates out, or a …

What is the other name of series reaction?

In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their “reactivity” from highest to lowest.
