The two fluids to be reacted mix and flow through a pipe that is stuffed full of catalyst. The length of the pipe depends on the desired conversion of product. A recycle stream can be added to mix with the incoming feed if desired. Also one or more of the reactants can be added at different points in the reactor if desirable. If the reaction is exothermic a cooling mechanism will be needed to reduce thermal stress on the reactor walls and/or keep the reactor operating at the desired temperature.
The overall basic difference is the ability to obtain widely varying performance for the reactor depending on the amount of recycle sent back to the plug-flow reactor (PFR).The equations do not lend themselves to typing. For a comprehensive overview of the subject see p.296-297 of Chemical Engineering Kinetics & Reactor Design by Charles G. Hill.

The Feed conditons entering are at 25 deg c with 101.3 kpa the reactor is a cstr operating at 65deg c the product if ethylene glycol!!!!!!
The plug flow reactor model (PFR, sometimes called continuous tubular reactor, CTR) is normally the name given to a model used in chemical engineering to describe chemical reactions in continuous, flowing systems of cylindrical geometry.

A plug valve controls flow using a cylindrical or conically tapered plug, providing quick open and close operation. A needle valve controls flow with a long, tapered needle that fits into a seat, allowing for precise flow regulation in applications requiring fine adjustments.
The fluids to be reacted mix and flow through a pipe that is stuffed full of catalyst. The length of the pipe depends on the desired conversion of product (the longer the pipe, the greater the % conversion.) The pipe diameter depends on the desired capacity of the reactor. A recycle stream can be added to mix with the incoming feed if desired. Also one or more of the reactants can be added at different points in the reactor if desirable. If the reaction is exothermic a cooling mechanism will be needed to reduce thermal stress on the reactor walls and/or keep the reactor operating at the desired temperature.
For simple understanding PFR can be imagined as multiple CSTR's in series. PFR has benefits of higher conversion rates, product uniformity & less energy losses. CSTR stands for Continuously Stirred Tank Reactor. PFR stands for Plug Flow Reactor.

A drain plug is just a bolt used to plug a hole preventing liquid flow from that hole.
