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.

Definition of recycle and purge stream?
Recycle stream is a process in which a portion of the output stream is returned to the input stream for further processing. Purge stream is the removal of a portion of the output stream to prevent accumulation of impurities or by-products in the system.
Basic operation of plug flow reactor?
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.
What is a plug flow reactor and what are its concentration characteristics?
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.
Where can I recycle Soda Stream bottles?
You can recycle Soda Stream bottles at many local recycling centers or drop-off locations that accept plastic bottles. Check with your city or waste management department for specific recycling options in your area.
What is the difference between a continental jet stream and a polar jet stream?
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
What is a dangerous condition caused by the overheating of the nuclear core of the reactor?
Overheating of the reactor fuel rods could damage the zircaloy sheaths and enable gaseous fission products to enter the reactor coolant stream. This alone would not be dangerous, but if a loss of coolant had caused the overheating then this could release activity into the secondary containment. What would follow from this depends on the individual design of the plant.
The main difference between stream pools and ponds is that stream pools?
The main difference between stream pools and ponds is that stream pools are dynamic water bodies formed in the current of a flowing stream, where water collects and slows down, often creating deeper areas. In contrast, ponds are typically still water bodies that can be isolated from flowing water systems. Stream pools are influenced by the flow of the stream, while ponds are more stable and can support distinct ecosystems.
What is the difference between a perennial stream and an intermittent stream?
Perennial is a stream or river that has a continuous loop of a flow in parts of a stream bed all year round during years of normal rainfall. A intermittent is a stream or river which carries water in a considerable portion of the time, but ceases to flow occasionally or seasonally because bed seepage and evaporation/transpiration exceed the available water supply. That is a summarized form of what each stream are. In conclusion, the difference is the way the stream flows. Perennial is a circular stream that is steady all year long, while a intermittent stream is at a specific timing.
What is difference between a stream and river?
The difference between a river and a stream is the name applied to it by local residents, and relative size. In the same region, something called a river is usually larger than something called a stream. However, something that is called a river in one place could be the same size as something called a stream in another place.
What is the difference between stream deposition and changing running water velocity?
Speeds up
What is the difference between binary and character?
binary stream reads data(8-bits) irrespective of encoding, character stream reads two bytes as character and convert into locale stream using unicode standard. binary stream better for socket reading and character stream is better for client input reading
What is the difference between us invert level and ds invert level?
US = Up Stream invert level DS= Down Stream invert level If detailed on a manhole, the difference being the gradient of pipe in chamber from one end to the other.
