Polymerization Plug Flow Reactors for Viscous Processing .

Plug Flow: In addition to excellent radial mixing, continuous reactors require plug flow conditions. Plug flow conditions means that all the material processed through the reactor must have the same residence time so that the chemicals exiting the reactor have witnessed the same reaction conditions of reactive species contact-time aging-temperature history.

How to Make Water From Hydrogen and Oxygen

Mix the two gases together, add a spark or sufficient heat to provide the activation energy to start the reaction, and presto—instant water. Merely mixing the two gases at room temperature, however, won't do anything, like hydrogen and oxygen molecules in the air don't spontaneously form water.

Many chemical reactions are non-reversible changes. This means they are permanent changes that cannot be undone. You cannot turn the new materials made back into the original materials again. Rusting is a non-reversible change. However, if rust is mixed with magnesium powder another chemical reaction occurs and iron can be extracted from the rust.
