Flow reaction
WebFlow chemistry also called continuous flow chemistry or plug flow chemistry is used to describe a range of chemical reactions that occur in a continuously flowing stream as contrasted to classic static batch reactor systems.What the two have in common is the “reaction time”. The chemical industry has used flow chemistry systems for decades … Webwhich, again, is the characteristic equation of the plug flow reactor. Considering a first-order reaction, the concentration equation will be 0 cc e kt. [22] Segregated Flow Analysis The non-ideality of industrial and natural processes lead engineers to develop corrections to the ideal models, in order to use them with less restrictions.
