Batch - Visual Encyclopedia of Chemical Engineering

Batch reactors contain ports for injecting reactants and removing products, and can be outfitted with a heat exchanger or a stirring system. While batch reactors are generally of constant volume, some are designed to maintain a constant pressure by varying the reactor volume. The picture below shows the top of a batch reactor.

Fundamentals of Chemical Reactor Theory1

Continuous-Stirred Tank Reactor A CSTR differs from a batch only in the fact that it is not closed. Thus, the mass flows in and out of the reactor in eq. [6] will not cancel: () 0in out V dm Qc c rdV dt . [14] The mass balance in [14] equals to 0 thanks to the steady state hypothesis (=no accumulation). Solving,

Continuous Stirred Tank Reactors - Visual Encyclopedia of .

Continuous stirred-tank reactors (CSTRs) are open systems, where material is free to enter or exit the system, that operate on a steady-state basis, where the conditions in the reactor don't change with time. Reactants are continuously introduced into the reactor, while products are continuously removed.

Chemical Reactors > Design of The Reactors > The .

Batch reactors are used for most of the reactions carried out in a laboratory. The reactants are placed in a test-tube, flask or beaker. They are mixed together, often heated for the reaction to take place and are then cooled. The products are poured out and, if necessary, purified. . Continuous stirred tank reactors, CSTR.

Corrosionpedia - What is a Batch Reactor? - Definition .

A batch reactor is the simplest type of reactor vessels use for chemical or industrial processes. A typical batch reactor consists of a tank where chemical reactions occur. These tanks also have an agitator and an internal heating or cooling system. Tank sizes range from one liter to 15,000 liters.

The stirred tank batch reactor is still the most widely used reactor type both in the laboratory and industry. A batch reactor is one in which a feed material is treated as a whole for a fixed period of time. Batch reactors may be preferred for small-scale production of high priced products, particularly if many sequential operations are carried out to obtain high product yields.
