Although not
BATCH CHEMICAL REACTOR This example problem is based on an existing industrial batch reaction system. It illustrates a batch reactor where a quinone-type organic compound is hydro- genated to a hydroquinone. The reaction product is an intermediate for a pharmaceutical. Reactors require a detailed hazard analysis before the proper Process
Effectively contacting materials is crucial for operations ranging from solids suspension to gas dispersion and from reacting raw materials to compounding finished ingredients. The wide variety of mixer types — dynamic and static, as well as in-tank and in-line — and the design options for the mixers and vessels can make selecting the right unit tough. And troubleshooting an existing unit .
A batch reactor has neither inflow nor outflow of reactants or products while the reaction is being carried out: F j 0 = F j = 0. The resulting general mole balance on species j is. If the reaction mixture is perfectly mixed (Figure 1-5(b)) so that there is no variation in the rate of reaction throughout the reactor volume, we can take r j out of the integral, integrate, and write the mole .

The center of any chemical process is the reactor, where chemical reactions are carried out to transform feeds into products. Reactor design is a vital step in the overall design of a process. It is important to ensure that the equipment specified will be capable of achieving the desired yields and selectivity. Ideal Reactors Batch Reactors
We have examined a number of conservation and rate equations that are applicable to all Chemical and Biological Engineering processes. However, it is useful to examine some processes specifically biological in nature. We could cover biological heat transfer, biological mass transfer, biological reactors, etc.
Chemical reactors have several components, such as a jacket that can increase or reduce the temperature as per the reaction mass demand, internal coils that provide heat to reaction mass when needed, an external heat exchanger that is used for circulation purpose, the cooling effect that may help while transferring reaction mass from one reactor to other, an agitator that mixes the reaction .

Semi-batch reactors occupy a middle ground between batch and continuous reactors. They are open systems like CSTRs and run on an unsteady-state basis like batch reactors. They usually consist of a single stirred tank, similar to a batch reactor. The half-pipe coil jacketed reactor shown below can be used in semi-batch operations.
