• In each batch step, there is one chemical reaction of the type ν1A+ν2B ν3C +ν4D (1) • Most batch chemical reactors are operated at constant temperature and, if semi-batch, at constant feed rate of the reactant(s). Theoperating temperature and feed rate are determined heuristically, typically by doing a few laboratory experiments.

Semi-batch reactor. A semi-batch reactor is operated with both continuous and batch inputs and outputs. A fermentor, for example, is loaded with a batch, which constantly produces carbon dioxide, which has to be removed continuously. Analogously, driving a reaction of gas with a liquid is usually difficult, since the gas bubbles off.

Reactors for Biodiesel Production – Farm Energy

The main characteristic of a batch reactor is that it starts with unreacted material, causes it to react, and then at a later time ends up with reacted material. That is, a batch reactor contains different types of material depending on which time one happens to look at it. Batch reactors are generally used in small biodiesel production plants.

By the simple mapping of the semi-batch recipe to the tubular reactor and lumping of the feed amounts, the semi-batch production cannot be transferred to a continuous tubular reactor for a most reaction systems. This approach is only suitable for reaction systems where both monomers have nearly the same kinetic behaviour.
