Types of Reactors - Chemical Engineering World

Chemical reactors are designed in such a way to increase the net present value for a given reaction and it is done by ensuring highest efficiency to output the desired product. Types of Reactors. Batch Reactor; Continuous Stirred Tank Reactor (C.S.T.R) Plug Flow Reactor (P.F.R) Semi-Batch Reactor; 1. Batch Reactor

Batch Reactor - an overview | ScienceDirect Topics

A semi-batch reactor will have some addition and/or removal during the course of the reaction; a T-flask is a semi-batch reactor if media is changed between passages. Batch reactors can be operated as static or mixed; a T-flask is static ( Fig. 3.1 ) and a stirrer flask, such as a Techne® Flask ( Fig. 3.2 ) is mixed.

ISOTHERMAL SEMI-BATCH REACTOR APPARATUS at Rs .

An isothermal semi-batch reactor is a semi-closed system with one input stream. It is operated under conditions like Isothermal (Temperature of Reaction Mass remains constant) and perfectly mixed (composition of reaction mixture is uniform throughout). This set-up is used to study a non-catalytic homogeneous reaction under isothermal condition.

Chemical Reactors: Semi-Batch Reactors

2006-4-23 · A semi-continuous reactor is a reactor for a multiphase reaction in which one phase flows continuously through a vessel containing a batch of another phase. The operation is thus unsteady-state with respect to the batch phase, and may be steady-state or unsteady-state with respect to the flowing phase, as in a fixed-bed catalytic reactor or a fixed bed gas-solid reactor respectively.
