Batch treating, definition

A type of processing equipment in which the entire amount of material to be used is put into the mixer and mixed for a definite period, with multiple recirculation of material through the mixing zone, in contrast to what happens in a continuous mixer. After the mixing period the whole amount of material is removed from the mixer. In oil production or processing, the process in which emulsion is collected in a tank and then broken in a batch. This process is used as opposed to continuous or flow-line treating of emulsions. 

A simple review [6] of the definition of a distribution coefficient (equation 5) enables the calculation of the column capacity for a cation from equilibrium batch tests, provided that the concentration of the ion being scavenged by the zeolite is low in the solution being treated. This is particularly useful when removal of radioisotopes from aqueous nuclear waste is the intended use [30]. 

In batch distillation (whether of the simple or countercurrent type) a definite charge is put into the still and treated. A distinction should be made between fractional and unfractionated distillation. In the latter, the whole distillate is collected in one lot, and the initial material is thus separated into two fractions the distillate and... 

Type I. For parallel reactions with separate reactants, the analysis is easily handled, since the two steps are independent of each other. Indeed, the inclusion of Type 1 as a nearly complex scheme is not really necessary for the homogeneous batch reactions at constant volume treated here, since the yield and selectivity definitions are redundant in this case with rate and conversion. The system is important in heterogeneous systems, however, so we introduce it for later reference. For first-order, irreversible reactions ... 

It is clear from the above classification that batch processes are usually of the isolated or closed type, whereas the continuous processes are usually of the open type. As can be seen from the above definitions, the system theory is very abstract and, in general, it treats any system regardless of whether a mathematical model for this system can be built or not mathematical modeling, on the other hand, is less abstract and more applied than the system concept.
