Batch Plant - an overview ScienceDirect Topics

The batch plant consists of 5 processing units, including one mixing tank, two reactors (one large and one small), one separation unit and one packing unit. Among the five units, we model the dynamics of the two reactors. The process diagram is displayed in Figure 2.The model and solution statistics are listed in Table 1.By using the integrated optimization approach, a

Batch Process - an overview ScienceDirect Topics

In a batch process, the output of the process appears in quantities of materials or lots. A batch process has a beginning and an end. Batch processes are neither continuous nor discrete, but have the characteristics of both. Batch process is usually performed over and over. The product of a batch process is called a batch.

Batch Culture - an overview ScienceDirect Topics

A batch culture can be characterized by the specific growth rate µ (h−1) and population doubling time (PDT). The specific growth rate is defined as follows: [1] μ = 1 X d X d t. where X is the VCD and t the time. Integration of eqn [1] yields an expression for the specific growth rate: [2] μ = ln ( X 2 / X 1) t 2 − t 1.

Batch Processing - an overview ScienceDirect Topics

1974-1-30  Most manual techniques employ batch processing, due to the convenience of performing a single operation many times. The total time taken to process a group of samples is equal to the sum of the times for each unit operation in the analysis multiplied by the number of samples in the batch. There are a number of disadvantages of batch processing.
