Process control engineering

Remark 6. Note that in order to achieve a good control the loop 3 must be faster than the loop 2. The values of the PI controllers can be obtained from the basic methods of engineering process control. As an example, the following data have been obtained for the reactor number 4 in Table 2 ... 

It is the convention in chemical engineering process control to use minutes as the normal unit of time for a time constant. This convention is followed in this text. 

Chapter 17 deals briefly with the engineering process control, which primarily involves measurement of a product property and comparison to a desired value. The process operation can be thus immediately adjusted to reduce deviation from the specifications. This feedback procedure can be used to adjust the process whenever the product deviates from the set point and can be used to change operating points and to reject the effect of outside disturbances. 

Engineering process control is not generally the same as quality control or statistical process control engineering control is intended to continuously reject and attenuate errors which enter while the process operates, while most statistical control techniques seek to identify sources of error so that they may be eliminated by subsequent process or operation revisions. At times the two approaches are in conflict, for by correcting or compensating for a disturbance an engineering control system may distort the statistical parameters used in quality control analysis. 

There are many factors that are important in making plastic products the success it has worldwide. One of these factors involves the use of the availability of different fabricating processes. All processes fit into an overall scheme that requires interaction and proper control of operations based on material requirements. Thus fabricating is an important part of the overall project to produce acceptable plastic products. It highlights the flow pattern for the fabricator (manufacturer) to be successful and profitable. Recognize that first to market with a new product captures 80% of market share. Factors such as good engineering, process control, etc. are very important but only represent...
