Process monitoring/control technologies

Technological advancements in process monitoring, control, and industrial automation over the past decades have contributed greatly to improve the productivity of virtually all manufacturing industries throughout the world. 

The second area, the implementation of a modem process monitoring and control system, is the most dramatic current appHcation of CAD/CAM technology to the chemical process industry. The state of the art is the use of computer graphics to display the process flow diagram for sections of the process, current operating conditions, and controUer-set points. The process operator can interact directly with the control algorithms through the... 

The first demonstration of solid state fluorescence of API dates back to 1961, while its in-line use for final drug product manufacturing was not demonstrated until recently." While in its infancy as a process analytical technology for real-time monitoring and product parametric real-time release, the applications identified and in some instances demonstrated include (i) blend endpoint API content nniformity detection " (ii) segregation monitoring or API content at various process critical control points and (iii) at-line tablet content uniformity determination. The fundamentals of solid-state luminescence spectroscopy for pharmaceutical solids has been covered by Brittain."...

The first apphcations of MAP that were disclosed pubhcly dealt with the extraction of essential oils from plant products [8], although the patented technology apphes to the extraction of a variety of chemical substances from a wide range of matrices such as water, soils, animal and plant tissues, as well as a variety of man-made products [1-6]. The fields of apphcation are also very diversified and include environmental, agricultural, food, biomedical, pharmaceutical, consumer products, and process monitoring and control. 

The next major advancements in MOCVD control system technology are likely to be in the area of feedback control. First and foremost is the incorporation of real time in-situ process monitors that directly provide feedback into the ongoing deposition process. Second, the development of software which converts a user defined structure to the run parameters for each layer of the structure however, this development appears to be several years away.
