Batch-process control

Actual development of intelligent batch process control systems, for lab, pilot plant, and plant, based on better process understanding and better instruments. [Pg.472]

Products in Group 3 seem to us to represent the future of practical batch process control. In such systems, modern workstations perform the single-user functions (e.g control system design, set-up, and maintenance operator interface data collection historical reporting) for which they were designed, while powerful multitasking controllers perform actual control. As computer hardware and software standards continue to evolve toward distributed networks of processors optimized for specific kinds of tasks, such systems will, we feel, proliferate rapidly. [Pg.474]

The batch process control system we ve purchased provides only a starting point for our process research lab we must also identify and test a comprehensive set of controlled devices and real-time process instruments for chemists and engineers to use as building blocks for real feedback control systems. The technologies we are evaluating for characterization of polymer batches at all process stages include ... [Pg.475]

Medicinal products and bulk pharmaceutical chemicals are produced mainly in batch processes. Controlling these products and chemicals at the end of their manufacturing processes is not in line with the general principle of quality assurance, which is that quality should be built into the product. It is then necessary to ensure that appropriate good manufacturing practices are adhered to throughout the manufacture of both bulk pharmaceutical chemicals (active ingredients as well as excipients) and medicinal products. [Pg.513]

Development of automated batch process control systems has lagged behind that of continuous process control. Flexible factory scale commercial systems have only begun to appear in the last five years (1-4). Increases in the performance/price ratio of small computers are now making automation of laboratory scale batch processes more practical. [Pg.179]

Ghosh [2] also lists the requirements for batch process controllers. Batch control methods must include the abilities to ... [Pg.444]

There are a number of tools available to the process engineer for designing a preset process cycle for regulating secondary variables such as temperature and pressure and for supervisory control of the process cycle based on inferred composite properties. Many of these have been tested in a variety of applications. None of these tools is capable of handling all of the tasks of a batch process controller but they can be combined, and the resulting systems have potential far beyond that of any one tool by itself. [Pg.467]
