Abstract

Certain control functions in large scale industrial processes are accomplished through the use of a process simulator. This is a small replica of the main process or a simulator of a particular operation in the main process. The simulator operation conforms with the main process and provides a determination of the instantaneous value of a chosen operating parameter at any given point in time. Thus it is possible to effect calculation of needed data on the corresponding operating parameter in the main process at that same point in time. In this arrangement, it is possible to more readily measure a parameter in the simulator than in the main process, and to restrict use of intrinsic radiotracers to such simulator.

Control of Processes by Process Simulator Incorporating Radiotracers

Certain control functions in large scale industrial processes are accomplished through the use of a process simulator. This is a small replica of the main process or a simulator of a particular operation in the main process. The simulator operation conforms with the main process and provides a determination of the instantaneous value of a chosen operating parameter at any given point in time. Thus it is possible to effect calculation of needed data on the corresponding operating parameter in the main process at that same point in time. In this arrangement, it is possible to more readily measure a parameter in the simulator than in the main process, and to restrict use of intrinsic radiotracers to such simulator.

Certain control information for a particular process can thus be obtained and applied for the control of the main process even though the control information is not obtained as feedback directly from the process, but rather from the simulator which carries out the process on a substantially reduced scale. It is not necessary that the main process and that carried out by the simulator behave identically, but only that their behavior relationships be known. The control information is obtained through the use of intrinsic radiotracers. Dynamic control of a main process is under control of process simulator 7. This functions the same as the main process except that such simulator is consider...
