Method and system for multi-zone modeling to identify the material properties in the storage tank

摘要

PROBLEM TO BE SOLVED: To provide a batch process control system using a storage tank without a mixer, in which properties of the storage tank pump out feedstock are accurately modeled, thereby enabling more accurately control the quality of a process.;SOLUTION: This model does not require the measurement of input or pump out flow quantity and does not assume perfect blending. The developed model may assume that feedstock input into a storage tank may remain layered with some mixing due to continuous convection, turbulence during loading, or other factors. The model may include a projection of the properties describing a storage tank layer of material input into the model. For each new load of storage tank input feedstock, model zones may be shifted and the original zone from which the feedstock is drawn may be updated with the properties from the new load of feedstock.;COPYRIGHT: (C)2012,JPO&INPIT
