Abstract:
1. A method for analyzing a fluid residual product in a cleaning system, the fluid residual product consisting of a rinsing or a cleaning solution and a product removed from equipment used in a manufacturing system for the product, with additional steps of determining the amount of said fluid residual product being delivered to one of at least two destinations, comprising the steps of (a) deaerating a flow of said fluid residual product, (b) thereafter continuously measuring a full flow (Q) of fluid residual product per short time unit (dt) at a predetermined location in the cleaning system, (c) continuously measuring per the same short time unit (dt) a magnitude (C) corresponding to the content(s) of product in the fluid residual product at said predetermined location in the cleaning system, (d) determining, based on said measurements, an amount of product (Q′) that flows through said predetermined location per the same short time unit (dt), where Q′=C*Q, (e) calculating the total amount (V (f) reporting said amount (V (g) calculating the volume (V′) of a piece of conduit between a flow meter and a boundary valve, (h) calculating time (t′) for the fluid residual product to flow from the flow meter to the boundary valve by the use of an iterative calculation starting at the time (t (i) calculating the time (t′ (j) calculating the time periods for delivery (t (k) determining the partial amount of the fluid residual product to each of said respective destinations, and (l) reporting said partial amount of fluid residual product to each of said respective destinations.
