US Patent:

7281840, Oct 16, 2007

Filed:

Jul 9, 2004

Appl. No.:

10/887705

Inventors:

Michael B. Simpson - Elgin TX, US
George V. Woodley - Reno NV, US
Gary R. Anderson - Austin TX, US

Assignee:

Tres-Ark, Inc. - Austin TX

International Classification:

B01F 15/02

US Classification:

366132, 366136, 3661521

Abstract:

There is disclosed a system and method of formulating a batch comprising at least two ingredients. The ingredients are admitted to a container to partially fill it. The quantities of the ingredient in the container are determined, and a ratio of a target quantity to the determined current quantity for at least one ingredient is calculated. The next quantity of that ingredient to be admitted to the admixture is calculated by multiplying the target quantity by the calculated ratio to determine a corrected quantity. The corrected quantity of the ingredient is admitted to the admixture, and a quantity of another ingredient is admitted to the admixture to adjust the proportion of ingredients to the target formulation. These steps may be repeated until the batch is completed.

International Classification:

G06F 19/00

US Classification:

702019000, 702022000

Abstract:

There is disclosed a system and method of formulating a batch comprising at least two ingredients. An embodiment is disclosed wherein a feedforward algorithm can be used to control the target blend. Subsequently a feedback closed loop control loop algorithm is provided for a multivariant blend. Use of this approach allows for a continuously autoreplenished and controlled blend. Another enhancement disclosed is the ability to control via feedforward and feedback algorithms a fast responding control mode which allows for the elimination of a tank. This approach will allow for “one pass” blending with control. Feedback control can be provided via process indicators or through analytical or parametric methods. The controller implements an automated fault detection and correction system, thereby identifying necessary maintenance prior to failure. If failure does occur the signature recognition allows rapid analysis and correction thus maximizing tool availability.
