Patent ID: 7344297

Claim:
A method of operating a chemical blending system, comprising: a) mixing at least a first chemical stream with a second chemical stream in a blender system, said blender system comprising a mixing zone in a conduit system and in a real time controlled manner forming a first solution, wherein the first chemical stream and the second chemical stream are continuously introduced into the mixing zone; b) monitoring the first solution, wherein the monitoring results in a first solution output signal which is sent to a centralized monitoring system; c) adjusting a flowrate of the first chemical stream and a flowrate of the second chemical stream to maintain a predetermined formulation of the first solution; d) introducing the first solution into a first tank system, wherein said first tank system is connected to a chemical distribution system, and wherein the first tank system further comprises at least a first tank and a second tank; e) delivering a second solution having a predetermined formulation from the first tank system to the chemical distribution system; f) monitoring the second solution, wherein the monitoring results in a second solution output signal which is sent to the centralized monitoring system; and g) circulating solution out of the first tank system and back to the first tank system while adjusting the flowrate of the first chemical stream and the flowrate of the second chemical stream in order to maintain the predetermined formulation of the second solution.
