Abstract: Liquid blending systems and methods of blending liquids are provided. In particular, systems and methods for compensating binary inlet buffers during inline buffer dilution are provided. The systems and methods can provide blends of diluent, a first buffer concentrate containing a majority of a tempering component, and a second buffer concentrate containing a minority of a tempering component. The flow of the first buffer concentrate can be adjusted based upon the total amount of the tempering component being added to the blend through the first and second buffer concentrates.

Abstract: An accurate blending system for blending first and second liquid components includes a first feed adapted to communicate with a supply of the first component and a second feed adapted to communicate with a supply of the second component. A shear blender is in communication with the first and second feeds. A first sensor is in communication with an outlet of the shear blender. A controller is in communication with the first sensor so that a first characteristic of a solution exiting the shear blender can be detected. The controller is also in communication with the second feed so that delivery of the second component to the shear blender can be controlled based upon the detected first characteristic.

Abstract: An accurate blending system for blending a feed liquid and first and second adjusting liquids includes a first feed means adapted to communicate with a supply of feed liquid, a second feed means adapted to communicate with a supply of the first adjusting liquid and a third feed means adapted to communicate with a supply of the second adjusting liquid. The first, second and third feed means may be pumps, valves or combinations thereof. A mixing device is in communication with the first, second and third feed means. First and second sensors are in communication with the mixing device. A controller communicates with the first and second sensors so that first and second characteristics of the solution in the mixing device can be detected. The controller also communicates with the first and second feed means so that delivery of first and second adjusting liquid to the mixing device can be controlled based upon the detected first and second characteristics of the solution in the mixing device.
