A method and apparatus for diffusing or reducing gas into a liquid is described. This invention covers several different methods for infusing or reducing gas into a liquid with a feedback loop that monitors specific parameters of the process and can vary controls to achieve a targeted value or keep within a range of values. The parameter of interest is the ORP (Oxidative Reduction Potential) and one way to determine that value is using an ORP sensor to directly measure it at various points in the process such as on the untreated incoming process fluid, right after infusing the reducing gas, or later in the process such as where the fluid is discharged back into the original tank in the case of a recirculating system or when it is discharged to the next phase of the treatment train.

The disclosure features a system that includes a plurality of material tanks, each of which includes at least one material for forming a chemical composition and includes a first recirculation loop; at least one mixing tank in which the materials from the material tanks are mixed to form a chemical composition, the mixing tank including a second recirculation loop; and at least one holding tank configured to continuously receive the chemical composition from the mixing tank, the holding tank including a third recirculation loop. The system may further include a plurality of fluid flow controller units and be configured to form material and chemical composition flows in an in-process steady state.

A method of determining a dry proppant concentration in a fracturing fluid includes combining a wet proppant with a carrier fluid in a mixer to form the fracturing fluid. The dry proppant concentration of the fracturing fluid leaving the mixer is determined using a moisture content of the wet proppant entering the mixer, wherein use of the moisture content prevents overestimation of the dry proppant concentration. The method can be preformed using a system for injecting fracturing fluid into a borehole, the fracturing fluid including a carrier fluid mixed with a wet proppant including a dry proppant dampened with a dampening liquid. The system includes a mixer operable to receive and mix the carrier fluid and the wet proppant to form the fracturing fluid, a frac pump operable to inject the fracturing fluid into the borehole, and a control system comprising a processor operable to receive a moisture content of the wet proppant before being mixed with the carrier fluid and programmed to determine a dry proppant concentration of the fracturing fluid formed in the mixer using a moisture content of the wet proppant, wherein use of the moisture content prevents overestimation of the dry proppant concentration.
