Abstract
A process for concentrating and diluting a treatment substance to provide a diluted treatment for introduction to a wellbore is disclosed. In one embodiment, the process includes measuring a treatment fluid flow rate. The process also includes blending the treatment fluid with a treatment substance to produce a concentrated treatment fluid. The process further includes measuring a flow rate of the concentrated treatment fluid. Moreover, the process includes determining a difference between the treatment fluid flow rate and the flow rate of the concentrated treatment fluid. In addition, the process includes comparing the difference to a target difference. The process additionally includes adjusting the difference to be within a desired range of the target difference and diluting the concentrated treatment fluid to provide the diluted treatment fluid.
