Frictional temperature regulation of a fluid

A production method can include flowing a heterogeneous fluid mixture into contact with a homogenizing cutting tool, measuring a fluid mixture temperature so as to obtain a measured fluid mixture temperature, and determining a target fluid mixture temperature. The fluid mixture can be frictionally heated so as to obtain a heated and homogenized fluid mixture by driving the cutting tool at a rate based on (i) the target fluid mixture temperature and (ii) the measured fluid mixture temperature. The heated and homogenized fluid mixture can be flowed away from the cutting tool.

On-demand in-line-blending and supply of chemicals

This in-line active and reverse calculating mass balance blending system can maintain a chemical at desired control points, such as with respect to concentration, temperature, and/or pressure, while the output flow rate is changing dynamically to a point of use. A blending unit is configured to receive and blend at least two species and deliver a mixture at selected concentrations to points of use. A controller can be configured to determine a mass balance to maintain the concentrations in the mixture using information from metrology systems and a flow in an output to the at least one point of use. The controller also can be configured to maintain a concentrations in the mixture within a concentration range by controlling flow rates to the blending unit.
