Abstract
The present disclosure provides improved systems and methods for the blending of active agents into process fluids.
Claims31
A continuous system, comprising:
- a mixing tank,
- the mixing tank being configured to receive a carrier from an input source of a carrier and being configured to receive a chemical agent from at least one input source of a chemical agent;
- a sensor in fluid communication with a recirculation line capable of fluid communication with the mixing tank, the recirculation line configured to receive process fluid from the mixing tank, and the sensor being configured to measure a level of the chemical agent in the recirculation line;
- the system being configured to give rise to a process fluid in the recirculation line that comprises the carrier and the chemical agent, the process fluid being characterized as being substantially homogeneous;
- the system being configured to release to a use location downstream from the mixing tank (a) process fluid from at least the mixing tank, (b) process fluid from at least the recirculation line, or (c) process fluid from at least both the mixing tank and recirculation line;
- a mixer disposed in fluid communication with the mixing tank and connected to a mixing tank input stream, wherein the mixer is configured to receive the carrier and the chemical agent that have not yet reached the mixing tank, to mix the carrier and the chemical agent, and to communicate the mixed carrier and chemical agent to the mixing tank through the mixing tank input stream;
- an analysis recycle stream connected to the sensor and configured to receive the process fluid from the recirculation line and configured to provide the process fluid to the mixing tank;
- a pump configured to transport contents of the mixing tank to the recirculation line for receipt by the mixing tank through the analysis recycle stream;
- and
- a controller, in operative communication with the sensor and the pump, the controller configured to:
- modulate a flow to the mixing tank from the input source of the carrier, from the input source of the chemical agent, or any combination thereof;
- and
- operate the pump to transport contents of the mixing tank to the recirculation line for receipt by the mixing tank through the analysis recycle stream.

A method, comprising
- mixing, in a mixer, a carrier and a chemical agent, wherein the chemical agent comprises cetylpyridinium chloride, quaternary ammonium, chloride, chlorine dioxide, bromide, potassium bromate, hydroxide, halogen, organic peroxide, inorganic peroxide, nitrogen dioxide, acid, chlorate, hypochlorite, or any combination thereof;
- in a mixing tank, mixing a combined flow of the carrier and the chemical agent so as to give rise to a process fluid that is characterized as substantially homogeneous, wherein the mixer is configured to receive the carrier and the chemical agent that have not yet reached the mixing tank;
- transporting at least some of the process fluid to a recirculation line in fluid communication with the mixing tank;
- determining a level of the chemical agent in the process fluid in the recirculation line;
- transporting at least some of the process fluid of the recirculation line to the mixing tank;
- optionally changing the concentration of the chemical agent in the process fluid based at least in part on the level of the chemical agent in the recirculation line;
- and
- communicating at least some of the process fluid to a use location.
5 more elements
A method, comprising:
- mixing, in a mixer, a carrier and a chemical agent;
- introducing to the mixing tank an amount of a combined flow of the carrier and the chemical agent so as to give rise to a process fluid, wherein the mixer is configured to receive through the carrier and the chemical agent that have not yet reached the mixing tank;
- transporting at least some of the process fluid to a recirculation line in fluid communication with the mixing tank;
- measuring a level of the chemical agent in the process fluid of the recirculation line;
- transporting at least some of the process fluid of the recirculation line to the mixing tank;
- based at least in part on the level of the chemical agent in the fluid of the recirculation line, transporting at least some of the process fluid in of the recirculating line to a use location;
- and
- exposing a sample at the use location to the process fluid.
