SYSTEM FOR REMOVING CHEMICALS FROM A WORKING FLUID, AND METHODS RELATED TO THE SAME

摘要

A method for removing an unwanted chemical from a working fluid of a system includes: 1) pumping into a tank a working fluid that includes an unwanted, first chemical; 2) injecting into the tank a second chemical in an amount that provides or substantially provides a stoichiometric ratio relative to the amount of the unwanted, first chemical in the working fluid; 3) mixing the second chemical with the working fluid in a first portion of the tank to generate a molecule that precipitates out of the working fluid and that includes the unwanted, first chemical; 4) holding the working fluid in a second portion of the tank to separate the molecule from the working fluid; and 5) ejecting the working fluid from the second portion. The flow rate of the working fluid and the size of the first and second portions of the separation tank are coordinated to make the working fluid take at least 4 minutes to flow through the tank.

1. A method for removing an unwanted chemical from water, the method comprising:
pumping the water into a tank having a vertically oriented longitudinal axis, the water including an unwanted, first chemical; injecting a second chemical into the tank through a tube extending downward along the longitudinal axis at an adjustable location along the longitudinal axis, the second chemical being injected in an amount that provides or substantially provides a stoichiometric ratio relative to the amount of the unwanted, first chemical in the water; mixing the second chemical with the water in a first portion of the tank to generate a molecule that precipitates out of the water and that includes the unwanted, first chemical, the mixing being further promoted by varying a location of entry of the second chemical into the tank relative to a location at which the water enters into the tank; holding the water in a second portion of the tank to separate the molecule from the working fluid; and ejecting the water from the second portion.
