Systems and methods for monitoring chemical processes

摘要

A method of monitoring a fluid includes containing the fluid within a flow path, the fluid having a chemical reaction occurring therein. At least one integrated computational element is optically interacted with the fluid, thereby generating optically interacted light. An output signal is then produced based on the optically interacted light that corresponds to a characteristic of the chemical reaction.

1. A method of monitoring a fluid, comprising:
containing the fluid in which a chemical reaction is occurring within a flow path; interacting an electromagnetic radiation source with the fluid to form a sample interacted light; separating a portion of the sample interacted light with a beam splitter; measuring the intensity of the separated portion of the sample interacted light with a first detector to form a compensating signal indicative of radiative deviations from the electromagnetic radiation source; optically interacting at least one integrated computational element with the fluid using the sample interacted light, thereby generating modified electromagnetic radiation, the integrated computational element comprising a plurality of layers of dielectric materials deposited on an optical substrate according to a characteristic of the chemical reaction; producing an output signal by measuring the modified electromagnetic radiation with a second detector coupled to the integrated computational element; receiving the output signal and the compensating signal with a signal processor communicably coupled to the first and second detectors; and determining the characteristic of the chemical reaction with the signal processor by comparing the output signal with the compensating signal, wherein the processor is programmed to adjust a flow of a treatment reagent being introduced into a flow path based on the determined characteristic of the chemical reaction in response to an out of range condition.
