Abstract: Disclosed herein are processes, apparatuses, and systems for monitoring and/or controlling caustic concentrations in caustic scrubbers. In various aspects, the processes, apparatuses, and systems comprise a real-time online method for measuring the concentration of caustic in process scrubbers wherein a probe is coupled to a spectrometer; collecting absorption data with wavelength range from about 1000 to about 2000 nm. In a further aspect, this technique tracks the use and recharge of caustic in process scrubbers. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
