Liquid Absorption

Liquid speciation is important for reliable process design and optimization of gas-liquid absorption process. Liquid-phase speciation methods are currently available, although they involve tedious and time-consuming laboratory work. Raman spectroscopy is well suited for in situ monitoring of aqueous chemical reactions. Here, we report on the development of a method for speciation of the CO2-NH3-H2O equilibrium using Raman spectroscopy and PLS-R modeling. The quantification methodology presented here offers a novel approach to provide rapid and reliable predictions of the carbon distribution of the CO2-NH3-H2O system, which may be used for process control and optimization. Validation of the reported speciation method which is based on independent, known, NH3-CO2-H2O solutions shows estimated prediction uncertainties for carbonate, bicarbonate, and carbamate of 6.45 mmol/kg H2O, 34.39 mmol/kg H2O, and 100.9 mmol/kg H2O, respectively.

AbstractRotating Polarization Coherent Anti-Stokes Raman Spectroscopy (RP-CARS) is a novel approach to CARS microscopy that takes advantage of polarizationdependent selection rules in order to gain information about molecule orientation anisotropy and direction within the optical point spread function. However, in the original implementation of this technique, the lockin amplifier-based acquisition was quite time demanding. Here we present a new software-based approach that permits a great speed-up in the RP-CARS images acquisition process.
