We used FTIR to analyze the interaction between the alkanolamine solution and carbon dioxide, and to evaluate the effect of the zinc–metal complex on the regeneration efficiency.

The ATR method makes it possible to perform rapidly assays without sample preparation even with strong absorption of IR radiation by water. For determination of MDEA and piperazine an aqueous amine sample is dosed out directly onto prism surface of the ATR unit.

Jan 1, 2011 · In this work speciation data of MDEA-H 2 O-CO 2 have been determined experimentally with a Fourier Transform Infra-Red spectrometer (FTIR) at ambient temperature. After several calibration lines were prepared, the speciation of this system was determined online in …

Nov 1, 2023 · Additionally, Fig. 4 displays the FTIR spectra of the carbonated solution with MDEA, demonstrating its changes over carbonation time. The results show that the peak at around 1445 cm −1 for pure MDEA represents the bending of N-H bonds.

Aug 26, 2019 · A Fourier transform infrared (FTIR) spectroscopy method was developed to identify and quantify various components in an amine-based combined acid gas and water removal process. In this work, an attenuated total reflectance (ATR) probe was used.

Apr 16, 2004 · VLE measurements of low carbon dioxide and hydrogen sulfide concentrations in aqueous mixtures of methyldiethanolamine (MDEA) are reported using the new FTIR technique.

O2-loaded MDEA blends to predict the weight percentages of MDEA, H2O, CO2, and MEG or TEG to test the performance spectrum. The results confirmed that FTIR could be used as a simpler, quicker and reliable tool to identify and qu

Aug 26, 2019 · A Fourier transform infrared (FTIR) spectroscopy method was developed to identify and quantify various components in an amine-based combined acid gas and water removal process.

Figure 4 shows the FTIR spectra of lean MDEA and PAAM sepiolite clay composite hydrogel before and after adsorption.
