Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) were used to qualitatively distinguish ammonium bicarbonate from ammonium carbonate and ammonium carbamate, while CHN elemental analysis and near-infrared (NIR) spectroscopy were used to quantify ammonium bicarbonate based on multivariate regression methods as reported in [9].
If a leak were to occur on the high C[O.sub.2] pressure side of the cascade condenser, the C[O.sub.2] would leak into the N[H.sub.3] and chemically react to form ammonium carbamate ([H.sub.2]NC[O.sub.2]N[H.sub.4]), which is corrosive to steel and appears as a white powder precipitate.
