Calibration techniques for FTIR process monitoring
Abstract
FT-IR process analyzers have been successfully installed on hundreds of processes around the world. Often streams analyzed are very complex multicomponent systems. Easy applications don't tend to be solved by FT-IR, easy applications get solved by less expensive technology. But the speed and low maintenance offered by on-line FT-IR analyzers attracts the attention of process people looking for a better way to control their plant. This paper describes applications in specialty chemicals, polymer production, and refinery production which demonstrate the range of techniques used to appropriately calibrate the on-line analyzer. Calibration transfer issues from lab to on-line analyses are discussed.
