| Abstract: | The molar ratio between methanol and isobutylene is one of the most important control parameters in MTBE production plant. It is summarized that the analysis technique for determining the molar ratio between methanol and isobutylene,including gas chromatography,on-line gas chromatography, and soft-sensing technique. The principle, characteristics of those methods are described in detail. Moreover, the on-line near infrared spectroscopy to determine the parameters for the first time is introduced, and some key experimental results are displayed. The technical proposal is hopeful to become an excellent alternative method for determining the molar ratio between methanol and isobutylene. |
