TI  - On-line determination of the molar ratio between methanol and isobutylene in 
      feedstock of a methyl tertiary butyl ether production plant using near-infrared 
      spectroscopy.
PG  - 96-101
AB  - The molar ratio between methanol and isobutylene (MRMI) is very important to the 
      operation of methyl tertiary butyl ether (MTBE) production units. A new on-line 
      near-infrared (NIR) analytical system was integrated for monitoring the MRMI in 
      real time and was successfully applied in a rubber plant. Calibration models for 
      methanol and isobutylene were established using partial least squares (PLS). The 
      sample temperature effect on the performance of the models is discussed. The MRMI 
      is calculated by methanol content and isobutylene content predicted by NIR. A 
      large benefit has been obtained by the user through controlling the operation of 
      the unit according to the monitoring of the MRMI of the feedstock in real time.
