ALKYLAROMATIC DEHYDROGENATION SYSTEM AND METHOD FOR MONITORING AND CONTROLLING THE SYSTEM

摘要

An alkylaromatic dehydrogenation system is described. In addition, a method is described for monitoring an alkylaromatic dehydrogenation process comprising: drawing a sample from the process at a first sample point; passing the sample through an analyzer; and measuring the amount of at least one component present in the sample wherein the sample is at least partially uncondensed. An apparatus is also described for monitoring an ethylbenzene dehydrogenation process comprising a plurality of sample lines that are heat-traced sufficiently to inhibit condensation in the sample lines; and a Fourier Transform Infrared Spectrometer comprising two sample cells wherein the ratio of the length of a first sample cell to the length of the second sample cell is from about 1:1000 to about 1:1.
