Abstract

The syngas composition change during the measurement process was analyzed using a detailed gas phase reaction mechanism. Results showed that the measurement error induced by the temperature and pressure change in the measurement process cannot be ignored. Based on the results, suggestions were proposed for syngas concentration measurement and temperature measurement.

Tab.1 Tampa IGCC power plant syngas composition (mole fraction)

Fig.1 Syngas composition change during the cool-down process as temperature linearly decreased to 373.15 K from 1588.15 Kin 50 s

Fig.2 Measurement error due to the cool-down process (temperature gradually decrease to 373.15 K in 50 s)

Fig.3 Relative error under different cooling time

Fig.4 Use of the Laval nozzle to cool the syngas first ant then use other method to cool the syngas down (The temperature is cooled down to 772.2, and pressure is dropped to 1 atm in 0.01 s, which is a rough calculation result)
