(583c) A New Technique to Measure Multicomponent Adsorption Equilibrium: Integral Mass Balance (IMB)
AIChE Annual Meeting
Wednesday, November 13, 2019 - 4:10pm to 4:30pm
A new flow-through system is developed and tested to quickly measure binary adsorption equilibrium data at any desired T,P and yi. More importantly the experiments are very fast in the order of an hour per data point, compared to one point per day with systems/techniques with comparable accuracy. Unlike other similar systems based on breakthrough integration, the incorporation of an electronic balance eliminates the need to measure the outlet flowrate. Hence, the technique does not have an exit flowmeter which is usually the source for large uncertainties in measured partial amount adsorbed. The composition of the outlet gas is measured as usual in all chromatographic techniques. A quadrupole-Mass Spectrometer is used at outlet to closely monitor composition over time.
In this presentation, we will explain the concept, show the experimental system, explain data collection details, and examine the limitations of the approach. We will also show the test results comparing new measurements on O2/N2 mixtures in 5A-zeolite to those published by two different labs.
