In caffeine, breakthrough times, corresponding to C/C0 = 0.02 were found to be 19.1, 47.6 and 48.5 h for the columns operating with bed weights of 0.6, 0.8 and 1.0 g, respectively.
Formation of gas flow pathways, either caused by capillary pressure or mechanical stress, can result in gas breakthrough, the corresponding pressure of which is determined according to the evolution of gas flow rate and can be used as the working gas pressure for avoiding significant gas loss in the gas-tight working structures in pneumatic caisson method and compressed air tunneling technique.
The sorption capacity of the ETS-4 in the column in two consecutive cycles remained constant (33.6 and 33.3 mg g−1, respectively); however due to certain difficulties encountered during ETS-4 packaging and operation mode, breakthrough curves corresponding to these cycles showed dissimilar patterns.
Uncertainty bounds derived by this MCMC method simultaneously capture the observed Br− and Cl− breakthrough curves and corresponding drainage volumes.
According to the above experiments, the corresponding breakthrough volumes of alkaloids on H-103 resin column of diameter-to-height ratio 1/10 were 88 BV at the concentrations of 0.2 mg/mL, at the flow rate of 4.0 BV/h).
Up until now, however, this has not led to corresponding breakthroughs in our ability to design novel ligands for protein targets of interest.
A simple theoretical model is used to calculate dimensionless breakthrough curves and the corresponding temperature profiles for a non-isothermal adsorption column, operating under constant pattern conditions.
It is shown that breakthrough curves are sharper than corresponding internal breakthrough curves for beds of any length, with the difference being even more pronounced in shallow beds than in deep beds.
The critical flow rates, Qc−10, corresponding to immediate breakthrough, ranged from 70 to 290 mL/min and varied directly with the affinity of the vapor for the adsorbent.
Based on some solid phase analysis data and kinetic batch experimental results, we hypothesized three two-site sorption models in the LEHGC reactive transport model to fit the breakthrough curves (BTCs) from the corresponding column experiments.
The experimental results reveal that loading pattern was not found to have any significant influence on the flexural tensile strength of the soil; however, a considerable influence on the displacement corresponding to gas breakthrough was noticed mainly due to the variation in the cracking pattern.
