Abstract

The objectives of the study were explore the probable contribution of congeners and determine the effect of number of pressure cycles on the dusting of molecular sieves. The responses determined were change in bulk mass and the crushing strength of molecular sieves. the dehydration set-up used was the one fabricated by Olea 92012) and was retrofitted to simulate industrial adsorption and regeneration process. The specifications of the set-up were determined through preliminary runs. It was determined that methanol concentration, combined congener concentration (methanol, acetone and ethyl acetate with ratio 1:0.65:0.01 weight basis) and number of pressure cycles have significant effects on the change in bulk molecular sieve mass. There was no significant interaction between congener concentration and number of pressure cycles observed on the experiment. The projection of dusting was done for a 300-cycle start-up operation where it was observed that the highest dusting of 64.988 grams was at 0.75% v/v methanol concentration. On the other hand, it was determined that only the number of pressure cycles and significant effect on the crush strength of molecular sieves. There was no significant interaction between congener concentration and number of pressure cycles observed on the experiment.
