I need help calculating the height of the adsorption bed in a fixed-bed adsorber
Thread Content
Who has any books or formulas for calculating the height of the adsorption bed in a fixed-bed adsorber? It’s urgent!
1. Penetration curve method 2. Hilov method t’=KZ, where t’ is the ideal penetration time, s; K is the adsorption layer protection constant, in s/m; Z is the height of the adsorption layer bed, in meters (the value to be determined)
The modified Hilov equation: t = t’ – t0 = KZ – t0 = K(Z – Z0). Here, t represents the actual penetration curve; s*t0 represents the loss in adsorption time, and s*Z0 represents the loss in the height of the adsorption bed. The values of m, t0, and Z0 can all be determined through experiments. Under certain conditions, a series of penetration curves corresponding to different bed heights are measured; by plotting a straight line graph of t versus Z, the slope of this line gives K, while the intercept gives t0. From this, Z0 can be calculated
