Incubation time is one of the most effective factors in batch biosorption studies to determine equilibrium stage
of the process.
In general, the adsorption capacity increases rapidly in the first 15 minutes and then increases gradually when nearing the equilibrium stage
before becoming near constant at equilibrium.
Convex-up curves with high integrals indicate typical youth, undissected (disequilibrium stage) landscapes, while smooth, s-shaped curves crossing the center of the diagram represent the characteristics of mature (equilibrium stage
) landscapes and concave curves with low integrals exhibit old and deeply dissected landscapes (Strahler, 1952).
The final plateau region indicates the surface biosorption and the equilibrium stage
The third stage is the final equilibrium stage
He uses the balance equations and equilibrium relations to develop models of the chemical process operations from the rate or equilibrium stage
perspective and discusses the engineering operations of separators and heat exchangers.
Comparison of equilibrium stage
and nonequilibrium stage models for reactive distillation.
"We have now come to the equilibrium stage
. Now we are in the process of planning for the fall demand and looking to start building our stocks," the official added.Aa
The conventional distillation sequence shown in Figure 2a results from the use of the Fenske-Underwood-Gilliland shortcut distillation method, optimized by using the rigorous equilibrium stage
model included in the Aspen Plus[TM] RADFRAC Module.
Mary is at an equilibrium stage
with her partnership between her own company and the customer.
Each tray in the column acts as a partial equilibrium stage
accomplishing a portion of the overall separation task.
For detection of thermodynamics behavior, 20 ml of tyrosine solution with different concentrations were injected and the relative [C.sub.R] (which is defined as the [C.sub.t] when the adsorbing is in a relative equilibrium stage
, that is, when the change of [C.sub.t] in 20 min was less than 0.001 mol/l) was detected, and QR was calculated as well for drawing [Q.sub.R] vs.
