Simulation of Heterogeneous Azeotropic Distillation Process with a Non-equilibrium Stage Model
A rate-based simulation method is developed with the correlation for mass transfer rate, which was obtained in our experiments of the homogeneous and heterogeneous ternary distillation with a sieve tray column. The simulation method is applied to the process of ethanol dehydration with benzene, which consists of a dehydrationand an entrainer recovery column. In the simulation study, the effect ...
متن کاملEfficiency of Non-Azeotropic Refrigerant Cycle
Xin Liu Carlyle Compressor Division Carrier Corporation 6500 Chrysler Drive syracuse, NY 13221 Many researchers have believed and claimed that the application of non-azeotropic refrigerants would increase air conditioning or heat pump cycle efficiency. Some of them have carried out experiments in order to confirm their belief, and especially to provide an approach to air conditioner or heat pum...
متن کاملDividing wall columns for heterogeneous azeotropic distillation
The aim of this work is to implement heterogeneous azeotropic distillation schemes in a dividing wall column (DWC) for a feed mixture of water (W), acetic acid (HAC) and an organic component (X). The original design makes use of X to act as an entrainer to facilitate the separation of water and HAC, and we also propose a DWC design based on this idea. This DWC design reduces the capital cost, b...
متن کاملCopolymerization Using Lipase Catalyst
Enzymatic ring-opening copolymerization of lactones was carried out by using Pseudomonas f luorescens lipase in bulk. In the copolymerizaton of r-caprolactone (E-CL) and b-valerolactone at 60°C for 10 days a copolymer with molecular weight of 3.7 x 103 was obtained and its structure was found to be of random structure having both units from 13C NMR anlaysis. Effects of the feed ratio, the react...
متن کاملSequence selection during copolymerization.
We analyze a simple model for the copolymerization of two chemically distinct monomers that displays a wide variety of product sequence compositions depending on the rate coefficients for the stepwise addition of each monomer to a growing polymer chain. We show that in certain regions of parameter space the copolymer sequence composition depends sensitively on these parameter values, and we com...
