Optimal design of reduced vapor transfer dividing wall structures with and without heat integration
AIChE Journal, Volume 70, Issue 11, November 2024.Abstract A dividing wall column (DWC) is a prime example of process intensification, whereby significant energy and cost savings can be achieved for some systems compared to operation in conventional design of two columns in series. It has been theorized that the vapor and liquid thermal coupling streams in the DWC could be replaced by liquid‐only ...

Evaporation of Binary Mixtures in a Pillow Plate Thermosiphon Reboiler
Chemie Ingenieur Technik, Volume 96, Issue 10, Page 1353-1363, October 2024.Pillow plate heat exchangers are promising alternatives to known heat exchanger geometries and are increasingly used in the process industry. The operational performance of a pillow plate thermosiphon reboiler during the evaporation of mixtures is studied experimentally and an approach for modeling the evaporation‐side heat transfer is discussed ...

Analysis of heat pumps with zeotropic refrigerant mixtures by taguchi method
, 2010 The goal of this work is to determine the optimum set of parameters by using the Taguchi method in vapour compression heat pump systems. The experimental apparatus consist of an air-to-liquid vapor compression heat pump, a water cooled condenser, a forced air evaporator, an electrical air and water heaters, and various measuring elements and other ...

The Dependence of the Feasible Separation Region on Feed Quality and Column Equipment
Chemical Engineering Transactions, 2018 For zeotropic mixtures with C- or U-shaped distillation lines, the feasible separation region is bound by two elements: a product composition multitude and a generalized distillation limit. The generalized distillation limit demarcates the sloppy splits (
