Conceptual analysis of single-feed heterogeneous distillation columns

Ingeniería e Investigación, 2015
Separation in heterogeneous distillation columns is attained by interaction of two liquid and one vapor phases, interaction of three phases involves complexities due to the determination of vapor-liquid-liquid equilibrium and hence, in the design of ...

Unveiling the Molecular Origin of Vapor-Liquid Phase Transition of Bulk and Confined Fluids

Molecules, 2022
At temperatures below the critical temperature, discontinuities in the isotherms are one critical issue in the design and construction of separation units, affecting the level of confidence for a prediction of vapor–liquid equilibriums and phase ...

MILP APPROACH FOR THE DESIGN OF VERTICAL VAPOR-LIQUID SEPARATION VESSELS- COMPARISON WITH HEURISTICS

Latin American Applied Research - An international journal, 2020
In this article we compare results from different heuristics approaches for the design of VLE separation vessels. In addition, we present an MILP model that embeds the aforementioned heuristics and considers the discrete nature of the geometric variables. We show that different heuristics render different results.

Surface-Engineered Inorganic Nanoporous Membranes for Vapor and Pervaporative Separations of Water–Ethanol Mixtures

Membranes, 2018
Surface wettability-tailored porous ceramic/metallic membranes (in the tubular and planar disc form) were prepared and studied for both vapor-phase separation and liquid pervaporative separations of water-ethanol mixtures.

Hydrodynamics of vapor-liquid flows in curvilined channels of separation devices of power plants

Naukovyi Visnyk Natsionalnoho Hirnychoho Universytetu, 2023
The main factor that affects the efficiency of the separation process is the lack of contact with the surface of the shutter when moving in the flow of small droplets of wet steam. This process depends on the physical and chemical properties of the wet vapor, the dispersion of the droplets, the parameters of the movement of the two-phase medium ...

Separation of aromatics from n-alkanes using tricyanomethanide-based ionic liquids: Liquid-liquid extraction, vapor-liquid separation, and thermophysical characterization

, 2016
Ionic liquids (ILs) have been extensively studied as replacements to sulfolane in the separation of aromatics from alkanes. The employment of ILs could reduce energy requirements and operating costs of the aromatic extraction unit as a result of their ...

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 (

Process intensification by integration of distillation and vapor permeation or pervaporation - An academic and industrial perspective

Results in Engineering, 2022
Since membrane separations, such as vapor permeation (VP) or pervaporation (PV), are not limited by vapor-liquid equilibrium, their coupling with distillation can exert a synergistic effect, overcome the thermodynamic limits of distillation, and improve ...

Thermodynamic Equivalence Validation of New Fpdwcs with Two Partition Walls

Chemical Engineering Transactions, 2018
Four-product dividing wall columns (FPDWCs) with two partition walls is shown to be energy efficient compared with conventional column sequence for multi component separation. However, its industrial implementation is restricted due to two uncontrollable
