Numerical Study of the Condensation Length of Binary Zeotropic Mixtures

Energy Procedia, 2015
AbstractHeat exchangers are the main components in refrigeration and liquefaction systems, particularly in the liquefaction of natural gas, where the gas being condensed is a multicomponent mixture. The study of the two-phase condensation region is important for the design of heat exchangers. This paper studies heat and mass transfer characteristics of

Identification of Pressure‐Swing Separation Processes for Azeotropic Mixtures Using Deep Reinforcement Learning

Chemie Ingenieur Technik, Volume 97, Issue 11-12, Page 1094-1102, November 2025.
An autonomous agent trained via reinforcement learning extends flowsheet synthesis capabilities by incorporating distillation columns operating at different pressures. This enables the detection of pressure‐swing strategies, among other efficient separation processes, for a diverse set of azeotropic mixtures.

Performance analysis of a zeotropic mixture ( R290/CO2) for trans-critical power cycle

, 2015
Low critical temperature limits the application of CO2 trans-critical power cycle. The binary mixture of R290/CO2 has higher critical temperature. Using mixture fluid may solve the problem that subcritical CO2 is hardly condensed by conventional cooling ...

New double column system for heteroazeotropic batch distillation [PDF]

, 2009
A new double column system (DCS) operated in closed mode is suggested for heterogeneous batch distillation. This configuration is investigated by feasibility studies based on the assumption of maximal separation and is compared with the traditional batch

Efficient heat integration within discretely heat integrated distillation columns using liquid injection

AIChE Journal, Volume 71, Issue 8, August 2025.
Abstract Electrification of distillation processes through discretely heat integrated distillation columns (D‐HIDiC) is an effective approach to enhance energy efficiency and lower carbon emissions. For separating systems with high temperature lift, multi‐stage compression and inter‐stage cooling are necessary to link the high‐pressure rectifier and ...

Synthesis of heat‐integrated thermally coupled nonsharp distillation using self‐adaptive spherical search

AIChE Journal, Volume 71, Issue 7, July 2025.
Abstract Although thermally coupled distillation (TCD) exhibits strong energy efficiency, the possibility of utility cost savings remains debatable. TCD designs that do not consider vapor transport can underestimate costs, making section rearrangement crucial to find more operable configurations.

Generalized optimization framework for synthesis of thermally coupled distillation columns

AIChE Journal, Volume 71, Issue 6, June 2025.
Abstract In this article, a generalized optimization framework is proposed for the synthesis of thermally coupled distillation systems within an equation‐oriented environment. The proposed framework consists of three components: an efficient superstructure representation, a novel mathematical formulation, and the associated solution algorithm ...

Applying Two-phase Zeotropic Heat Transfer Fluids to Solid-state Cooling Cycle and Comparison with Baseline using Single Phase Water [PDF]

, 2021
Solid-state caloric cooling cycles are considered to be a promising alternative to conventional cooling technology. Theoretically, they can compete with the conventional vapor compression cycle and are much more efficient.
