A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns
Batch distillation often cannot use vapor recompression due to contamination risks in food and pharma. This study proposes a design for integrating closed‐loop heat pumps using natural fluids. Results show significant energy savings, offering a sustainable alternative to traditional setups.

The Exergy Losses Analysis in Adiabatic Combustion Systems including the Exhaust Gas Exergy
The entropy generation analysis of adiabatic combustion systems was performed to quantify the exergy losses which are mainly the exergy destroyed during combustion inside the chamber and in the exhaust gases. The purpose of the present work was therefore:

Mechanical vapor recompression integration in distillation is analyzed, focusing on feed preheating and column pressure drop. Binary methanol–water and benzene–toluene separations are studied to identify optimal designs, which are further assessed in a bioethanol vacuum distillation sequence regarding energetic, ecological, and economic performance ...

A New Numerical Approach for Exergy Targets and Losses Determination in Sub-Ambient Processes
Sub-ambient processes such as a refrigeration system are a highly energy intensive area in chemical industries. Refrigeration systems require a high level of process cooling using a combination of compression and expansion operations.

All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...
