A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns

open access: yesChemie Ingenieur Technik, EarlyView.
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.

Application of Ultrasonic Sensors for Determining the Height of Dynamic Two‐Phase Layers in Tray Columns

open access: yesChemie Ingenieur Technik, EarlyView.
Ultrasonic sensors are evaluated for their applicability in dynamic gas–liquid systems. By comparing sensor data with two independent optical reference methods, their robustness and reliability are demonstrated under varying flow conditions and tray geometries in column systems.

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...
