Impact of Distillation Column Design on Potential for the Integration of Mechanical Vapor Recompression

Chemie Ingenieur Technik, EarlyView.
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 study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction

Random forest regression for catalyst performance prediction and validation of tri‐reforming of methane (TRM)

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Carbon dioxide‐reduced hydrogen can be synthesized through various methods such as dry‐reforming (DRM), steam reforming (SMR), and partial oxidation (POX). Tri‐reforming of methane (TRM) is a promising technology which combines all the above‐mentioned processes for the simultaneous production of hydrogen and syngas with high energy efficiency.

Effect of different flue gas recirculation rates on low‐NOx combustion characteristics: A numerical simulation based on the combustion process of a gas boiler

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract NOx emissions from gas boilers severely impact the environment, and flue gas recirculation (FGR) technology can effectively reduce such emissions, yet the effects of different FGR rates on combustion performance and NOx formation remain unclear. This study thus used numerical simulation (via ANSYS Fluent, adopting the realizable k‐ε turbulence
