Modelling and simulation of hydrogen production via natural gas plasma pyrolysis

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Methane pyrolysis simulation model. Abstract Plasma pyrolysis is a cutting‐edge technology that produces hydrogen and solid carbon from methane without emitting carbon dioxide. In this study, we developed a process simulation model in Aspen HYSYS to analyze the behaviour of this technology at the commercial scale.

Durene conversion in a methanol‐to‐jet process: Exploring conversion at 150–350°C over different acid catalysts

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.

Determination of Vibration Properties and Reliable Frequency Estimation for Synchronous Vibrations Through Improved Blade Tip Timing Techniques Without a Once-per-Revolution Sensor

open access: yesSensors
Synchronous vibrations, which are caused by periodic excitations, can have a severe impact on the service life of impellers. Blade Tip Timing (BTT) is a promising technique for monitoring synchronous vibrations due to its non-intrusive nature and ability

Graph‐theoretic reliability index for assessing the impact of capital and operating cost constraints in designing reliable energy hubs

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Component failures in integrated heating and cooling networks impact reliable energy supply. This work studies reliability of heating and cooling systems constrained either by the annualized capital cost (ACC) or by the annualized total cost (ATC).

Green Project Investments and Corporate Responsibilities: Enablers, Challenges, and Strategies for Mitigating Risks

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT To achieve carbon neutrality, it is crucial that private commercial and noncommercial firms also do their bit to adopt and implement green projects (GPs). Nonetheless, there is a lack of scholarly understanding regarding the elements that influence the implementation of GP by private firms, as well as the barriers to GP adoption and strategies
