Reducing Carbon Emissions in Petrochemical Plants

Strategic Insights -

A groundbreaking study has been published by researchers at King Fahd University of Petroleum and Minerals, focusing on the reduction of carbon emissions in industrial plants. The study highlights the critical component of abrupt pipe contraction, which results in significant energy losses. A novel method of analyzing entropy generation using the local entropy generation method has been applied to various Reynolds numbers, demonstrating excellent agreement between differential and integral entropy methods. The research concludes that introducing rounded contractions in pipe designs can significantly reduce energy losses, with reductions of 22% in laminar flow and 96% in turbulent flow.
