Transforming Naphtha Steam Crackers for Plastic Waste and Biogenic Feedstocks_Crimson Publishers

Transforming Naphtha Steam Crackers for Plastic Waste and Biogenic Feedstocks by Henrik Thunman in Progress in Petrochemical Science

Abstract:
In an era where sustainability and profitability are crucial, conventional naphtha steam crackers are increasingly challenged by competing processes and stringent environmental regulations. A pioneering approach from Chalmers University of Technology in Sweden presents a promising solution. This innovative method also addresses the inefficiencies of current plastic recycling methods and paves the way for the transition toward a circular economy. The rise of low-cost alternative feedstocks like ethane and LPG, combined with advanced processes like CATOFIN® PDH that offer high selectivity for olefins directly from alkanes, has led to an oversupply of olefins in the petrochemical market. Additionally, the increasing costs associated with fossil CO2 emissions make naphtha steam crackers less competitive than alternative olefin production methods, which have lower carbon emissions. As a result, operators of naphtha steam crackers in the European Union and Japan are shutting down their systems and seeking new market opportunities.

Research Progress on Modification of Hydroxypropyl Cellulose_Crimson Publishers

Research Progress on Modification of Hydroxypropyl Cellulose by Haixue Kuang in Progress in Petrochemical Science Abstract: Hydroxypropyl cellulose, a semi-synthetic organic compound, is classified into high substitution and low substitution variants. Both display distinct physical and chemical traits, making them prevalent in a plethora of industries, including the pharmaceutical, daily chemical, construction, food and many others. For most efficient use of hydroxypropyl cellulose, it is crucial to comprehend and enhance its properties. For this reason, research in the field of hydroxypropyl cellulose modification has become a focal point. This paper provides a comprehensive review of the modification methods of hydroxypropyl cellulose and presents the current state of research in the field of hydroxypropyl cellulose modification, which has important reference value for practical application. https://crimsonpublishers.com/pps/fulltext/PPS.000638.php For more articles in  Progress ...

Process Modelling and Simulation of Reactive Distillation for the Synthesis of High Purity Mono Ethylene Glycol_Crimson Publishers

Process Modelling and Simulation of Reactive Distillation for the Synthesis of High Purity Mono Ethylene Glycol by Jofry Othman in Progress in Petrochemical Science Abstract: This study developed a suitable process modelling technique and simulation model for the non-catalytic synthesis of high purity Mono Ethylene Glycol (MEG) using the Reactive Distillation (RD) process. The feasibility of the RD process is demonstrated for performing the glycol reaction, dewatering and separation indistinguishable from the existing MEG production process with added advantages. Notably, a high purity MEG product of 99.8% is achieved within a single RD column configuration that avoids the need for the make-up of fresh demineralized water as in the current process. A working RD process model is generated that uses the established kinetics model parameters for MEG synthesis in combination with the equilibrium model and thermodynamic parameters in Aspen Plus® software. This included the power-law reactio...
