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...

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 ...

Study on the Alkylation of Benzene and Long-Chain Olefin under Trifluoromethane Sulfonic Acid Catalyst by Yanzhen Wang in Progress in Petrochemical Science Abstract: Using trifluoromethane sulfonic acid as catalyst for alkylation of benzene with long chain olefin process were studied. In the self-made alkylation unit, the effects of catalyst dosage, reaction time, reactant volume ratio and reaction temperature on the products were investigated. The results indicate that under the condition of 1v% catalyst dosage, 80 ℃, 20min and the volume ratio of benzene and 1-decene is 8, the conversion of 1-Decene can reach 100%, and the selectivity of 2-LAB is 42.29%. Otherwise, the content of heavy alkylbenzene is small. Washing by water can separate the catalyst from reaction system easily. https://crimsonpublishers.com/pps/fulltext/PPS.000646.php For more articles in  Progress in Petrochemical Science , please click on below link:  https://crimsonpublishers.com/pps/
