Abstract
Ethylene (CH) and acetylene (CH) are crucial materials in the petrochemical industry, obtained through various processes utilizing natural gas and other hydrocarbon fuels. In this research, the Partially Decoupled Process (PDP) has been investigated through Computational Fluid Dynamics (CFD) simulation to analyze the effects of different parameters on the production of acetylene and ethylene. The evaluated parameters included the mass flow rate ratio, fuel preheating temperature, the addition of ethane and propane to the fuel, the addition of H, CO, and HO to the inlet feed and, reducing the jet inlet diameter. The results showed that an increase in the mass flow rate leads to an increase in the mole fraction of C (CH + CH) in the reactor outlet. Furthermore, the substitution of 30 % methane with a combination of 20 % ethane and 10 % propane has resulted in a 6 % increase in the mole fraction of CH, a 43 % reduction in the mole fraction of CH, and a 5.6 % increase in the mole fraction of H at the outlet of the reactor. It was also observed that by decreasing the diameter of the side tubes from 43.3 mm to 20 mm, methane conversion decreases by 1.14 %, and C yield decreases by 46.8 %.
期刊介绍:
Journal of Industrial and Engineering Chemistry is published monthly in English by the Korean Society of Industrial and Engineering Chemistry. JIEC brings together multidisciplinary interests in one journal and is to disseminate information on all aspects of research and development in industrial and engineering chemistry. Contributions in the form of research articles, short communications, notes and reviews are considered for publication. The editors welcome original contributions that have not been and are not to be published elsewhere. Instruction to authors and a manuscript submissions form are printed at the end of each issue. Bulk reprints of individual articles can be ordered. This publication is partially supported by Korea Research Foundation and the Korean Federation of Science and Technology Societies.
