Abstract

Ethylene and acetylene are important raw materials in the chemical production process, but the wide explosion limit makes them dangerous. In order to improve the safety in the process of production, storage and transportation, the pressure and flame characteristics of different concentrations of ethylene-air and acetylene-air explosion venting and flameless venting are studied. The pressure evolution mechanism, the flame propagation behavior during the ordinary explosion venting process and the flame quenching mechanism of the ethylene-air and acetylene-air in the micro-channel in the flameless venting equipment are revealed. The research results show that the flameless venting equipment can take account of the quenching of high-temperature vented flame and high efficiency of venting, significantly reduce the environmental pressure and effectively protect the surrounding environment, and safety design model is proposed by modifying NFPA 68, which could provide reference to engineering.

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
