Localization Of Ethylene Cracking Furnace Structure Performance Analysis

With china’s economic and social development, increasing demand for petrochemical ethylene production plant to determine the ethylene production have become increasingly demanding. In the process of petrochemical-based, with the focus of large-scale equipment in China. Higher proportion of general major equipment share of investment in the ethylene plant, relying on the introduction of foreign production processes and technology will not only increase the cost of investment, also limits the development of China’s ethylene industry faster and better. Therefore, the large ethylene equipment design and manufacturing localization will be crucial.The tutor group bear the Daqing Petrochemical1.2million tons/year ethylene expansion on project in the steel secondary design tasks involved in the design of the cracker as well as some related framework. Present, according to the design drawings provided by the Task Force has completed the on-site installation work. Secondry design based on the requiristics of the cracking furnace design model, combined with engineering applications, the American design of liquid cracking furnace structure and properties of the in-depth study, with the domestic steel the structural design specification, characteristics and seismic performance of a comparative analysis. Large ethylene equipment in China as well as the introduction, digestion and innovation to provide the necessary preliminary research results.Using an easy to use large-scale computing tools, this method first TEKLA steel structure sofeware-based, three-dimensional entities of the large-scale ethylene cracker computational model, mechanical model, and then import the model into the structure analysis and calculation software the STAAD of. In this paper, the above model to establish the method of calculation and analysis of the cracking furnace is a highly sophisticated industrial equipment, sensitive to earthquakes, several structural forms of modal simulation. Were evaluated by calculating the analytical results, the structural properties and related indicators of the domestic cracker.
