石油烃管式炉裂解技术的核心设计及发展

Development of Pyrolysis Furnace Design for Ethylene Production

以“化学工艺学”——烃类热裂解中管式裂解炉和裂解工艺过程的教学内容为素材,通过对比分析美国Lummus公司、KBR公司和德国Linde-Selas公司管式裂解炉的炉管结构设计,使学生认识到管式裂解炉炉管结构设计不但与烃类热裂解高温、短停留时间和低烃分压的裂解工艺存在着密切的关系,而且是提高管式炉裂解选择性、烯烃收率和裂解原料适应性的关键.另外,结合乙烯装置在控制系统、急冷技术、结焦抑制和节能降耗等技术方面的发展,向学生阐明了未来裂解炉设计的发展方向.

Through comparison and analysis of structural design of pyrolysis furnace of Lummmus, KBR, Linde-Seals company, the students know not only the dose relationship be- tween the structural design of pyrolysis furnace and the pyrolysis technology of high temperature, short residence time and low hydrocarbon partial pressure, but also the structural design of pyrolysis furnace as key factor to improve the cracking selectivity, olefin yield and cracking feedstock adaptability. In addition, the author also introduces the development of other technologies on ethylene production such as control system, quenching technique, coke inhibition technology, energy saving and consumption reducing, which are beneficial to clarify the future development and direction of pyrolysis furnace design for students.
