Some improved design about the location structure of convection chamber in pyrolyzer of ethylene has been summed,which be good for their stress and easy to manufacture.

A large amount of soot accumulated on the external surface of convection tube surface in the CDU furnace in CNPC Urumqi Petrochemical Company after long-term operation,which greatly reduced the heat transfer efficiency of the convection tubes.

Modeling Simulation and Optimization of GK-V Naphtha Pyrolysis Furnace;

Presents the cracking frequently existed in the welding of the new tubes with old ones of pyrolysis furnace,analyzed the reasons for the cracking from the aspects of chemical composition,metallurgy and mechanical properties,and finally proposes methods to solve the problem.

Control and examination of dichloroethane pyrolyzer installation of 200 kt/a vinyl chloride project;

Self-established sampling system and analysis method of industry pyrolyzer;

A new mathematical simulation approach for tubular reactors in ethylene pyrolyzer;
