Ethylene gasoline distillation column
Abstract: Tower equipment is important equiptment which is widely used in chemical, oil and other industrial manufacturing. Tower equipment used in industrial tray columns and packed tower, and plate distillation column is used in this design .The design meets the conditions under the premise for the tower equipment structural design, material selection, strength and stability calculations and component design selection. First determined according to the conditions of the tower's wall thickness of the tower body and head, then according to the mass loading of the body to withstand the tower, the quality of load calculation, seismic load calculations, wind load calculations, the natural period of calculation and the strength and stability check and of the tower opening reinforcement calculations .Finally, select and design the annex to the tray of the plate tower structure and tower equipment reasonably.
Key Words: Distillation column; Intensity check; Structure selection；Design calculations
