Design of heptane separate column
Abstract: Tower equipment is a kind of important unit operation equipment in chemical, petrochemical and refining, and other industrial department. The design of the tower equipment means mechanical design. The problem to solve in Mechanical design is determine the details of the tower equipment structure outside, another important task is to do all kinds of work check, in order to ensure that the design of the tower equipment can not only finish the normal operation, and must comply with the national safety production standards.
Complete body of the column plate structure design is part of pressure vessels design, namely calculation of the tower wall thickness, design of the column accessories, and took over the design, etc.
Auxiliary equipment and accessories structure design: take over the design and the related flange of selecting, except the foaming machine, manhole and its annex design.The tower check includes, tower quality and natural vibration period of calculation, earthquake loads and seismic moment, the wind load and the wind bending moment calculation,etc.
Key words: structural design; assist device ; attachment; screen panel tower
