Analysis and calculation of Design and Structure of Cold Box for Air Separation Equipment

Taking for example the 28000 m3/h air separation engineering of Datang Hulunbeier Co.,the mechanical property variation and design principle of structural steel under low temperature were analyzed to determine steel quantity of a cold box.Taking for example Sudan's 2000 m3/h liquid air project done by China National Air Separation Plant Co.,Ltd.,various loads of the cold box structure were calculated to determine design of every part.
