Design of Ethylene Tower
Abstract： The content of this design is the design of ethylene tower. Uses a Ф 1200 float valve tower. The design pressure is 3.6MPa. The tower for the operating medium is CH4、C2H6、C2H4、C3H8、C5H8.Design method using the conventional design method of pressure vessel.According to GB150-98《Steel pressure vessel》technical enforcement.Design content mainly includes the overall scheme, material selection, structure design, parts design, strength and stability checking. Tower equipment is an very important operation unit in chemical industry and petroleum industry. Tower equipment is for mass transfer and thermal transfer by making gas and liquid amply contact each other. Such as the operation of rectification, absorbing, extraction and washing can be completed by tower equipment. Float valve tower with large elasticity of operation, high efficiency, good processing ability, entrainment with small, easy to adjust, and simple structure the advantages of easy installation. Widely used in modern chemical tower.
