30万吨年乙烯装置乙烯精馏塔冷凝器设计

Design of Ethylene Distillation Tower Condenser for 300,000 TonsYear Ethylene PlantAbstractEthylene industry is the core of the petrochemical industry,ethylene productionis a measure of a country's petrochemical development level of an important indicator.The late seventies,China focused on the introduction of a number of an annual outputof 300,000 tons of large-scale ethylene production plant,the Yangtze ethyleneproduction plant is one of them.Heat exchangers in industrial production occupies an important position for coldand hot fluid for heat exchange.In the ethylene industry is essential equipment.This design is the design of the ethylene rectification tower of the ethylenedistillation column in the ethylene distillation section of the Yangtze ethylene plant.The role of the condenser is to condense the ethylene back to the top of the tower.Design to understand the various heat exchanger type,advantages and disadvantagesand the application of the occasion,taking into account the final use of the kettle fixedtube plate heat exchanger.This design is mainly based on GB /T150-2014 and GB/T151-2014 on the heat exchanger design and verification,the work of the focus onstructural design and strength check.Finally draw the heat exchanger drawing.The design includes:equipment selection,selection,process calculation,mechanical design,and its strength,stiffness,stability check and the use of CADdrawing heat exchanger assembly drawings and parts map.Key words:Heat exchanger;Kettle type;Fixed pipe plate;Process calculation;Strength check
