5万吨年环氧乙烷固定床设计方案.doc

摘 要 环氧乙烷是乙烯的重要衍生物，主要用作有机合成的中间体和原料，用于制造乙二醇、表面活性剂、洗涤剂、增塑剂以及树脂等。我国环氧乙烷生产能力有限，每年都要大量进口环氧乙烷产品来满足国内市场的需求。 环氧乙烷是乙烯衍生物中的重要基础化工原料，它主要用来生产乙二醇，因此环氧乙烷（EO））Abstract Ethylene oxide ethylene derivatives, mainly used for organic synthesis intermediates and raw materials for the manufacture of ethylene glycol, surfactants, detergents, plasticizers, and resins. Chinas ethylene oxide production capacity every year to import large quantities of ethylene oxide products to meet domestic market demand.。 . Ethylene oxide is an important basic chemical raw materials in the ethylene derivatives, it is mainly used to produce ethylene glycol, ethylene oxide (EO)/ethylene glycol (EG) process is one of the important process in the petrochemical industry. China now has 11 sets of varying sizes EO/EG production unit, but compared to similar devices in the foreign and backward technology of these devices, energy and water consumption higher, so the researchers EO/EG process optimization to reduce production costs. a very real sense.。 The designed annual production capacity of 50,000 tons of ethylene oxide synthesis section in the process design. And ethylene oxide production, production principle, the process routes and major equipment, etc. are discussed and calculated. The design process is divided into four systems, namely: the reaction system, the absorption and desorption of ethylene oxide system, carbon dioxide absorption desorption system and sophisticated system of ethylene oxide. Line and the four system-based process described。 This design feature is off the light components of the tower of ethylene oxide and ethylene oxide fine Tata bottom reboiler heat balance and equipment for thematic mandates calculation of device parameters, proofreading, and calculatedthe results of the heat exchanger, ethylene oxide fine bottom reboiler equipment selection.
