四川理工学院毕业（设计）论文 200kt/a氯乙烯合成工段工艺初步设计 学 生： 学 号： 专 业： 班 级： 指导教师： 二O一三年六月摘 要 本论文结合国内外聚氯乙烯(PVC)材料应用发展前景，以及先进生产技术，采用电石乙炔法合成本产品。当然，氯乙烯的合成设计到很多的工序，本文根据要求着重对合成工段进行设计，使得氯乙烯的生产更高效更快速的进行。在整个的设计过程中，主要在电石法生产氯乙烯的生产工艺的基础上进行相关的物料衡算、热量衡算、设备选型，并讨论了产生废弃物的处理。目前我国以电石乙炔为原料的聚氯乙烯生产厂共76家，总生产能力124万吨/年[1]。在能源成本愈来愈高以及国内外竞争日益激烈的今天，建立在高能耗电石基础上的乙炔法聚氯乙烯工业正面临严峻考验。 关键词 :乙炔；氯乙烯；电石法；能量衡算；设备选型ABSTRACT This paper combined with polyvinyl chloride(PVC) material application development prospect at home and abroad, as well as advanced production technology, using calcium carbide acetylene method in cost of product.And,of course, the synthesis of vinyl chloride design to many working procedure,according to the requirement of synthesis section to carry on the design,make the vinyl chloride production more efficient and rapid.Throughout the design process, mainly in the production process of the production of vinyl chloride by calcium carbide method,on the basis of material balance,heat balance heat balance calculations ,equipment selection,and waste production processing are discussed. At present our country with manufacturer of calcium carbide acetylene as raw material of PVC,a total of 76,total production capacity of 1.24 million tons/year.In increasing energy cost and an increasingly competitive today,at home and abroad based on energy-intensive calcium carbide acetylene method of polyvinyl chloride(PVC) industry is facing a severe test.
