毕业设计200万吨催化裂化装置分馏系统工艺设计摘要PAGEIIPAGEI摘要随着世界经济发展，环境问题日益突出，同时能源需求日益旺盛，各国对汽油等轻质油特别是高质量的清洁燃料的需求量急剧增加，同时随着石油化工业的发展，需要多产轻质油.将重质油更多的转化成轻质油品，且转化成清洁能源是以后催化裂化领域的重要课题。催化裂化是石油炼制过程之一，是在热和催化剂的使用下使重质油发生裂化反应，转变为裂化汽，汽油和柴油等的过程.本设计题目是200万吨/年催化裂化分馏及换热装置的工艺设计.所用工艺对重油加工程度较深且产品收率很高，同时具有较好的经济效益和环保效益，同时以大庆常压渣油为原料生产高质量汽油的方案通过综合评定后的经济效益较为合理，通过汽油的方案及反一再系统工艺的计算，达到了设计的目的。本设计加工弹性大，汽油产率较高，并充分考虑了能量的综合利用问题与环境保护问题关键词：重油催化裂化分馏塔舌形塔板AbstractAstherapideconomicdevelopmentofChina,moreandmoreattentionaretakentotheworld'senvironmentalproblems,leadingwithgasoline,lightandsweetoilespeciallyforbetterqualityofcleanerfuelsdramaticlyincreaseindemand,whilethedevelopmentofpetrochemicalindustryneedsmoreeffectivelyprolificlightoil.HowtotransformmoreheavyoilintolightoilandcleanenergyistheimportanttopicsoffutureFCC.FCCisoneofthepetroleamrefiningprocessistheuseofheartandacatalystforheavyoilundercarckingreactionoccurs,intoasteamcracker,suchasgasolineanddieselprocess.Thetopicofthisdesignis2milliontons/yearofFCCprocessdesign.Therearedeeperontheprocessingofheavyoilandhighyield,andcomprehensiveevaluationofeconomicbenefitsarereasonablebyDaqingatmosphericresidueasrawmaterialstoproducegasolineprogram,aimedatproducinghigh-qualitygasoline.Gasolineprogramandanti-andthenthecalculationoftheprocesssystemtechnologyandisdesignedtoreach.Theflexibledesignandprocessinghashighyieldofgasoline,andgivefullconsiderationtothecomprehensiveutilizationofenergyandenvironmentalissues.Keyword:catalyticcracking;Mainfractionator;Tongueshapedtowerboard目录目录TOC\o"1-3"\h\uHYPERLINK\l"_Toc327254715"摘要PAGEREF_Toc327254715\hIHYPERLINK\l"_Toc327254716"AbstractPAGEREF_Toc327254716\hIIHYPERLINK\l"_Toc327254717"第一章概述PAGEREF_Toc327254717\h1HYPERLINK\l"_Toc327254718"1.1催化裂化工业的意义与作用PAGEREF_Toc327254718\h1HYPERLINK\l"_Toc327254719"1.2催化裂化技术国内外发展现状PAGEREF_Toc327254719\h1HYPERLINK\l"_Toc327254720"1.3催化裂化工艺简介PAGEREF_Toc327254720\h2HYPERLINK\l"_Toc327254721"1.4设计依据PAGEREF_Toc327254721\h2HYPERLINK\l"_Toc3272
