催化裂化汽提塔的結(jié)構(gòu)設(shè)計(jì)及理論計(jì)算

1、催化裂化汽提塔的結(jié)構(gòu)設(shè)計(jì)及理論計(jì)算I摘要摘要催化裂化裝置是煉油工業(yè)中很重要的裝置。塔設(shè)備就是該裝置中最重要的設(shè)備之一。塔設(shè)備設(shè)計(jì)的好壞直接影響到煉油產(chǎn)品的質(zhì)量和數(shù)量等。板式塔和填料塔塔器按其內(nèi)構(gòu)件結(jié)構(gòu)分為兩大類。常用的板式塔為泡罩塔、浮閥塔、篩板塔等。其中浮閥塔為較為先進(jìn)的板式塔接觸元件，應(yīng)用廣泛。本塔采用浮閥塔設(shè)計(jì)。汽提段的作用是將待生催化劑上可揮發(fā)烴脫除增加輕質(zhì)油收率降低焦炭產(chǎn)量。隨著能源的緊缺催化裂化原料呈現(xiàn)劣質(zhì)化和重質(zhì)化的趨勢(shì)。

2、這對(duì)汽提段的結(jié)構(gòu)和工藝都提出了新的要求。本文針對(duì)汽提塔的結(jié)構(gòu)設(shè)計(jì)問題進(jìn)行了一系列說明，并概述了控制問題和經(jīng)濟(jì)分析。關(guān)鍵詞：催化裂化，汽提塔，結(jié)構(gòu)設(shè)計(jì)，經(jīng)濟(jì)分析催化裂化汽提塔的結(jié)構(gòu)設(shè)計(jì)及理論計(jì)算III目錄第一章前言.....................................................................................21.1催化裂化技術(shù)的發(fā)展現(xiàn)狀..............
