【摘要】：現(xiàn)在世界各國普遍提高了對汽油性質(zhì)的要求,催化重整是以石腦油為原料生產(chǎn)高辛烷值汽油組分和芳烴的重要手段,同時可向聚丙稀和加氫裝置提供大量廉價的氫氣,是世界各國石油化工廠和煉油廠的重要工藝之一。連續(xù)重整原料預(yù)處理是連續(xù)重整裝置的一個重要組成部分。介紹了預(yù)處理和催化重整單元的流程、工作原理及技術(shù)特點;針對重整裝置預(yù)處理部分運行過程中所遇到的問題,判斷和分析預(yù)處理單元壓降逐漸增大的原因,同時提出了增加除氧系統(tǒng)的方案。然后從改造方案的設(shè)計、裝置平面的布置、主要設(shè)備的選擇、自動控制的改造等方面對延安石油化工廠連續(xù)重整裝置進行改造;然后對除氧系統(tǒng)投用初期存在的問題提出解決方案并處理。通過對熱力除氧系統(tǒng)的投用,預(yù)處理部分運行情況良好,說明連續(xù)重整裝置預(yù)處理壓降大的技術(shù)瓶頸得以解決。系統(tǒng)壓降基本不變,避免了預(yù)處理頻繁換劑、撇頭;為裝置的平穩(wěn)長周期運行奠定了堅實的基礎(chǔ),實現(xiàn)了可觀的經(jīng)濟效益,達到了預(yù)期目的,說明熱力除氧改造項目是成功的。
[Abstract]:Nowadays, the demand for gasoline properties has been raised in the world. Catalytic reforming is an important means of producing high octane gasoline components and aromatics from naphtha, and can provide a large amount of cheap hydrogen to polypropylene and hydrogenation units at the same time. Continuous reforming feedstock pretreatment is an important part of continuous reforming unit. The process, working principle and technical characteristics of pretreatment and catalytic reforming unit are introduced. In view of the problems encountered in the operation of the preprocessing part of the reforming unit, the reasons for the gradual increase of the pressure-drop of the preprocessing unit are judged and analyzed. At the same time, the scheme of increasing the oxygen removal system is put forward, and then the design of the revamping scheme and the layout of the unit plane are presented. In the aspects of selection of main equipment, transformation of automatic control and so on, the continuous reforming unit of Yanan Petrochemical Plant is reformed, and then the solutions to the problems existing in the initial period of operation of the deoxidizing system are put forward and dealt with. Through the application of the thermal deoxidizing system, The operation of the pretreatment part is good, which shows that the technical bottleneck of large pressure drop in pretreatment of continuous reforming unit can be solved, the pressure drop of the system is basically unchanged, and the frequent change of agent and skimming head are avoided. It lays a solid foundation for the steady and long period operation of the plant, realizes considerable economic benefits and achieves the expected purpose. It shows that the project of thermal deoxygenation reform is successful.
