摘要
催化剂汽提器是催化裂化装置中重要的组成部分,高效汽提技术的应用对催化裂化装置的经济效益和稳定操作都具有重要的意义。文章全面介绍了国内外出现的汽提新技术,并根据其不同的特点进行了分类,分别介绍了各类技术的特点,并分析了汽提技术今后发展的方向,认为具有小流动单元和气固高效接触特点的格栅式和填料式汽提内构件技术和多段汽提技术将是今后汽提技术发展和应用的热点。通过对催化剂汽提研究方法的回顾,认为应该对汽提器内部的流动、传质和反应特性做更深层次的系统研究,以便最终形成更加完善的数学模型和工业设计方法。
Catalyst stripper is the significant component of catalytic cracking unit,therefore application of high-efficient stripping technolo- gy is very important to obtaining economic bene- fit and stable operation of catalytic cracking u- nit.This article gives overall introduction of new stripping technologies at home and abroad and classifies them based on their characteris- tics,describes their unique features separately and by analyzing the future development of the stripping technology,it is believed that the grid type and packed type stripping internal technolo- gy and multi-stage stripping technology with less flow cell and high-efficiency gas-solid contactor shall be a hot pot in future develop- ment and application.In order to establish a per- fect mathematical model and industrial design method,the inside stripper flow,mass transfer and reaction feature shall be deeply and system- atically studied.
