γ射线对塔设备体外不停工监测的硬件系统与软件系统

本文采用IBM PC/XT微型计算机和非标准电路,实现了γ射线对塔设备体外不停工监测的控制、数据采集和数据处理、绘图系统。本文着重介绍了该系统的结构与性能。所涉及的技术内容经实验验证是切实可行的。该系统的开发成功为将γ射线体外不停工监测技术运用于工业实践提供了基础。     

INSIGHT INTO DISTILLATION/ABSORPTION COLUMNS AND FCC RISERS USING GAMMA SCANNING TECHNIQUE

This paper presents the application of gamma ray scanning technique to distillation/absorption columns and FCC risers.The flow regime transition.clear liquid height,froth height.crestliquid height over the exit weir on a V-1 type valve tray and downcomer hydraulics were investigatedusing the scanning device previously developed.The solid distribution and coke deposition were experi-mentally simulated in a FCC riser simulator by employing a three dimensional scanning device devel-oped for the present investigation.The success of this investigation should shed a light forquantifying two-phase contact phenomena in various gas liquid and gas solid two phase flow system.     

化学工程专家石油化工教育家沈复

我国著名的化学工程专家、石油化工教育家、石油大学教授、国家重点学科带头人之一,博士生导师沈复先生到一九九○年已经执教四十五周年了。正当京毕金叶飘飞之际,沈复教授的学生和同事们纷纷向他致敬,祝贺他送走第四十五批学生。学生们衷心表达他们对老师培育之恩的无限感激之情。四十五载岁月悠悠,几度风雨,几多磨难。此时此刻或许沈复教授又在规划着化工教育与科技的未来?
