Qj series amorphous refractory developed by this factory is series insulation castable , which has such advantages as high refractoriness , high crushing strength and small thermal conductivity . this series product is used widely as insultion material for various heating furnace , atmospheric and vacuum furnace and sulfur recovery device in petrocnemical industry Qj系列不定形耐火材料是我厂自行研制的系列保温隔热浇注料，它具有耐火度高，耐压强度高，导热系数小等特点，该系列产品广泛应用于石油化工各类加热炉，常减压炉，硫回收装置等工业窑炉作保温热材料。
Abstract : basic principles , process scheme and main factors affecting operation of the claus sulfur recovery process in refinery were introduced . the recent development of sulfur recovery processes and catalysts were reviewed . in view of the status quo of small capacity and low operation level of domestic sulfur recovery units , technical revamping options suitable for chinese refineries were proposed 文摘:介绍了克劳斯硫回收工艺的基本原理、工艺方法及在炼油厂硫回收中影响操作的主要因素、评述了硫回收工艺及催化剂近期的发展趋势；针对我国炼油厂硫回收装置规模较小，操作水平偏低的现状，提出了适于我国国情的技术改造意见。
In the third , this paper makes a survey on components of the exhausted flue gas and waste heat resource , and discusses the possibility and methods of steam generation and air preheating with the waste heat . and then , the analysis on the advantages and disadvantages of heat recovery plants with conventional steel - water heat pipes and inorganic heat - transfer heat pipes is carried out . the paper also gives a valuation about the plan and features of the design of heat recovery 对余热源排烟的成分和余热资源量进行标定，讨论余热回收产生蒸汽或加热燃烧用空气的可行性和方法，分析常规余热回收技术设计、采用普通钢-水热管和无机传热热管等传热元件的设计余热回收装置的优缺点，并对余热回收设计方案及其特点进行总体评价。
On the theory , the predictive function control method based on the state space is discussed and the simulation results validate the pfc method ' s advantages on robust and anti - jamming comparing with pid method by computer simulation . the application research includes the application of the software of predictive function control ( apc - pfc ) and the software of the multiple - variables predictive control ( apc - hiecori ) . the former were applied in the temperature control chlorinating process and ph control in the process of zymolysis of penicillin , the latter were applied in the advanced control of reclaim equipment of lox in china petroleum & chemical corporation yangzi petrochemical co . , ltd 本文主要从理论和应用两方面对预测控制方法进行了研究，理论方面主要是从预测函数控制的基本原理出发，研究了一般情况下的基于状态空间描述的预测函数控制策略，并通过计算机仿真验证了pfc算法比常规pid算法具有更好的鲁棒性和抗干扰性：在实际工业过程的应用上，又分为两类算法及软件的应用，预测函数控制策略及apc - pfc软件的应用主要以聚乙烯氯化过程的温度控制和青霉素发酵过程的ph值控制为主，多变量预测控制算法和apc - hiecon软件的应用主要以扬子石化公司的液化气回收装置先进控制为主。
