Absttract The calculation and control of over evaporation in crude oil distillation units are reviewed in this paper. On the basis of different crudes and different processing schemes, control temperatures at the outlet of heater coil to atmospheric tower can be obtained by calculation or direct measurement. These outlet temperatures are very important for product yield and quality as well as the fuel saving.

本文介绍了常减压装置原油蒸馏塔的过汽化率计算及控制。根据对不同原油,不同的加工方案、通过计算或直接测量常压塔过汽化率来合理给出常压炉出口温度控制指标,既能保证产品收率和质量,又能节省燃料油。据兰州炼油厂常减压装置试验情况,按每日6500吨处理能力计算,降低常压炉温5℃后,可节省燃料油2~3吨/日,价值90~135元/日。

The achievment of the energy saving program in force for many years for crude oil distillation units in domestic refineries. are reviewed. The average energy consump tion of crude units has dropped from 283 MKcal to 169 MKcal per ton of crude oil which is equivalent to a saving of 800 thousand tons of fuel oil per year. The energy usage of crude distillation unit are analyzed and various energy saving techniques are discussed based on an energy model consisting of three main links,i.e. energy conversion, process energy consumption and energy recovery. Accordingly, some aspects of farther energy saving in prospect are suggested.

A dynamic model of a crude oil distillation column is established by identifica-tion.The process is analyzed and a description of simplified MISO System isobtained.Dynamic tests are carried out by use of P.R.B.S.and models areidentified.Several methods are compared with each other.Many results show thatthe identification of practical industrial process by simple methods is feasible andthe models have been successfully used to practical process.Some successfulmethods and experience are presented.

本文叙述我们通过系统辨识方法建立了大型炼油蒸馏塔的动态模型。首先结合工艺分析给出简化的多输入单输出模型结构,然后用 PRBS 输入分别进行单通道和多通道扰动试验,再经辨识获得了蒸馏塔模型。系统辨识过程中,我们针对某一通道就几种不同的辨识方法进行了比较,证明用简单的方法,在一定条件下对实际工业过程建模是可行的,所获模型经验证也是可靠的,并在实际生产中取得了良好的应用。这就为实际工业过程建模提供了成功的经验和方法。
