粗苯脱重工艺研究
摘 要
粗苯脱重就是苯精制的第一步,粗苯进入脱重塔后,经蒸馏,达到重苯与轻苯的分离,使得对苯精制基本无用的重苯从粗苯中分离出来。本文主要以粗苯为原料,采用精馏的方法,将粗苯中的重苯与轻苯分离,使蒸出的轻苯更加符合催化加氢的生产。通过不断改变脱重塔的压力与温度,找到粗苯脱重最合适的温度与压力范围。实验中不断改变脱重塔的压力与温度,检测塔底重苯中三苯的含量,得出不同温度、压力下的蒸馏效果。
实验得出的结论为:粗苯脱重的最合适压力范围-45KPa至-55KPa,最合适温度为170℃。阻聚剂添加10~20ppm可有效防止物料的聚合结焦。
关键词:苯加氢 粗苯 精馏

Process of crude benzol off weight
Abstract
Crude benzol off weight is benzene refining step, the crude benzol enter off Pagoda, distilled, heavy benzene and light benzene separation of benzene refined useless re-benzene separated from crude benzol. In this paper, crude benzene as a raw material, distillation method, the weight of benzene in crude benzol and light benzene separation, so that the steam out of the light benzene more in line with the catalytic hydrogenation of production. Off weight the most appropriate temperature and pressure range by changing the pressure and temperature off Pagoda, find crude benzol. Changing the experiment off the the Pagoda pressure and temperature, detect bottom heavy benzene the triphenyl the content, and arrived at a different temperature, under the pressure of the distillation effect.
Experiment the conclusion is: the crude benzol off the most appropriate pressure range of-45KPa to-55KPa, the most suitable temperature of 170 ° C. Inhibitor to add 10 to 20ppm can effectively prevent the aggregation of coke materials.
Key words: benzene hydrogenation crude benzol distillation

the reaserch of process of crude benzene to reduce liquid
abstract
reduce liquid of crude benzene is the first step of refining benzene, crude benzene went into tower of reducing liquid ,after distilling cude benzene and light benzene divided, so that crude benzene which is not used to refining benzene is divided out . in this paper ,authour treat crude benzene as raw meterial ,use refining benzene method , divide crude benzene and light one ,so that light benzene can be fitted catalytic hydrogenation's produce better . we change temperature and pressure of reduce liquid tower countinuous ,nad find out the best temperature and pressure for reducing liquid of crude benzene .in the test ,we got sffect of distillation under different temperatures and pressures acoording to change the temperature and pressure in tower and check tri-benzene's content in crude benzene under tower .
at last ,the couclusion of test is that the best pressure range for crude benzene reducing is -45KPa to -55KPa ,and best temperature is 170c .adding 10-20 ppm polymerization inhibitor can be stop it polymerizing and coking effectively .

Removal of heavy crude benzol process research
Abstract
Removal of heavy crude benzene refining is the first step in dewatering tower, Crude Benzol, by distillation, to heavy benzene and light benzene separation, makes the benzol refining basic useless heavy benzene benzol separated from. This paper mainly in crude benzene as raw material, uses the distillation method, the crude benzol in heavy benzene and benzene separation, make steamed out of the light benzene catalytic hydrogenation to produce more in line with the. By changing the temperature and pressure from the heavy tower, find the crude benzene removing heavy most suitable temperature and pressure range. Experiments in changing from the heavy tower pressure and temperature, detection of tower bottom heavy benzene three benzene content, different temperature, under the pressure of the distillation effect.
The obtained conclusion: crude benzol and weight is most appropriate pressure range of -45KPa to -55KPa, the most suitable temperature was 170 ℃. Inhibitor adding 10~20ppm can effectively prevent the material polymerized coke.

Coarse benzene taking off heavy process research pick to cuben take off heavy is the first step of benzene refined, coarse benzene into heavy tower off after the distillation, benzene and light weight to the separation of benzene, which makes the benzene refined basic useless heavy benzene from coarse benzene separated. This paper mainly coarse benzene as raw material, using distillation method, the heavy cuben benzene and light benzene separation, make steamed out light benzene more in line with the catalysis hydrogenation production. Through the changes of pressure and take off heavy tower temperature, find thick benzene taking off heavy the most appropriate temperature and pressure range. Experiments change to take off the heavy pressure and temperature of the tower, testing the bottom three benzene in heavy benzene content, got a different temperature, pressure distillation effect. The obtained conclusion is: coarse benzene taking off heavy pressure range-the most appropriate 45 to 55 KPa KPa, the most suitable temperature of 170 ℃. The polymerization retarder resistance add 10 to 20 PPM can effectively prevent the material of coked polymerization.
