The fluid flow pattern in the titled reactor can be described by the dispersion model, in which the Peclet number is between 20—50, after the measurement of the influences of liquid and gas velocities, reactor diameters, mounting method and fluid properties, on the fluid flow pattern. The results show that the liquid velocity has heavier influence on the back-mixing than the gas velocity, and the back-mixlng in a vertical reactor is about 20%—30% greater than that in a horizontal one. Although the viscocity...

The fluid flow pattern in the titled reactor can be described by the dispersion model, in which the Peclet number is between 20—50, after the measurement of the influences of liquid and gas velocities, reactor diameters, mounting method and fluid properties, on the fluid flow pattern. The results show that the liquid velocity has heavier influence on the back-mixing than the gas velocity, and the back-mixlng in a vertical reactor is about 20%—30% greater than that in a horizontal one. Although the viscocity of fluid has an inversion effect of velocity on Peclet number, there is no magnitude differences in the range of the operating liquid-velocity of the reactor.

It is recommended that intermal nuzzle would be used to remixing gas-liquid in order to increase mass transfer, and it is found that mass transfer result in vertical model is better than that of horizontal, to the CO_2-H_2O system, is increased about three times. So it is recommended vertical or inclined model be used in pilot plant. The gas sparger has more influence on mass transfer, based on the testing resula, it is found...

本研究为磷铵管式反应器冷模试验的一部分.笔者通过在实验室对磷铵管式反应器传质特性的研究,提出在反应吕内增加缩口,使气液进行二次混合以强化气液传质的方法;同时发现,管式反应器采用垂直安装型式其传质效果优于水平安装.对于CO_2—水体系,约增大2~3倍,而且随着管径的增大,这种差异更加明显.因而推荐工业过程中采用垂直或倾斜安装.气体分布器的型式对传质也有很大影响,实验可见,双侧开孔式要比单孔喷嘴式好.

The mass of product oil at retail is generally taken from the calculations through the method of volumetric flow/density inspection. However, this method, which is prone to influences from many factors, may produce a considerable error. Only mass flowmeter can avoid the factors, and increase the metering accuracy. The paper introduces the application of E+H mass flowmeter introduced from Germany by Shiji-azhuang Oil Refinery. Problems on the application of mass flowmeter are analyzed from installation, operation, measuring range and operation environment. The best installation way the paper considered is vertical; if installed horizantally, the outlet end of the meter must be a 1-2 m long straight-line segment, and a gauge pressure of 20 kPa maitained. The heavy metering error will be produced with the product oil e-vaporated passing through the flowmeter, so, the back pressure of flowmeter has to be increased to reduce evaporation and avoid vibration of flowmeter.

在成品油零售计量中,一般采用体积流量与密度测试的方法,冉经过计算求得质量。由于体积与密度测试受多种因素的影响,误差很大。若采用质量流量计则不受这些因素的影响,并可提高计量精度。介绍了石家庄炼油厂引进德国生产的E+H质量流量计的使用情况,从流量计安装、使用、量程和工作环境等方面分析了使用中出现的问题。测量传感器的最佳安装方式应为垂直式,若为水平安装,其出口段必须有1~2m的直管段,且维持20kPa的表压。通过流量计的油品如果发生汽化,将引起较大的计量误差,为此要提高流量计的背压、减少油品汽化以及减少流量计振动。
