Development of a New Two-Phase Fluid Atomizer Nozzle in Pilot Scale for Fluid Catalytic Cracking Process |
|
| چکیده انگلیسی مقاله |
The uniform atomization of FCC feed causes to produces desirable products like gasoline and decreases undesirable products like coke and dry gas. The atomization process caused the selectivity and efficiency of main products to increase. So Design and manufacturing of optimum atomizer system in FCC process are important. According to this idea, A new twin fluid low-pressure atomizer nozzle including the air-assets type of Nozzle was manufactured in RIPI (Research Institute of Petroleum Industry-NIOC Iran ) from small to large scale. The nozzles sizes were categorized with small to large sizes according to water flow rate(4-50 kg/h). The analysis of spray nozzles pattern and droplet size was made by use of Doppler method with using of Doppler laser analyzers. Many tests were carried out for each size of nozzles, and a flow rate of 50 kg/h a specified nozzle was manufactured and introduced. The general configuration of the nozzle is introduced in this manuscript. The experimental data evaluation for nozzles shows that for a water flow rate of 50kg/hr and air of flowrate 1.4 kg/h, The quantity value of Sauter mean-diameter (D32) and arithmetic diameter (D10) for water droplet particles becomes 150 µm and 50 µm respectively. The following assessment on the pilot-scale will help to develop a new atomizer nozzle on large scale. It shall be mentioned that the development of a new atomizer on a large scale is according to experimental data at the pilot plant scale. Minimization of Sauter means diameter (D32) and arithmetic diameter (D10) for water droplet particles will be variables parameters to optimized atomizer nozzle dimension and configuration. |
