Abstract
The uniform atomization of FCC feed causes to produces desirable products as like gasoline and decrease undisreable products like as coke and dry gas . The atomization process caused the selectivity and efficiency of main products were increased .So Design and manufacturing of optimum atomizer system in FCC process is important .According this idea A new twin fluid low pressure atomizer nozzle including air-assets type of NOZZLE was manufactured in RIPI(Research Institute of petroleum industry-NIOC Iran ) from small to large scale. The nozzles size were categories with small to large size according to water flow rate(4-50kg/hr) .The analyzing of spray nozzles pattern and droplet size was made by use of Doppler method with using of Doppler laser analyzers. The many tests were carried out for each size of nozzles ,and at flow rate of 50kg/hr a specified nozzle was manufactured and introduced .The general configuration of nozzle is introduced in this manuscript. The experimental data evaluation for nozzles shows that for water flow rate of 50kg/hr and air of flowrate 1.4kg/hr ,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 in pilot scale will help to developed a new atomizer nozzle in large scale. It shall be mentioned that developed of new atomizer in large scale is according to experimental data at pilot plant scale . Minimization of sauter mean diameter (D32) and arithmetic diameter (D10) for water droplet particles will be variables parameters to optimized atomizer nozzle dimension and configuration .
