近年来各个炼油厂普遍利用馏分油催化裂化装置掺炼渣油或加工重油,由于原料变重,不仅残碳增加,重金属含量增大,从而使焦炭产率上升,轻质油收率下降,而且雾化蒸汽量增多,主风用量增大,电能消耗增加,实践证明,改进RFCCU进料喷嘴为关键问题之一.2 反应进料喷嘴的选择我厂的RFCCU炼油装置始建于1991年,1993年4月份投产,主要产品是汽油、柴油、附产品是液化气、油浆.主要能源消耗是蒸气、电、风,主要辅助原料消耗是催化剂.这套RFCCU装置的反应进料喷嘴,原是用80年代先进的喉管式喷嘴,近年随着重油催化裂化的普及,对于反应进料的雾化喷嘴的雾化效果提出了更高的要求,专家们相继开发出各种形式的更先进的雾化喷嘴,有多孔Y型喷嘴,KH型喷嘴,引进的TOTAL喷嘴,LPC-1
In recent years, all refineries commonly use distillate catalytic cracking unit blending residue or processing heavy oil, due to heavier raw materials, not only increase the residual carbon, heavy metal content increases, so that the coke yield rose, light oil yield decline, and Increasing the amount of atomized steam, increased the amount of the main wind, power consumption increases, practice has proved that improving the RFCCU feed nozzle is one of the key issues .2 reaction feeding nozzle selection I plant RFCCU refinery was built in 1991, 1993 The main products of this RFCCU unit are the reaction feed nozzle, which was originally put into operation in April of this year. The main products are gasoline and diesel, and the products are liquefied gas and oil slurry. The main energy consumption is steam, electricity and wind, and the main auxiliary material consumption is catalyst. With the advanced throat nozzle of the 1980s, with the popularization of catalytic cracking of heavy oil in recent years, higher requirements are put forward for the atomization effect of the atomized nozzle of the reaction feedstock. Experts have successively developed various forms of more advanced Atomized Nozzles, Porous Y-Nozzles, KH Nozzles, Introduced TOTAL Nozzles, LPC-1
