一、概述齐鲁石化总公司炼油厂催化裂化装置原设计是120万吨/年的Ⅳ型装置,1967年投产,十几年来作了几次改造。目前的装置水平是:①采用了20%3A 剂及80%Y-9催化剂,使用了一氧化碳助燃剂。②再生压力为1.5公斤/厘米~2(表),稀相段温度为640℃左右,风量为2000/分标米~3左右。③处理能力为130-140万吨/年。能耗约为75万千卡/吨进料。由于主风机增至三台,操作较复杂,且电耗达37.1度/
I. Overview Qilu Petrochemical Corporation refinery catalytic cracking unit was originally designed 1.2 million tons / year of Ⅳ-type device, put into operation in 1967, more than a decade to make a number of transformation. The current installation level is: ① using 20% 3A agent and 80% Y-9 catalyst, the use of carbon monoxide combustion improver. ② regeneration pressure of 1.5 kg / cm ~ 2 (table), the dilute phase temperature of about 640 ℃, the air volume of 2000 / sub-standard meters ~ 3 or so. ③ processing capacity of 130-140 tons / year. Energy consumption is about 750,000 kcal / tonne feed. As the main fan increased to three, the operation is more complicated, and the power consumption of 37.1 degrees /
