摘　　要：针对中原油田石化总厂催化裂化稳定塔塔顶冷却负荷不足的特点,对稳定塔塔顶压力控制方案进行了改进,用凉干气代替热液化气作为旁路介质,提高了稳定塔塔顶冷却负荷。According to the insufficiency of the air cooler cooling capacity of FCC stabilizer top, the pressure control scheme of the stabilizer top was altered. . The warm LPG was replaced by cool dry gas as the bypass medium, which increased the cooling capacity of the stabilizer top.
