重油催化裂化装置油浆外甩线改造分析

Analysis of Slurry Drawoff Reform of Heavy Oil Catalytic Cracking

油浆正常外甩是控制分馏塔底液位的一个关键参数,也直接影响到装置的安全平稳生产,塔底液位过高,会对反再系统压力产生影响,淹过大油气线后会造成安全事故。就兰州石化公司重油催化裂化装置需对油浆正常的外甩控制阀及相应管线扩径,增加其控制的灵活性的改造问题进行分析,以便创造更大的经济效益。

To control the normal thick liquid is a key index in the fractionating column,also critical to the safety and stablity of the equipment.This article is to analyze the slurry drawoff reform of heavy oil catalytic cracking in Lanzhou Petrochemical Company to achieve the greater profits in production.
