摘要
计算了催化裂化装置烟气轮机入口管道不同直径对投资和操作费用的影响,结果表明传统上采用较高线速(30～40 m/s)计算出的管道直径偏高,不具有最优的经济性,应适当降低到20～30 m／s的范围。认为在粗估管径时应采用较低线速进行计算,详细设计时应进行技术经济分析。
The investment and payback were studied for flue gas turbine suction pipelines with different diameters in a FCC unit. The result and analysis showed that the pipe size calculated based upon the higher velocity in the conventional guidelines is not economically optimized, and lower velocity （20-30 m/s） should be used in rough diameter estimate. Techno-economic analysis is required during the detailed design.
