乙炔装置生产堵塞原因分析及对策

CAUSE ANALYSIS AND COUNTERMEASURES FOR PLUGGING IN OPERATION OF ACETYLENE PLANT

针对影响乙炔生产长周期运行的堵塞问题,分别从原料、天然气裂解、加工处理、检修等方面分析了造成乙炔生产堵塞的原因,指出了原料中的硫、副产炭黑、聚合物、铁锈等是造成系统堵塞的主要因素,并针对存在的问题提出了解决措施。

Focusing on the plugging problem which affects the long-term operation of acetylene plant,this article analyzes the reasons for plugging in acetylene plant from aspects of feedstock,natural gas pyrolysis,processing and maintenance,identifies the main factors resulting in the plugging including sulfur in feedstock,by-product carbon black,polymers and rust,and provides solutions for each specific problem.
