PIG清焦技术在炼厂加热炉的实践

PIG in the Dark Technology in the Practice of the Refinery Heaters

某厂焦化装置加热炉对流段结焦严重需要清焦,通过比较各种清焦技术的利弊,采用了清焦效果好、对炉管损伤小、工期短、安全环保的PIG清焦技术,清焦后加热炉运行效果良好,延长了装置的开工周期,具有很大的推广价值。

A delayed coking unit of a factory device heaters convection and serious need for the burnt cinders,by comparing all the pros and cons of technology,and scorched by the dark about the effect is good,whether the injury,the shorter,safety and environmental protection of the PIG burnt out after dark,heaters run well,has been extended by the operating cycle,having great value.promote
