摘要
大港石化公司对 12 0万t/a催化裂化装置进行了UOP技术改造。其喷嘴为改造的重要部分 ,采取喷嘴套筒与提升管整体预制的方法 ,达到了预期的效果。文章详细介绍了喷嘴段提升管预制、喷嘴套筒预制。
The UOP on a 120×10 4t/a catalytic cracking unit was reformed by Dagang Petrochemical Company. Intechnology reforming, the nozzle is a important part. The anticipant effect was acquired with a method to prefabricate whole nozzle casing & riser. The prefabrication of riser in nozzle section, the prefabrication of nozzle easing, the welding of easing & riser and the installation of nozzle were introduced in detail with this paper.
