摘要:

大型PTA装置受设备单体的制造限制,氧化单元通常设计为两条并联的生产线。以目前全球单体产能最大的300万t/a PTA装置为背景,介绍2个氧化反应单元与1个结晶单元呈“品”字形布置的设计方案,并结合框架结构和管道布置等因素,探讨氧化反应关键平面布置和立面布置。

Abstract:

 In large-scale PTA plants, the oxidation unit is usually designed as two parallel production lines due to the manufacturing limitation of equipment. Based on the PTA plant with the largest single production capacity of 3 million tons/year in the world, this paper introduces the design scheme of two oxidation reaction units and one crystallization unit, focusing on the equipment layout, the coupling design of equipment and structure, the nozzle layout of the slurry equipment and the design of key pipelines.

Key words: PTA plant, equipment layout;piping design
