塔是石化装置中广泛应用的一种设备,塔器由于内件结构复杂,塔体开口数量众多,管口方位设计也比其它的设备要难。本文以曾经做过的某加氢装置分馏塔为例,阐述分馏塔的管口方位设计需要考虑的事项,管口如何合理规划和附塔管线的布置特点。 Tower is a widely used petrochemical plant equipment, tower due to the complex structure of the inner part of the tower opening a large number of nozzle orientation design than other equipment more difficult. In this paper, a hydrotreating fractionating tower which has been used as an example is taken as an example to illustrate the matters needing consideration in the design of the fissure tower nozzle orientation, how to properly plan the flotation and the arrangement characteristics of the pipeline with the tower.
