大型空分装置往往配套大型液氧液氮贮槽,一般容积在1000m3以上,其对外送液管道减少汽化损失,防止低温液体汽化后对泵产生气蚀是设计中的重点,本文对液体贮槽至后备泵间管道的保冷设计提出了优化方案。 Large-scale air separation plant is often equipped with large liquid nitrogen liquid nitrogen tank, the general volume of more than 1000m3, the external liquid pipe to reduce vaporization losses, to prevent cryogenic liquid vaporization of the pump cavitation is the focus of the design, the liquid tank To the backup pump pipeline cooling design put forward the optimization program.
