我厂2~#FON-150/600-Ⅱ空分塔,自1988年安装投用后,对负荷变动的适应能力较差。工况经常发生波动,轻则影响产量数小时,重则几天无法出氧甚至被迫停车加温。我们多次观察分析并制定操作对策,收到较好效果(见1990年第3期《深冷技术》)。但从1995年开始,该塔工况又发生紊乱,波动的主要表现总是从下塔开始。 I plant 2 ~ # FON-150/600-Ⅱ air separation tower, put into use since 1988, the ability to adapt to changes in load is poor. Frequent fluctuations in operating conditions, ranging from a few hours of output impact, heavy days can not be oxygen or even forced to stop heating. We have repeatedly observed and analyzed and developed operational measures, received good results (see 1990, No. 3 “Cryogenic Technology”). However, the turmoil in the tower started to take place again in 1995 and the main performance of the turmoil always starts with the next tower.
