1,4丁二醇装置甲醇塔底液酸度的控制

Checkrein of liquid acidity at the bottom of the methanol tower of the 1,4-butanediol plant

为了解决 1,4 丁二醇装置甲醇塔底液酸度太高的问题 ,通过理论分析和大量工业试验 ,找到了有效地降低甲醇塔底液酸度的方法 ,总结出了循环甲醇含水量和反应塔塔盘温度的最佳操作参数 ,经过装置 2个月的运行证明 ,使甲醇塔底液的H+ 浓度比过去降低了 10 0倍以上 ,产品的质量和产量没有降低并且还显著地延长了甲醇塔底的使用时间。

Aiming at reducing the acidity of the liquid at the bottom of the methanol tower,we found a practicable solution to reduce the liquid acidity and optimized the technical parameters on the moisture content of the circulating methanol and tray temperature of the reactor based on theoretic analysis and lots of industrial experiment.After two month of operation,as the result of the experiment the H +'s deepness is over one hundred times lower than before experiment,the lifetime of the methanol tower is prolonged and the quality and the quantity of the product are both improved.
