实验室加氢反应釜的操作规范

来源: 时间:2021-07-01 15:53:46 浏览次数:

1首先加氢之前一定要检查一下各阀门是否关严; 2要注意将排气软管指向空旷且空气流通的地方; 3上氢气减压阀门(注意氢气压力阀的丝口是反丝的氮气压力阀。上好后,要再次用肥皂水检查是否漏气,如漏气,则要重上; 4排气口用真空抽出液面上的空气;

给高压釜加氢是一项不可缺少的流程,那么,这个操作过程具体有什么操作规范呢?

1首先加氢之前一定要检查一下各阀门是否关严;

2要注意将排气软管指向空旷且空气流通的地方;

3上氢气减压阀门(注意氢气压力阀的丝口是反丝的氮气压力阀。上好后,要再次用肥皂水检查是否漏气,如漏气,则要重上;

4排气口用真空抽出液面上的空气;

5打开釜的进气阀,打开氮气减压阀,充氮气,使内釜压力(P=0.2Mpa后,关闭氮气减压阀,关闭进气阀,坚持约2分钟,看压力表压力是否下降,另外俯首侧听阀门、釜盖是否漏气,如不漏,则缓慢打开排气阀,将里面的压力排泄至0.01Mpa时,关闭排气阀;

6一次重复上述方法5

7打开进气阀,打开氢气减压阀,充入氢气至所需压力,关闭进气阀,关闭氢气减压阀,然后调试其它参数至所需状态令其反应。
