No parece estar muy bien. Parece ser un contenido de química física,

Tu comprens解释是对的。你的假设不成立,22℃时甲苯的饱和蒸汽压P1较小,如气相空间压力是P1,那么甲苯罐处于真空状态,你的的储罐能承受吗?再说,你的的储罐是固定顶罐还是,内浮顶罐,内浮顶罐就不存在你说的甲苯损失情况。

不一定是要甲苯,也不一定是20度,可以认为饱和蒸汽压大于大气压的,只是做个例子,你觉得我的理解对的吗?

本帖最后由 chen5714355 于 2020-10-13 14:54 编辑 “如果认为顶部排气流量是不变的话,其实氮封是无法降低甲苯的损耗的“ 个人认为这个假设不合理,储罐压力由P1增大到P2排气量不变必然要关小排气阀,通氮气后排出的气体是氮气和甲苯的混合气,如果控制同样的流量应该甲苯流出应该减少,但氮气有损耗
