Abstract The article deals with the separation systems’ mean boundary from the perspectives of finite-time thermodynamics. We obtained the lower-bound estimates of the minimum energy input for the separation systems that have a specified separation. It is shown that these inputs do not tend toward zero while the concentration of one of the separated mixture’s components tends to one. Separation systems using heat power have ultimate performance. The article provides examples of the obtained estimates’ application.

热质交换和不可逆分离过程的可行模式集

摘要 本文从有限时间热力学的角度讨论了分离系统的平均边界。我们获得了具有指定分离度的分离系统的最小能量输入的下限估计值。结果表明，这些输入不会趋向于零，而分离出的混合物成分之一的浓度趋向于 1。使用热能的分离系统具有终极性能。文章提供了获得的估计值的应用示例。
