| 摘要 |
The invention relates to a method for operating a steam cycle process which is performed in an apparatus according to the invention, which has an evaporator (1) or steam generator for the evaporation of a liquid working medium (A) and an expander (5), which is lubricated by means of a lubricant, for the performance of mechanical work, the method comprising the following method steps: a) the liquid working medium (A) is fed to the evaporator (1), in which it evaporates and is fed to the expander (5) in the form of steam; b) an ionic liquid (B), which at room temperature forms two liquid phases with the liquid working medium (A), is also fed to the expander (5) as a lubricant; and c) the ionic liquid forming the lubricant for the expander (5) is separated from the working medium (A) upstream of the evaporator (1). |
