Claims (7)
- 圧縮機(10)を清浄化するための方法であって、前記圧縮機(10)は少なくとも一つの圧縮機段(11,12,13)を備えると共に作動媒体(14)を圧縮するために機能し、前記圧縮機(10)の少なくとも一つの圧縮機段(11,12,13)において、前記作動媒体(14)のための圧縮動作中に、ドライアイス、すなわち固体CO2が、清浄化される各圧縮機段(11,12,13)のアセンブリの研磨清浄化のために利用され、液体CO 2 が前記各圧縮機段(11,12,13)内に導入され、前記液体CO 2 は、等エンタルピー膨張によってドライアイスおよびキャリアガスに変換され、前記ドライアイスは、前記キャリアガスを介して、その研磨清浄化のために、清浄化される前記各圧縮機段(11,12,13)のアセンブリへと方向付けられることを特徴とする方法。
- 少なくとも一つの圧縮機段(11,12,13)を清浄化するために、内部的にあるいは前記圧縮機の圧縮動作中に抽出されるドライアイスと、内部的にあるいは前記圧縮機の圧縮動作中に抽出されるキャリアガスとが、前記各圧縮機段(11,12,13)を清浄化するために使用されることを特徴とする請求項1に記載の方法。
- 前記圧縮機(10)がCO2を圧縮する役割を果たし、高圧側圧縮機段の下流で、超臨界圧縮されたCO2が最初に液化され、続いて個体CO2およびガス状CO2へと変換され、このプロセスで取り出されたガス状CO2はキャリアガスとして使用され、かつ、前記プロセスで取り出された固体CO2は低圧側圧縮機段を清浄化するためのドライアイスとして使用されることを特徴とする請求項2に記載の方法。
- 液体CO2は二つの部分流へと分割され、第1の部分流(18a)は固体CO2およびガス状CO2へと変換され、かつ、第2の部分流(18b)は、固体CO2およびガス状CO2への変換前に前記第1の部分流をさらに冷却するために、膨張によって冷却されることを特徴とする請求項3に記載の方法。
- 少なくとも一つの圧縮機段(11,12,13)を清浄化するために、外部的にあるいは前記圧縮機の圧縮動作の外で得られるドライアイスおよび/または外部的にあるいは前記圧縮機の圧縮動作の外で得られるキャリアガスが、前記各圧縮機段(11,12,13)を清浄化するために使用されることを特徴とする請求項1に記載の方法。
- 少なくとも一つの圧縮機段(11,12,13)を清浄化するために、外部的にあるいは前記圧縮機の圧縮動作の外で得られるドライアイスと、外部的にあるいは前記圧縮機の圧縮動作の外で得られるキャリアガスとが、前記各圧縮機段(11,12,13)を清浄化するために使用されることを特徴とする請求項5に記載の方法。
- 少なくとも一つの圧縮機段(11,12,13)を清浄化するために、外部的にあるいは前記圧縮機の圧縮動作の外で得られるドライアイスと、内部的にあるいは前記圧縮機の圧縮動作中に圧縮された作動媒体から抽出されるキャリアガスとが、前記各圧縮機段(11,12,13)を清浄化するために使用されることを特徴とする請求項5に記載の方法。
