Isothermal (almost) compression of gas by water injection

    I have found this by searching net. The inventor claimed that by using a new kind of piston fitted with fins, he achieved almost isothermal compression and greatly reduced the power consumption process. I want to know how much theoretically sound it is.

    If it is slow, the cylinder may be able to dissipate heat sufficiently quickly during a compression to prevent significant temperature increase. It requires much less work to compress the gas if heat is dissipated during compression to keep the temperature constant. So whether it works or not depends on how fast the compression is.

    What you have said is already known. But, this process is different. It's sufficiently fast (1500 rpm), but still can control the temperature rise by using water. It's the uniqueness of this technology, which is simultaneously fast and isothermal.

    I thought you were asking whether it is theoretically possible. It is. Whether it actually works is a different question.

    As per the claims on the website, they have done it.

    This seems to be a detailed analysis of a water-injection-cooled compression cycle process: DEVELOPMENT OF A RECIPROCATING COMPRESSOR USING WATER INJECTION TO ACHIEVE QUASIISOTHERMAL COMPRESSION

    Wet bottom compressors and compressors with water injection are old technology . Noah probably used them in his ark .

    Your thread title reflects exactly the topic in the white paper link provided.

    Actually, I am more interested to know that whether such power consumption reduction can be achieved even for steam/vapour or not.
