    Good morning,
    is there any general procedure available for cleaning the coke compressor without stopping it? We have a new compressor with a manual system of naphta injection in each impeller.
    I would like to know any useful information to proceed, because it is the first time I am facing it.
    Thank you for your support,
    Marc

    Good day Marc,
    The coker wet gas compressors I have experience had naphtha injection via a nozzle in the suction pipe.
    A few things need to be checked before doing the operation. How long has the compressor been running? Has it loss efficiency? How much ? Is the piping clean ?
     
    Regards
    Claus

    Hello,
    sorry about the delay in answering your kind message.
    We have not seen a loss efficiency but we have experienced a slight increase in radial vibrations, so we would like to perform the washing in order to check if the impellers have debris on them.
    We have been running this compressor without washing since it was installed, which means more or less 1 year (8000 hours).
     
    Thank you in advance!
