Hello Everyone,
 
We use refinery gas as fuel at DCU furnaces. At the moment we have a problem of fouling in the fuel gas pipeline. It is a mixture of condensate, due to a problem with the separator, and probably corrosion products (black dust) that cause a partial obstruction. Has everybody have an experience with this problem? Some advise for cleanning the lines (carbon steal) during the next shotdown? I will apreciate your help?
 
Best regards
