Hi All,
At our large Ammonia Plant here on Site we have some Water Tube-shelled Oil Coolers on our Compressors that get absolutely jammed up full of calcium deposits to the stage where our Oil Temps go from a comfortable low 40s to up to the mid to there limit of 65 degrees C in a few days without much warning as we have limited capacity and time to keep cleaning them out which takes anything up to 4-5 hours per cooler on a 40 degree summer day isn't ideal either.
I was wondering if chemical treatment i.e. hydrochloric or an Acidic rinse would help to speed up the process if left soak first for an hour as some of the ports are so jammed up that rodding them is nearly impossible and tapping one in with a hammer is bad practice in case the pipe becomes fractured then your in all sorts of trouble.
