ABSTRACT:
In oil or chemical process equipment wherein process fluids under pressure are cooled by indirect heat exchange with cooling water which is subsequently recycled through a water cooling tower, leakage of process fluids into the cooling water is objectionable and potentially dangerous. A simple method for detecting such leaks and spotting the responsible heat exchange equipment consists of passing a sample stream of the cooling water, taken ahead of the cooling tower, through a testing vessel wherein the liquid flow is slowed sufficiently to permit entrained process fluids to separate while a constant water level is maintained in the testing vessel, and visually or instrumentally determining the presence and, if desired, the identity of contaminants separated in the testing vessel.
