After we use a plate heat exchanger for quite some time, let say a year for instance, you can expect some fouling on the heat exchanger plate oil side. The steam side might not be as dirty as the oil side. When fouling is form on the surface of the heat exchanger, the heat transfer is no longer efective. If you calculate the overall heat transfer coeffecient, the value will be lower compared to when you first commision the same heat exchanger. Therefore some cleaning is neccesary. Just choose either by dismantling the heat exchanger or do some "Cleaning In Progress" (CIP) using de-carbonizer or hot caustic.The photo which i picked from my friends blog is a clear example of bad fouling taking place on a plate heat exchanger oil side. Have you seen something like this before?
