摘要: Method for treating a heat exchanger which in operation is used to cool process water which has been in contact with polymer particles. The method includes passing to the process side of the heat exchanger a treatment stream while the heat exchanger is at an elevated temperature compared to the temperature when the heat exchanger is in operation.
