My first process audit was to identify the problem areas in a cooling tower in phaosphoric acid plant. In this plant the cooling water was used for direct process cooling i.e. it was coming in contact with process gases for their cooling. So the pH of CW was very low at ~1-2. This was causing many problems in terms of failure of mechanical components leading to vibration problems & vary high approach of 11°C compared to design value of 3.9°C.
This report shows how can you attack on a problem for troubleshooting going in sequncial steps one by one. I used my cooling tower model which is already available on this blog here & found a very good match of design data. Then I simulated the factor affecting the performance of cooling tower one by one. The impact of each factor led to finally the same approach of ~10°C, which indicates the accuracy of evaluation.
