Abstract:
This project is focused on Repsol's one cell cooling tower, also named 417-E-203. The temperature gap of the cooling tower is 15ºC by design, however, it currently works with a temperature gap of 6-7ºC. The lack of water in some equipment, has motivated the need to identify the facilities that need to be cleaned or replaced. Two ways for improving water savings are studied: (i) implementing an Aspen HYSYS simulation of the overall cooling water circuit and find the bottleneck equipment, and (ii) studying the effect of the increase of cycles of concentration of the cooling tower.
