In 1980, large air/liquid coolers were placed in a good number of new refineries in the Middle East because there was a lack of water. That was a disaster because it was poorly conceived. The idea was to use the air coolers when the air temperatures were an advantage. What wasn't considered was the impact of sand blasting the tubes 24/7 for 5 months. Then what to do when you end up with a cooler that looks like a shower head with hydrocarbons flying out. 

In the end, a sea water pipeline was added. The hot seawater then went to RO's and the permeate used for a variety of other uses thus taking advantage of the heat. The RO reject was sent to evap ponds.  They built a small greenhouse on one of the evap ponds. The moisture then condensed and was used for irrigation in the greenhouse. They grew Tomatoes and peppers. Pretty neat all done 39 years ago.
