Scorcher,
i am really intersted in the process of your plant, a bit strange to me, converting Sulfur to SO2,
can you tell me more about the products you extracted at the end of your process plant?
if you have any related information about the process overall, it would be highly beneficial...

in this site, you will find a good course about "Process Plant Start-Up and Construction", it deals with the project from managment point of view.
Regards,
To reduce the cooling in the air cooler, you can turn off some of the fan coolers. this will save some electric energy, and this is a usual practice in winter.
