I'am looking for a unit or system to control the temperature of the condensor. The streams that are available are the following:
- cooling water at ambient temperature
- chilled water at 5-7°C
- Steam at 3-4 bar

Is it possible to use these streams (one or more) to create a system to use water of 85°C at one moment and perhaps some hours later water of 40°C and followed by perhaps 60°C, 20°C....
The water will be used to control the condensor temperature during reaction times with the possibility to set a setpunt of the water used for heat exchange with the product side in a shell and tube heat exchanger.

echnat0n:

I do not understand clearly what you are proposing to do. You do not give us basic data:

• A detailed sketch of the system;
• The vapor composition being condensed;
• The type and configuration of the condenser being used;
• The detailed reason why you want to employ different fluids to “create” a cooling system. You should explain what are your goals and how you justify mixing/creating cooling water of different temperatures.

I understand that you have a reactor that produces a vapor overhead product. You are condensing this overhead vapor. I also have to presume that you are MERELY CONDENSING the overhead product – not subcooling it. If that is the case, why are you concerned with the cooling medium being at different temperatures? As long as you are able to drop out the saturated condensate, there should be no problem. Please explain.
