I need to cool down my producer gas (composed of CO2, CO, CH4, H2, N2) from 2372F to 446F using water.Water inlet temp is at 77F and outlet at 120F.What method should I use to know the outlet temperature of the producer gas for every HE?Thanks in advance!What
The general rule is for the outlet temperature of the fluid being cooled to approach the inlet cooling medium by about 10 to 20 degrees. The usual way to do this is to try different size exchangers until you get to the economic limit in terms of cost for the exchangers. Most of the time you would try to use only one exchanger because that is typically the most cost effective. Also in the real world you typically have the outlet temperature of the fluid being cooled set by the process and you adjust your design to meet this requirement.
