Need to find the heat exchange area, urgently
Thread Content
The desalinated water, which is at 70-80 degrees and a pressure of 0.85 MPA, needs to be cooled down to around 30 degrees. A heat exchanger is used for this cooling process, with circulating water being utilized; the temperature of this circulating water is 20-30 degrees and its pressure is 0.4 MPA. It is necessary to determine the heat exchange area, as well as which side of the heat exchanger should be fed with circulating water and which side should be fed with desalinated water

It is recommended to use the HTRI software for simulation calculations, or manual calculations can also be done using the methods outlined in chemical engineering design manuals, provided that the overall heat transfer coefficient is determined.

First of all, your maximum temperature is incorrect. Cool it down to 30°C; your inlet temperature will also be 30°C. Let’s restate the conditions~
Sorry, I’m a newcomer. I want to reduce the temperature of the deionized water from 70-80 degrees to around 30 degrees, while the temperature of the circulating water is 20-30 degrees. Make a small heat exchanger.
The desalinated water flows through the tube side, while the cooling water flows through the shell side. To determine the heat exchange area, it is necessary to know the hourly processing capacity of the desalinated water – in tons
Desalinated water at 70-80 degrees, pressure of 0.85 MPa? Is it steam condensate? Why isn’t waste heat recovered from demineralized water at such high temperatures and pressures? Using circulating water for cooling is such a waste
