I want to reuse a heat exchanger to solve a plant problem by cooling a heavy hydricarbon with CW but I might have a problem with it.
Its design temperature is 149ºC (300ºF) and operating temperature of the hot fluid is 155ºC. With the pipe layout and length I was able to estimate a 5ºC temperature loss from the source to the HE inlet.
So, we are at the temperature operating limit but the design is not good. Since I don't have another suitable HE and to built a new one it will take some time... I had the idea of install a portion of finned tube from the source to the tie-in point of the line.
However I'm not able to calculate the heat/temperature loss of such a finned tube.
Where or how can I solve this equation. I'm not so familiar with finned tube thermal design. Is there any manual,good book o internet software that might help me?
