How to calculate the temperature after heat exchange
Thread Content
The residue exchanges heat with crude oil: the residue flow rate is 40 T/h at a temperature of 190°C, while the crude oil flow rate is 130 T/h at 120°C. I would like to ask to what temperature can crude oil be heated through heat exchange?
Based on the requirement that the residue be cooled to a specified temperature, the temperature of the crude oil after heating is calculated using heat balance. Or, based on the temperature of the crude oil after heating, calculate the temperature of the residue after cooling. In any case, one of the temperatures for the residue oil or crude oil must be set first. .
This operating condition lacks an outlet temperature for the residue oil
