Heat balance of desulfurization tower
Thread Content
It is known that the volume of semi-water gas entering the desulfurization tower is 23,340 m3/h; the temperature of the solution entering the tower is 36°C, while the temperature of the solution exiting the tower is 35°C. The temperature of the semi-water gas entering the tower is 27°C, and its temperature after leaving the tower is 31.32°C. The pressure of the semi-water gas entering the tower is 0.049 MPa. I would like to ask how to perform a heat balance calculation. Thank you! ! ! ! ! ! :victory:
The purpose of heat balance is to determine the parameters of a certain material； Based on the conditions provided by the poster, the only parameter that is definitely missing in this system is the flow rate of the desulfurization fluid. Objectively speaking, the flow rate of this fluid needs to be determined through material balance calculations based on the sulfur capacity ； Material balance is typically used to determine the flow rate of heating or cooling media; it has limited utility in other aspects. Heat balance cannot solve all problems.
This condition doesn’t provide everything; you also need to know your desulfurization efficiency (before and after sulfur removal), as well as the composition of various components in the gas, in order to calculate the average atomic weight, average specific heat, etc. The heat generated by the temperature rise of the gas is equal to the heat of water
