Water flow issue in the desulfurization pre-cooling tower
Thread Content
I would like to ask everyone: it is known that the gas generation rate is 55,000 to 60,000 cubic meters per hour; the temperature of the gas entering the pre-cooling tower is 45°C, while the exit temperature of the gas is 30°C. How to calculate the cooling water flow rate? ? I’m not very familiar with the cooling water temperature; it’s maybe 25°C when it enters the tower and 35°C when it exits? Could everyone please tell this young guy how to calculate the cooling water flow rate? Thank you all first~
The rough calculation involves taking the specific heat of coke oven gas, multiplying it by the temperature difference to obtain the heat released by the coke oven gas; then dividing this value by the temperature difference for water to determine the amount of water needed. Finally, this amount is multiplied by a coefficient of 1.2 to 1.3, which gives the approximate amount of water required. The detailed calculation involves looking up the heat enthalpy of coke oven gas, and using this value to determine the exact amount of heat released by the coke oven gas. The temperature difference for water should be between 18°C and 23°C; low-temperature water generally has this temperature.
