Regarding the calculation of gas-liquid ratio
Thread Content
There is a project involving the design of a spray tower with a height of 6.5 meters. Water is sprayed from a height of 4 meters. The type of waste gas is DMF, with an inlet concentration of 500 and an outlet concentration of 200. I would appreciate it if experts could tell me what the gas-liquid ratio is, what kind of water pump should be used, and how exactly the gas-liquid ratio is calculated. Thank you all
If doing the calculation manually, it is first necessary to know the temperature in order to determine how much DMF is carried away by the circulating spray water (the equilibrium concentration of DMF in the water exiting the spray tower). The gas-liquid ratio can be calculated using the material balance of the absorber; however, this method is only for estimation purposes. For an accurate calculation, it’s best to use Aspen for simulation
The gas-liquid ratio should be the responsibility of the design institute, right?；
