What is the flow velocity of normal gas evaporation inside an intermittent distillation column?
Thread Content
Recently, while operating a tower, excessive evaporation and a rapid evaporation rate led the tower to approach the point of flooding, which caused the reformed product to rise upward and resulted in substandard output； May I ask what the gas flow velocity inside a conventional intermittent structured packing distillation column is? ? ?
Where is the mistake in the following calculation? Given a reflux ratio of 5:1, an output volume of a, a reflux volume of 5a, the density of the material as p, and a molecular weight of 84 g/mol; calculate the gas flow velocity inside the tower? Total evaporation amount = a + 5a = 6a; this value is then converted into the gas volume per unit time under standard conditions, and after that, it is divided by the cross-sectional area of the tower and its porosity to determine the gas velocity inside the tower
Taking that into account, what value should this coefficient take? Should it be 0.5? ? ? ?
Send me the detailed information on your tower, including the operating conditions and the substances
Select the two values with the largest gas volume and the largest liquid volume to calculate the tower diameter. Simulate the calculation first.
