How much methanol vapor can be flashed out from 5 kilograms of pure methanol at atmospheric pressure?
Thread Content
How much methanol vapor can flash off when refined methanol at 0.5 MPa is reduced to atmospheric pressure? How is this calculated? What is the formula?
In the case of triple-column distillation, the amount taken from the main column is related to the methanol content in the feed as well as the distribution of the outputs from each column; a ratio of 4 to 6 has been mentioned for reference
It’s a bit off-topic – could you please explain what process is involved in using the steam generated by the atmospheric flash evaporation of 0.5 kilograms of pure methanol?
It depends on what the temperature of the pure methanol is at 0.5 MPa
Simply put, according to the formula pv=nrt, if the temperature remains constant and the pressure is reduced to one kilogram, which is one-fifth of the original value, the volume will increase by a factor of five.
