Question: During the preparation for commissioning of the (DMTO) olefin separation unit, what is the minimum pressure in the propylene distillation tower before liquid propylene is introduced into it? The pressure in the tower must not be lower than 0.6 MPa before liquid propylene is introduced, in order to prevent the liquid propylene from flashing due to low pressure, which could lead to a drop in temperature and damage to the equipment! Note: The answers will be announced automatically in two days!
18 kilograms. I’m not sure if it’s right? Avoid supercooling of propylene vaporization.
During the preparation for commissioning of the olefin separation unit, before introducing liquid propylene into the propylene distillation column, the pressure in the column must be at least 0.7 MPa
