Effect of the stripping tower top pressure on the stripping efficiency
Thread Content
A high pressure at the top of the stripping tower facilitates full contact between the two phases inside the tower; does this improve the efficiency of stripping? Is a lower pressure still better, as it facilitates the extraction of the components and leads to better results?
Does stripping rely on stripping steam to reduce the vapor pressure of the oil and gas, thereby causing the light components to flash out? Where does two-phase exchange come from?
Adjusted according to the solubility of the gaseous phase and solution under different pressure conditions
With low tower top pressure, it is easier for the light components to move upward.
The stripping tower is primarily used to remove the light components from the liquid phase, so that the product obtained from the bottom of the tower meets the required standards. The gas phase that is removed will certainly carry some of the heavier components along with it; as long as the product from the bottom of the tower is of satisfactory quality and both the tower pressure and the temperature at the top of the tower are within the specified ranges, everything is fine
Reduced pressure is beneficial for stripping, but this is not absolute; in the case of chemical reactions, the decomposition temperature and vapor pressure also play a role. Only through optimization and tuning can this be determined
