Hydrogenated gasoline is alkaline in water solubility
Thread Content
This facility uses the Fushun OCT-MD process, with an annual production capacity of 300,000 tons. Recently, the raw material has been changed to DCC gasoline. Refined gasoline exhibits alkaline water solubility. It becomes neutral after a low score, but alkaline after stripping – what’s going on? Is it due to insufficient stripping or excessive stripping? The bottom temperature of the stripping tower should be controlled at 165°C, and the top pressure at 0.25 MPa. Please help!
Too much corrosion inhibitor was injected, I guess ~~~~
I agree with the opinion above; it is recommended to check the level of the reflux tank, measure the pH of the reflux stream, and also determine whether the medium in the reboiler is alkaline and whether there are any leaks
