Problems with the hydrogenation of small-molecule polypropylene
Thread Content
For hydrogenation in small-scale production, what is the most suitable method? I would appreciate it if an expert could give some guidance
We use a pressure reducing valve to control the pressure in megapascals, but sometimes when the pressure reducing valve is inaccurate, we compare it with the pressure difference shown on the DCS display for judgment.
By using a hydrogen mass flow meter, it is possible to accurately measure the hydrogen flow rate, thereby enabling more precise control of MI. The hydrogen flow rate is controlled based on MI; experience can be gained through practice
