Quality of propylene product
Thread Content
Question: The C4 content in the propylene of the gas separation unit is now under control at the PPM level. What further actions can be taken to reduce it further? Do any of our other devices have the capability to control C4 indicators?
To further reduce the C4 content of propylene in the gas separation unit, optimizing the process flow and equipment operating parameters can be considered. Furthermore, it is necessary to check whether the separation technology currently in use is the most suitable for purifying propylene, for example by considering the use of more efficient distillation columns or improved adsorbents. At the same time, compare the strategies used in other devices to control C4, to see if there are any useful approaches, such as improving raw material treatment or trying new catalysts. .
