Problem of catalytic decomposition of gases
Thread Content
The propylene content in the gas composition we analyzed is 45% – is this an indication of over-fragmentation? The carbon value for liquefied gas is 0.56
What should be the normal level of propylene in the gas stream?
Is the resolved gas rich in carbon dioxide components? If it contains a high amount of propylene, could it be that the temperature at the bottom of the tower is too high, resulting in excessive resolution? It would be appropriate to lower this bottom temperature
It is normal for the C3 content in the gas being released to be high; generally, the gas coming from the top of the deethanizer does not consist entirely of C2 – C2 makes up only a small portion of it. However, if this gas is not released, it becomes difficult to control the pressure in the stabilizer downstream
