Sudden increase in liquid level in the cyclic hydrogen desulfurization tower
Thread Content
The liquid level in the hydrocracking cycle hydrogen desulfurization tower has increased suddenly, while all other parameters are normal. What factors could cause this situation? ? ?
Analyze these aspects: high gas-phase load on the stripping column, tray blockage, false liquid level readings, and foaming of the amine solution!
The amount of lean liquid is too large, or the transfer of rich liquid is not smooth
