Problems with the degradation of activated carbon in the pre-desulfurization tank
Thread Content
What methods are used to determine when the activated carbon in the pre-desulfurization tank has become ineffective, so that it can be removed?
The pressure difference in the pre-desulfurization tank: discharge is required when the pressure difference exceeds 0.2 Mp.
When the incoming H2S is the same as or very similar to the outgoing H2S, it can be determined that it has become ineffective! Isolate the system; it can be removed after pressure is released. Or it can be regenerated!
Based on the import and export pressure difference and the amount of hydrogen sulfide removed.
Observe the increase in H2S levels and pressure difference at the inlet and outlet
A small difference in the hydrogen sulfide content between imports and exports can indicate its failure. After cutting, pressure release and replacement allow for unloading.
The simplest and most direct method is to conduct an analysis of the sulfur content in the imports and exports; if the difference is not significant, it indicates that saturation has occurred and treatment is necessary
