Specifications for activated carbon used in the oil remover for PSA nitrogen production
Thread Content
Everyone, what are the specifications for the activated carbon used in the oil remover for PSA nitrogen production? We use 15#, but the specifications are unknown. The manufacturer also didn’t tell me, and they were evasive when I asked.
Generally, it is as follows: residual oil content: ≤0.003 mg/m3
Please be more specific; if we purchase it ourselves, how should we set the metrics?
I would like to ask how to maintain it? Or replace?
Under normal circumstances, the activated carbon is replaced once a year
What is it used to absorb? If it is intended for adsorbing oil and gas, the key parameters to consider are butane capacity, particle size, and CTC. For use in gas-phase adsorption, the benzene adsorption value is also important. The standard parameters for activated carbon include iodine value, specific surface area, particle size, density, moisture content, and ash content; manufacturers usually can provide these values. If they are unable to provide specific parameters, it’s very likely that the product used is of substandard quality or it is merely from an intermediary supplier
