How to calculate the sulfur capacity for deep desulfurization
Thread Content
How can the replacement time of desulfurization agents be determined based on their sulfur capacity? How is the sulfur capacity of high-purity desulfurization agents calculated? We use T103 and T504 desulfurizers; the COS level is around 700 mg/m3, with no H2S present. The gas flow rate is 7500 M3/H.
The theoretical sulfur capacity is provided by the manufacturer; it represents the maximum amount of sulfur that the desulfurizer can adsorb. It is usually expressed as the mass of sulfur adsorbed per unit mass of desulfurizer, in percent form (note whether it is based on sulfur, hydrogen sulfide, or sulfur dioxide). The actual sulfur capacity refers to the mass of sulfur adsorbed per unit mass of desulfurizer, and its calculation formula is: gas volume * sulfur content * operating time
The sulfur capacity is merely a conceptual value; ultimately, it is the composition of the exhaust gas and costs that determine the timing for replacing the desulfurization agent as well as the manufacturer to be used
