Hello everyone, how is the hourly flow rate calculated when using the HDF method for gas desulfurization?

Is it the HPF method for desulfurization? I’ve never heard of the HDF method! ! ! Taking 1 million tons of coking as an example, the treatment capacity of the gas purification system is approximately 50,000 m3 per hour. The HPF method for desulfurization uses ammonia in the gas as a base source, and under the action of the HPF catalyst, it decomposes H2S and HCN present in the gas. The entire reaction can be divided into four stages: absorption reaction, catalytic chemical reaction, catalytic regeneration reaction, and side reactions. H2S and NH3 in the gas react in an aqueous solution to form NH4HS and (NH4)2S; under the action of the HPF catalyst, (NH4)2Sx is formed, and finally S and Sx are produced through oxidation regeneration. CO2 in the gas reacts with NH3 in an aqueous solution to form NH4HCO2 and (NH4)2CO3, which provide a base source for the solution. The main components of the HPF catalyst are PDS, hydroquinone, and FeSO4; among these, PDS serves as the primary catalyst, hydroquinone acts as a co-catalyst, and FeSO4 functions to promote flocculation. These components must be mixed in the correct proportions in order to improve the fluidity of the desulfurization solution and prevent blockages in the desulfurization tower

Hello, may I ask about the hourly flow rate of the desulfurization liquid?

The specific formulas for these can be found in the “Coking Design References” or the “Gas Design Manual”. 1 million tons of coking: the amount of dry coal is calculated based on a coking rate of 76%, while the volume of gas produced is calculated based on 345 Nm3 per ton of dry coal. The sulfur production is calculated based on the desulfurization efficiency, while the sulfur capacity and the circulation volume of the desulfurization liquid are determined based on the desulfurizing agent; all the specific parameters can be found in the manual. The book can be downloaded on this forum.
