Thermal nitrogen desulfurization has achieved remarkable results at Qilu Petrochemical, enabling the removal of SO2
I guess Qianqian can’t take it! ~A consumption of several thousand cubic meters of nitrogen per hour is quite costly!
Could you send me the PID diagram? How to achieve the recycling of nitrogen and hydrogen!
Isn’t a blower used for circulation during the presulfurization of exhaust gas hydrogenation catalysts? Is nitrogen circulation also carried out using this same process?
I see – it’s about adding a pipeline from the induced draft fan to the CLAUS furnace side!
I would like to ask: How should ferrous sulfide accumulated in the catalyst bed or the process gas pipelines be dealt with using hot nitrogen purging?
When the CLAUS furnace is in a normal combustion state, micro-peroxide can be used to treat ferrous sulfide at the end of sulfur removal!
