In the soda ash production process, how much should the raw material CO2 hydrogen sulfide be controlled?

Everyone: I have just come into contact with soda ash production. How much should I control the raw material CO2 hydrogen sulfide? Is it necessary to refine and desulfurize?
Our company has an annual output of 110,000 tons and did not have a desulfurization device.
It should be determined based on the sulfate radical in the soda ash product. Since most of the current soda ash plants are carbon steel or cast iron equipment, the iron content in the mother liquor is correspondingly high, and the sulfur contained in the carbon dioxide can be used as an iron remover. Judging from the current soda ash companies, compared with the sulfate in raw salt, the sulfur of carbon dioxide accounts for a smaller proportion, and its content is not enough to affect product quality. If necessary, some alkali sulfide needs to be supplemented.
