Increase the sulfur-to-air ratio
Thread Content
I read in the materials that increasing the air-to-gas ratio in the sulfur production furnace means increasing the air volume supplied to that furnace. Is that correct? Why does increasing the gas-air specific energy improve the sulfur conversion rate? Thank you, extra points; everyone is welcome to discuss
An appropriate air-to-gas ratio is an important factor in improving conversion rate
Personal understanding: The air-to-gas ratio is calculated based on the concentration of hydrogen sulfide, the acidic gas. A high air-to-gas ratio corresponds to a high hydrogen sulfide concentration; with a higher concentration of hydrogen sulfide in the acidic gases, the sulfur conversion rate is certainly higher than when the hydrogen sulfide concentration is lower.
This is not entirely correct; to achieve the highest conversion rate, it is necessary to ensure that the gas-to-air ratio is 2 when the acidic gases are burned, such that H2S/SO2=2. In the case of hydrogenation-reduction absorption systems, the gas flow rate must be kept so that H2S/SO2 is slightly greater than 2, as either too high or too low a gas-to-air ratio will not result in an increased conversion rate.
