Calculate yield from online analyzer analysis results
Thread Content
I have just installed an online analyzer for hydrogen sulfide and sulfur dioxide, and it is located behind the exhaust gas liquid separation tank. SO2 and H2S together account for about 1 percent, so what can be the recovery rate? 97% is about right, right? The exhaust gas absorption part is another matter~
It seems that the operation of your device is quite stable. Under normal circumstances, the unit operates well, with the combined level of SO2 and H2S at around one percent. At this point, the conversion rate is around 97%.
By using the exhaust gas concentration and comparing it with the concentration of the feed acid gas, the reaction conversion rate of the acid gas can be calculated; this represents the sulfur recovery rate. If the exhaust gas concentration is 1% of the feed acid gas concentration, then the recovery rate should be greater than 97%, around 99% to be precise
I don’t understand why the people mentioned above are so certain; at least the H2S concentration in the feed gas should be checked in order to make a more accurate estimation.
The recovery rate should be calculated based on the ratio of the total sulfur compound content at the back of the exhaust gas liquid separation tank to the total sulfur-containing compound content before the sulfur production furnace.
