Can someone advise the method of sulphur recovery in a Performance test of sulphur recovery unit (SRU) in the sense whether % sulphur recovery can be measured by
Sulphur in feed X 100/product sulphur received in sulphur storage? There are some people who believe that sulphur recovery can be estimated by measuring the sulphur in feed (A) and sulphur species in the incinerator stack (B) and simple subtraction of (A)-(B). However I strongly believe that the sulphur balance of the whole plant should be done which includes quantity of sulphur received in storage pit. Please advise. I would be grateful if somebody advises various methods with pros and cons of each and finally the best method practiced in the industry.
