Sulfur-containing wastewater: sulfides, ammonia nitrogen, oil content, phenols. Liquid ammonia: purity. Acidic gases: hydrogen sulfide concentration, hydrocarbons content, ammonia. Regeneration: Ammonia-rich liquid: hydrogen sulfide content, hydrocarbon content, oil content. Ammonia-poor liquid: hydrogen sulfide content, ammonia solution concentration. Acidic gases: hydrogen sulfide concentration, carbon dioxide, hydrocarbons content. Sulfur: Acidic gases: hydrogen sulfide concentration, hydrocarbon content. Inlet and outlet of the hydrogenation reactor: hydrogen content, total sulfur content. Outlet of the quench tower and absorption tower: hydrogen content, total sulfur content. Sulfur: purity. Temporarily added: It depends on the operating conditions; if judgment is uncertain, new analysis items and tasks can be added.
The sulfur recovery flue gas from stripping regeneration requires testing for hydrogen sulfide and ammonia levels. These two indicators directly affect the air distribution in the sulfur recovery furnace and the control of the furnace temperature
May I ask, how is ammonia measured, and what methods are used? Since ammonia in the process gas is highly soluble in water, the laboratory technicians reported that it was impossible to detect ammonia; please specify what method should be used
Liquid ammonia is used for product quality testing; I’m not sure what specific methods are employed
It’s not liquid ammonia; it’s the ammonia content in acidic gases!
Testing generally involves chemical analysis after absorption.
