Dithiazine is a compound formed after passage of natural gas or renewable natural gas containing hydrogen sulfide through amine based hydrogen sulfide liquid scavenger towers. Similar to elemental sulfur, dithiazine can solidify at pressure or temperature reduction points and result in potential equipment issues. This study summarizes the state of monitoring dithiazine in gaseous fuels and assesses the potential for selected gas analyzers to continuously monitor dithiazine on-line or be developed for this application.
