Total Sulphur and Total Chlorides in Gas and Liquefied Petroleum Gas (LPG) Samples

Over the last decade, the importance of detecting sulphur and chlorides in gas and LPG products has increased dramatically. This is likely related to the necessity of complying with increasingly stringent government regulations, protecting expensive catalysts, and ensuring product quality. Reasons for detection and control of sulphur and chlorides in different process streams have existed for the last fifteen years, but detection limits have been reduced dramatically in recent times. For example, in order to protect expensive, sulphur-intolerant catalysts, the production feed for polypropylene or polyethylene must be monitored for sulphur and chloride content. The sulphur and chloride analyser used in this application must now have the ability to detect sulphur and chlorides from 1 parts per billion to 10 parts per million.
