Clora® Online Analyzer

Online Chlorine Analysis in Hydrocarbon or Water

Chlorine is often present in crude oils and the concentration can vary greatly depending on the origin. If not removed, Chlorine can react to form highly corrosive hydrochloric acid in areas such as crude tower overheads, leading to serious operational issues, economic loss, and safety concerns. The need for a reliable online chlorine analyzer for refining process control is more important than ever. Clora Online utilizes ASTM D7536 technology and delivers continuous chlorine analysis to monitor plant equipment corrosion. By monitoring desalted crude, a plant can optimize performance and immediately see impacts of crude changes (including organic chloride). Additionally, monitoring overhead water can provide the necessary feedback for chemical feed.

Methods: ASTM D7536

Features

Clora Online provides chlorine analysis without consumable gasses or elevated temperature processes and delivers real-time data with a dynamic range of 0.2 to 3,000 ppm wt%. Measurement time is typically 5 minutes; however, 15-second snapshot data is available to monitor process upsets.

  • Continuous and real-time analysis
  • Extremely low maintenance
  • Total chlorine analysis
  • For use in multiple application areas
  • Monitor corrosion & increase productivity
