  3. ASU Sample Stream – Typical Measurements

  4. Argon Extraction In Cryogenic ASU • Ar draw off point traditionally based on a percentage O2 measurement • Indirect measurement with limited resolution • Crude Ar yield compromised so that safe operation can be guaranteed. Argon Purifier

  5. Description of Process • To optimize process for argon extraction, the draw-off O2/Ar from O2 LP column can be tuned to keep N2 < 2000ppm with measurement of N2 in Crude Ar • If column concentration profile too low, high N2 produced • - N2 can block condenser of crude Ar column eliminating reflux • - Causes a drop in Ar and O2 concentrations in LP column • - Production is lost and can take hours to restart process • If column concentration profile is too high, high O2 produced • - loss of Ar in waste N2 • - excess O2 enters crude Ar column

  6. Solution • SERVOPRO Chroma (K4000) to measure N2 in Crude Ar with Plasma Emission Detector • SERVOPRO Chroma (K4000) with H-Cut Injection and O2 Trap permits interence free measurement of N2 in Ar with up to 90% O2 present • Provides tighter process control than O2 measurement allowing a higher concentration of Ar taken from LP column without compromising process or damaging Crude Ar Column

  7. SERVOPRO Chroma Trace Gas Analyser • Gas Chromatograph (GC) technology • Configurable for the sub ppm analysis of N2 in Crude Ar • Multipoint analysis provides valuable continuous data from across the separation process • Each peak reported on screen with a process value (i.e. percentage, ppm or ppb).

  8. SERVOPRO Chroma Trace Gas Analyser • Chroma configured for the sub ppm analysis of N2 in Crude Ar • Measurement unobtainable by Trace N2 in Ar analysers due to O2 interference…. • Or thermal conductivity detectors due to low level sensitivity requirement SERVOPRO Chroma Trace N2 MultiExact % O2

  9. Typical LP Column Concentration Profile Servomex Gas Analysis Solutions for Cryogenic ASU Recovery can be worth hundreds of thousands of dollars a year Increase yield between 3-5%

  10. Real Results: Cryogenic ASU with 1700 m3/H capacity Servomex Gas Analysis Solutions for Cryogenic ASU • Average output of argon product pre-Chroma: 1700m3/H • Control by Oxygen Analysis • N2in Ar side column feed measured by the Trace N2 Analyser at 500ppm N2 at draw-off point. • Average output of argon product post-Chroma: 1750m3/H • Argon yield increase circa. 3%.

  11. Typical Payback & Return on Investment Plant Operation Variables Return on Investment & Payback Results

  12. Summary: ASU Optimization for Argon Extraction • Challenge • Most plants run inefficiently in order to run safely as they do not have effective means to monitor N2 level in draw-off from O2 LP column • Solution • SERVOPRO Chroma (k4000) configured to measure trace N2 in Ar and O2 • 0-200ppm, 0-2000ppm • Argon recovery can be improved by up to 5% • Payback < 1 year

  13. Servomex Innovation - Ambient Oxygen Gas Detection • Ambient monitoring in • ASU’s • Bottling Plants • Laboratories • Non-depleting and highly stable measurement technology • No sensor replacement • Noshelf life issues • longcalibration intervals. • No false alarms, Increased Safety • Servomex paramagnetic technology • paracube®microsensor never needs replacing • saving $400 a year / per Oxygen Point • Electrochemical sensor replacement costs per year • Reduced maintenance • No loss of reliability means no false alarms • potentially saving $10,000 or more a year • False alarm evacuations per year, lost time and production JUST LAUNCHED
