Analyzer for measuring hydrogen sulfide (H2S), moisture (H2O), carbon dioxide (CO2)
독특한 PA-TDL 기술이 적용된 TISOMIC은 최신 전자 기술을 사용하여 H2S, H2O 및 CO2에 대한 온라인 공정 분석기 (on-line process analyzer)입니다. TISOMIC의 일반적인 응용분야에는 multiphase crude oil의 H2S부터 판매 가스 및 파이프 라인 모니터링의 H2S, H2O 및 CO2까지 모두 포함됩니다.
Key benefits
- Close to zero maintenance
- No moving parts
- Stable and simple calibration
- Full separation of photo acoustic measuring cell and electronics
- Detection range from low ppm to percentage levels
- No limitations in natural gas matrix
- Simultaneous multi-stream measurement of hydrogen sulfide (H2S), moisture (H2O), carbon dioxide (CO2) possible
- Analyzer cell flow of ±200 sccm/min
“We have veritually no maintenance on the TISOMIC analyser, further it has a very small measuring cell and therefor hardly any gas emission. The analyser measures for us both low H2S, H2O, and CO2 content”
PA-TDL Technology
The TISOMIC with PA-TDL technology, Measuring the Photo Acoustic effect excited by a Tunable Diode Laser (TDL), can simultaneously measure hydrogen sulfide (H2S), moisture ( H2O), carbon dioxide (CO2) in liquid and gas streams. Our PA-TDL technology consists of a high-quality microphone for detecting the Photo Acoustic resonance created by a tunable diode laser in the measuring cell. Analyzing in the low ppm range is achievable by using a resonator with a 10 centimeter path length, without the use of moving parts and multi-pass mirrors.The product features include:
- Low, less-than-200cc/min cell flow
- Wide range over four decades (log scale)
- Temperature controlled cell
- Full separation of sample-wetted parts and electronics by using fiber optics
When the TISOMIC is used with a well-designed sample conditioning system, such as the Hobré HIFISC, it can run with a drift of typically less than 3% over a year. Automatic validation or manual calibration is required only once every few months. Designed to be low maintenance, with power as its only utility, the cost of ownership is the lowest on the market.
