The KECO Model 205 PermaStream H₂S in Liquids Process Analyzer offers an accurate quantification of hydrogen sulfide (H₂S) in sample streams of crude oil as part of environmental compliance, safety and quality control practices. The inline analyzer measures H₂S in light/medium/heavy crude oil, dirty/clean water, diesel, fuel oil and drilling fluid in real time. By providing accurate and continuous monitoring of H2S levels in liquid streams, the analyzer helps companies demonstrate compliance with air permits promoting the reduction of environmental impacts.

Naturally found in crude oil, H₂S can pose a threat when inhaled due to its toxicity. Its corrosive properties also can cause damage to storage tanks and pipelines used to transport crude oil. In addition, crude oil with lower levels of H₂S is more valuable as it can be more readily processed into petroleum products.

Accurate quantification of H₂S is necessary for its efficient removal from crude oil. Due to its opacity and complex structure, it cannot be visually measured. The most effective measurement method requires stripping H₂S from the liquid into gas for analysis by an analyzer or a sensor. The Model 205 PermaStream H₂S in Liquids Process Analyzer efficiently and reliably separates H₂S from the liquid sample for measurement in the gas phase without false positives as it only detects H₂S.

A simple device, the 205 PermaStream continuously provides an ultra-clean and dry sample to the H₂S sensor for real-time and accurate measurement. Dependable in operation, the analyzer requires no field calibration, sample conditioning, filters nor pumps. Incorporating KECO Membrane Technology, the ultra-low-maintenance device addresses the shortfalls of headspace stripping columns traditionally used for this purpose that were problematic because of oil clumping and high maintenance associated with replacing a multitude of parts that break down over time. 

The 205 PermaStream measures the presence of H₂S in ppm or even percent ranges in complex liquid streams. Set in line at process and flow, the H₂S liquid process analyzer supports continuous online monitoring of H₂S.
