Field of application
The JT33 gas analyzer offers continuous, real-time H2S measurement with low maintenance requirements. It enables plant operators and owners to meet gas quality standards, improve process control, and ensure asset integrity. Using proven differential technology, the JT33 tolerates stream changes while meeting measurement performance specifications. It also features auto-validation and advanced diagnostics supported by Heartbeat Technology for verification reporting.
Natural gas, biomethane, and carbon dioxide pipelines: prevent corrosion and minimize the risk of an uncontrollable event, ensuring asset integrity
Natural gas and LNG plants: optimize gas sweetening processes (amine, solid scavengers, and others)
NGL, refining, and petrochemical gas streams: assure gas quality and asset protection in fractionization, refining, and stream cracking processes
Carbon capture processes (CCUS): monitor processes and ensure that CO2 meets quality specifications
Benefits
Continuous, real-time TDLAS measurements with proven metrology to meet measurement specifications
Robust patented differential technology which tolerates contaminants and stream changes in tough applications
