Unlock Real-Time Fuel Gas Insight: Eliminate Combustion Risks and Compliance Surprises
Maintaining consistent fuel gas quality is critical for efficient combustion, emissions control and protecting downstream equipment. However, operators often face difficulties in real-time monitoring of fuel gas composition and sulfur content. Incomplete or delayed data can lead to suboptimal combustion, unexpected process upsets, and costly compliance violations due to excess sulfur emissions. When real-time insight is missing or delayed, operators face a cascade of consequences:
Hidden Composition Swings
Fuel gas streams often fluctuate in methane content, inert gases, and trace contaminants. Without continuous, on-line analysis, these swings go unnoticed until combustion performance deteriorates—resulting in flame instability, reduced thermal efficiency, and increased unburned hydrocarbons.
Sulfur Surprises
Even small spikes in sulfur can poison catalysts, corrode piping, and trigger environmental excursions. Relying on periodic grab samples means you’re always reacting to yesterday’s data, not today’s reality.
