“The WIM COMPAS ™ after our flare recovery system is the best way to control we don’t emit any unburned hydrocarbons and monitor compliance at the lowest costs”
WIM COMPAS ™– Versions
Continuous
This version is designed for top performance where response time, repeatability and reliability count. A small sample flow is mixed continuously with air. The air-fuel mixture undergoes catalytic combustion followed by measurement of the residual oxygen. This provides a direct measure of CARI and correlates to the Wobbe Index as per ASTM 4891-89. By integrating a specific gravity cell, heating value and air demand are also measurable.

The WIM COMPAS™ offers an unmatched, robust solution with high availability, for Fuel and flare gas combustion measuring, such as sour gas and flare gas. Hobré has developed an analyzer especially for these kinds of applications, that injects small amounts of gas into an air stream, typically at intervals of 30 seconds. The oxygen peak size is a direct measure of the air demand and proportional to the heating value (BTU).
High-temperature
WIM COMPAS High Temp analyzer
Keeping the gas above dewpoint is crucial to the success of most applications. The WIM Compas™ can be heated up to 55°C (131°F) as standard; high-temperature versions (up to 150°C / 300°F) are available if required
