WIM COMPAS™ F – Fuel gas & flare gas combustion measuring

The WIM COMPAS™ F adds to Hobré’s portfolio of process analyzers for (Fuel and flare gas combustion measuring) measuring the Wobbe Index, heating value (BTU) and the Combustion Air Requirement Index (CARI). Designed and manufactured in-house, the WIM COMPAS™ F builds on hobré’s 20+ years of success and experience with residual oxygen type analyzers. The WIM Compas™ F is used to control the thermal input and air:fuel ratio in such a way that disturbances caused by fuel gas quality fluctuations are minimized, the combustion process occurs with maximum efficiency and emissions are reduced to a minimum.

THE 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.

Cyclic injection

The WIM COMPAS™ F 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

Keeping the gas above dewpoint is crucial to the success of most applications. The WIM Compas™ F can be heated up to 55°C (131°F) as standard; high-temperature versions (up to 150°C / 300°F) are available if required.
