HF Monitoring and Detection

TAS is the expert in designing, integrating and maintaining hydrogen fluoride detection systems. Boasting over thirty open path hydrogen fluoride (HF) detection systems currently in use, TAS has the expertise, credentials, and understanding required to monitor even the toughest gas monitoring challenges.

Considerations for HF Detection and Monitoring Systems

When anhydrous or highly concentrated hydrogen fluoride is released into the atmosphere, it forms a very dense plume. This is the result of a number of chemical interactions including reactions with water and agglomeration of hydrogen fluoride molecules into semi-stable oligomers or droplets. Often this results in released hydrogen fluoride plumes behaving as a dense gas. They will move as if heavier than air, sloughing toward the ground. However, the hydrogen fluoride molecule is lighter than air. As hydrogen fluoride agglomerates or droplets break apart the hydrogen fluoride gas behaves as a lighter than air gas and begins to loft.

Highly dense plumes of any type can block open path optical sensors. The density of a hydrogen fluoride plume depends on the concentration of the release and the atmospheric properties at the time of release (temperature, humidity, wind speed, turbulence). Conditions of hydrogen fluoride releases require advanced knowledge of the behavior of the plumes and the phases of plumes within the varied geometric spaces of an industrial environment.

Ongoing Support

TAS can be as involved or completely removed as necessary once your system is installed. We can provide training and complete handoff, or we can visit your site for regular preventative maintenance checks, usually once a year, and even occasionally provide free data analysis. Customer satisfaction is the lifeblood of our success.
