The ACA.HF Analyzer: The new standard in safety, simplicity, and accuracy for analyzing HF catalyst

November 22, 2011

Hydrofluoric acid is a common catalyst used in petroleum processing, and accurate analysis of how much HF is re-circulating within the process contributes significantly to maximizing the yield rate of crude stock. Early approaches to HF monitoring involved taking manual samples and analyzing them in a laboratory, however that sample approach offers limited accuracy and exposes lab workers to toxins. More recent FTNIR techniques are very accurate, but adaptation for real-time online monitoring is complex and costly. A global refining company and Invensys Operations Management have now teamed up to validate new online HF monitoring models that deliver highly reliable results at significantly lower acquisition and operating costs.
