SensoTech and the experts of the U.S. company HF Alkylation Consultants jointly developed an innovative solution for process monitoring: The LiquiSonic® 40 HF inline analyzer. The measuring system consists of two sensors and one controller. The sensors are installed directly into the existing main pipe of the alkylation unit and simultaneously measure in the process stream the hydrofluoric acid strength, the water content and the concentration of acid soluble oils.
The measurement accuracy is ± 0.05 wt% and the installation does not require a bypass. For the inline concentration measurement, a sonic velocity sensor and a density sensor are used, that are Ex-certified and made of corrosion resistant material.
