An important activity in the optimization of the HF alkylation process is the analysis of re-circulating acid.
This is normally achieved by taking off-line samples and conducting laboratory analyses on a periodic basis. There are, however, a number of problems associated with this approach.
The ABB HF Alkylation Process Acid Analyzer is an FT-NIR based process analyzer that offers a reliable solution to the problems faced by HF alkylation operators.
This is achieved by the on-line analysis of the circulating acid stream every 2 minutes, providing accurate catalyst composition in terms of HF, ASO and water content. This improves personnel safety, process control, and corrosion monitoring and catalyst efficiency.
A reliable, fast, on-line measurement method for HF acid has long been sought after by operators of these units.
