本程序由四部分组成，用于对液态氟化氢（HF）流进行取样，并分析这些流的酸度、水含量和酸溶性油。本方法适用于新鲜酸和烷基化工艺系统酸。酸溶性油测定也适用于再生器底部样品。然而，再生器底部样品的酸度和水分测定必须分别按照UOP方法379和382进行。附录提供了有关在线仪器选项的信息，该选项可以显著减少带入实验室进行分析的样本数量。

This 4-part procedure is for the sampling of liquid hydrogen fluoride (HF) streams and the analysis of these streams for acidity, water content and acid-soluble oil. The method is applicable to fresh acid and alkylation process system acid. The acid-soluble oil determination is also applicable to regenerator bottoms samples. However, acidity and water determinations on regenerator bottoms samples must be conducted according to UOP Methods 379 and 382, respectively. The Appendix provides information about an online instrumental option that could significantly reduce the number of samples that are brought into the lab for analysis.
