    • A method for characterizing and optimizing refinery feedstock blends according to their corrosivity is provided. Refinery feedstocks can be characterized based on any of: dissociation of acids in the crude, breakup of naphthenic acid molecular associations, mass changes of carbon steel samples, and/or dissociation of sulfur compounds in the feedstocks. The characterization is performed as a function of temperature via any of electrical resistivity measurement, vibrational spectroscopic analysis, voltammetry, electrochemical impedance spectroscopy, crystal microbalance measurements of weight changes, and combinations thereof. The method employs models and/or hardware to optimize the usage of refinery feedstocks in the blending and valuation of the feedstocks.
    • 提供了一种根据其腐蚀性来表征和优化炼油原料混合物的方法。 精炼原料可以基于以下任何一种来表征:粗品中的酸解离,环烷酸分子缔合的分解,碳钢样品的质量变化和/或原料中硫化合物的解离。 通过电阻率测量,振动光谱分析,伏安法,电化学阻抗谱,重量变化的晶体微量天平测量及其组合中的任何一种来进行表征作为温度的函数。 该方法采用模型和/或硬件来优化炼油原料在原料的混合和估价中的使用。
