Abstract Mercury in its elemental form is naturally present in most reservoir fluids. The presence of mercury can lead to serious operational and safety/health problems. Knowledge of the maximum solubility of elemental mercury with temperature and pressure in reservoir fluids is important to avoid mercury dropping out during processing operations, as mercury is naturally present in hydrocarbon deposits. In this work, a new experimental approach is presented to determine the mercury content in high pressure gas and liquid systems. Mercury solubility in methane, ethane, propane, nitrogen and carbon dioxide over a wide range of temperature and pressure (243.15–323.15K and up to 20 MPa) have been measured. An extensive literature review has been conducted on the solubilities of mercury in gases and liquid hydrocarbons. A critical evaluation of the literature data has been conducted to identify any inconsistencies in the reported data. The new experimental data generated in this work along with the literature data have been used to tune the binary interaction parameters of the Peng-Robinson and the Soave-Redlich-Kwong equations of state between mercury and the mentioned compounds.

高压流体中的元素汞分配第 1 部分：文献综述和单组分测量

摘要 汞以其元素形式天然存在于大多数储层流体中。汞的存在会导致严重的操作和安全/健康问题。了解元素汞在储层流体中随温度和压力的最大溶解度对于避免在加工操作过程中汞脱落很重要，因为汞天然存在于碳氢化合物沉积物中。在这项工作中，提出了一种新的实验方法来确定高压气体和液体系统中的汞含量。汞在甲烷、乙烷、丙烷、氮气和二氧化碳中的溶解度在很宽的温度和压力范围内（243.15-323.15K 和高达 20 兆帕）已被测量。对汞在气体和液态烃中的溶解度进行了广泛的文献综述。对文献数据进行了批判性评估，以确定报告数据中的任何不一致之处。在这项工作中产生的新实验数据与文献数据一起用于调整汞与上述化合物之间的 Peng-Robinson 和 Soave-Redlich-Kwong 状态方程的二元相互作用参数。
