- 为探究位阻胺脱硫溶剂在天然气净化过程中面对油类、盐类及固体颗粒杂质时的发泡特性,评估抗发泡性能，进行位阻胺脱硫溶剂在天然气净化厂的工业应用实验。通过模拟污染条件,采用氮气流量400 mL/min、水浴温度40 ℃的发泡装置,向位阻胺脱硫溶剂中添加不同比例的气田水、不同浓度及粒径的颗粒杂质(如FeS和活性炭),并记录泡沫高度与消泡时间。位阻胺脱硫溶剂在面对含油气田水和大颗粒杂质时,表现出优异的抗发泡性能,泡沫高度基本＜5 cm,消泡时间远＜5 s,显著优于传统对比剂溶剂。位阻胺脱硫溶剂通过多种机制显著提升了胺液抗发泡性能,工业应用试验进一步验证了位阻胺脱硫溶剂的长期抗发泡性能。位阻胺脱硫溶剂的抗发泡性能可有效减少天然气净化过程中的发泡问题,提升生产效率,为工业应用提供有力支持。
This study investigates the foaming properties of sterically hindered amine desulfurization solvent in natural gas purification processes when exposed to oil, salts, and solid particulate impurities, aiming to assess their antifoaming performance and conducted industrial application experiment of sterically hindered amine desulfurization solvent in natural gas purification plants. By simulating polluted conditions, a foaming experiment device with a nitrogen flow rate of 400 mL/min and a water bath temperature of 40 ℃ was used. Various proportions of produced water from gas fields, as well as particulate impurities of different concentrations and sizes(such as ferrous sulfide and activated carbon), were added to the sterically hindered amine desulfurization solvent. The foam height and defoaming time were measured and recorded. When exposed to oil-containing produced water and large particulate impurities, the sterically hindered amine solution showed excellent antifoaming performance, with foam heights consistently below 5 cm and defoaming times significantly less than 5 seconds, outperforming traditional reference solvents. The sterically hindered amine desulfurization solvents significantly enhance the antifoaming properties of amine solutions through multiple mechanisms. Industrial application trials further verified the long-term antifoaming performance of the sterically hindered amine desulfurization solvent. The superior antifoaming capability of the sterically hindered amine desulfurization solvent effectively mitigates foaming issues during natural gas purification, thereby improving production efficiency and providing strong support for its industrial application.
