Abstract

Abstract: This work provided a method for developing hydrate anti-agglomerant based on the analysis of active components of a plant extract with anti-agglomeration effect. The preliminary analysis on a plant-extract with anti-agglomeration performance demonstrated the active components mainly exist its ethyl acetate extraction section,which was proved to have the effect of preventing hydrate agglomeration by testing in a high pressure transparent sapphire cell. The Fourier Infrared Spectrometry(FTIR)and Gas Chromatography-Mass Spectrometry(GC-MS)were used to further analyze the functional group and molecular structure. Finally,a series of active materials were identified,most of which were plasticizer,emulsifier,stabilizer,and surfactant intermediate. The standard corresponding commercial materials were then purchased from commercial market and their effectiveness of preventing hydrate agglomeration was verified. Compared with the single material,the mixture of these materials performed better and could be directly used as an effective hydrate anti-agglomerant.

Key words: natural gas, hydrate, anti-agglomerant, plant extract

摘要： 针对深海三相混输中极易发生水合物堵塞及现有阻聚剂配方研制存在一定盲目性的问题，通过对有水合物防聚作用的一种植物提取液进行初步分析评价，确定其活性部位，借助傅里叶红外（FTIR）和气相色谱-质谱联用技术（GC-MS）对该活性部位进行官能团分析及物质鉴定，以分析出的物质复配高效、环保的水合物阻聚剂。在高压全透明蓝宝石反应釜中进行水合物防聚评价实验，发现此植物提取液的活性部位主要分布在它的乙酸乙酯相段中。而从该部位鉴定出的物质大多为增塑剂、乳化剂、稳定剂及表面活性剂制备原料之类的物质。通过购买相应市售标准品进行实验发现，各物质均具有部分水合物防聚效果，而它们的混合物水合物防聚效果更佳，可以直接作为一种有效、低廉、环保的水合物复配阻聚剂使用。
