Hydrate promoter and preparation method thereof

一种水合物促进剂及其制备方法

Abstract

The invention belongs to the technical field of production promotion and utilization of gas hydrates, and particularly relates to a hydrate promoter and a preparation method thereof. The hydrate promoter is prepared by mixing cocamidopropyl betaine, dimethyl siloxane and a nonionic fluorinated surfactant which are used as additives with deionized water at the temperature ranging from 65 DEG C to 85 DEG C for 30-40 min; the solvent comprises, in percentage by mass, 3-7% of the cocamidopropyl betaine, 1.2-4.5% of the dimethyl siloxane, 0.2-1.5% of the nonionic fluorinated surfactant and the balance of the deionized water. The hydrate promoter can be widely applied to fields of gas hydrate storage and transportation technologies, gas hydrate separation technologies, sea water desalination and the like; the hydrate promoter is low in cost and low in consumption, hydrate generation conditions are reduced, time is shortened, the gas storage capacity is improved, and the economic benefit of hydrate production is effectively increased.
本发明属于气体水合物生产促进与利用技术领域,具体涉及一种水合物促进剂及其制备方法。所述水合物促进剂,由椰油酰胺丙基甜菜碱、二甲基硅氧烷、非离子氟表面活性剂作为添加剂与去离子水在65~85℃范围内搅拌30~40分钟制备而成;其中椰油酰胺丙基甜菜碱占溶剂的质量百分含量为3~7%;二甲基硅氧烷占溶剂的质量百分含量为1.2~4.5%;非离子氟表面活性剂占溶剂的质量百分含量为0.2~1.5%,其余为去离子水。本发明水合物促进剂可在气体水合物储运技术、气体水合物分离技术和海水淡化等领域得到广泛应用;并且成本低,用量少,使水合物生成的条件降低,时间缩短,储气量增大,有效地提高了水合物生产经济效益。
