水合物法的天然气提氦技术研究

氦气是发展国防军工和高科技产业不可或缺的战略性物资之一.由于氦气在自然界中的富集度很低,目前工业规模化提氦来源主要是含氦天然气.常用的提氦方法有吸附法、吸收法、低温冷凝法、膜分离法等,但它们都不能很好地解决提氦难度大、成本高、规模化工业应用水平较低等缺点.因此,引入水合分离技术,利用含氦天然气各组分生成水合物的条件差异在水合反应过程中对氦气提浓,同时辅以催化脱氢工艺,实现粗氦的精制.

Technology Research on Helium Abstraction from Natural Gas via Forming Hydrate

Helium gas was one of the indispensable and rare strategic materials for national defense military industry and highly technological industries.Owing to quite low enrichment degree of helium gas in the nature,the helium was mainly Abstracted from natural gas in the realm of industrial production currently.Processes like adsorption,absorption,low-temperature condensation,membrane separation,etc.were the ordinary methods for helium Abstraction.However,there were obvious difficulties in the Abstraction without...
