Publication date: Available online 14 December 2018Source: Chinese Journal of Chemical EngineeringAuthor(s): Chungang Xu, Xiaosen Li, Kefeng Yan, Xuke Ruan, Zhaoyang Chen, Zhiming XiaAbstractNatural gas hydrate (NGH) is considered as an alternative energy resouce in the future as it is proven to contain about 2 times carbon resouces of those contained in the fossil energy on Earth. Gas hydrate technology is a new technology which can be extensively used in methane production from NGH, gas separation and purification, gas transportation, sea-water desalination, pipeline safety and phase change energy storage, etc. Since the 1980s, the gas hydrate technology has become a research hotspot worldwide because of its relatively economic and environmental friendly characteristics. China is a big energy consuming country with coal as a dominant energy. With the development of the society, energy shortage and environmental pollution are becoming great obstacles to the prgress of the country. Therefore, in order to ensure the sustainable development of the society, it is of great significance to develop and utilize NGH and vigorously develop the gas hydrate technology. In this paper, the research advances in hydrate-based processes in China are compreshensively reviewed from different aspects, mainly including gas separation and purification, hydrate formation inhibition, sea-water desalination and methane exploitation from NGH by CH4-CO2 replacement. We are trying to show the relevant ...
