Kinetic promotion of mixed methane-THF hydrate by additives: Opportune to energy storage

Abstract

Natural gas storage in the form of clathrate hydrates (Solidified natural gas; SNG) is an innovative and an extremely safe approach. Application of environmentally benign additives to enhance the hydrate formation kinetics is highly promising and possesses significant research potential. In this work, we elucidate the influence of hydrophilic/hydrophobic eco-friendly additives on the kinetics of mixed methane-tetrahydrofuran hydrates along with morphological observation. Further, the mixed methane-THF hydrates formed were characterized employing a high-pressure micro-differential scanning calorimetry (µ-DSC). Enhanced kinetics and microscale analysis in presence of these additives present salient information to aid the commercial deployment of SNG technology. © 2019 The Authors. Published by Elsevier Ltd.
