Comments On 'effect Of Promoter On Gas Hydrate Formation And Dissociation' By Ajay Mandal And Sukumar Laik

摘要

In their paper recently published in this journal, Mandal and Laik1 reported an experimental study of the formation and dissociation of ethane hydrate in the presence of an anionic surfactant, sodium dodecyl sulfate (SDS). This paper has many serious flaws. Some of the experimental data provided there are doubtful or even scientifically impossible. Moreover, the authors of the paper argued the physicochemical mechanism of the SDS effect on hydrate formation, arbitrarily disregarding recent progress in our understanding of this matter, and drew a disputable conclusion without showing any clear evidence for it. This communication aims to indicate doubtful or obviously erroneous points in the experimental data provided in the above paper and to dispute some arguments stated by the authors of the paper.
