Paper Title:
SDS Effect on CH4/N2/O2 Hydrate Formation Rate for CMM Separation and Storage
  Abstract

The new methods for separating, storing and transporting drained coal mine methane (CMM) is based on gas hydrate formation. The kinetic hydration process is studied experimentally in detail for two kinds of synthesized CMM with three concentratons of SDS solution. The hydration rates in six experimental systems are calculated using the self-established model to compare the effect of SDS. The results show that the establised model can precisely calculate the hydration rate; SDS decreases the gas hydration rate. This is due to the reason that SDS in the hydrate growth stage, can strengthen the hydrogen bond of water molecules, and be absorbed to the metal wall of the high pressure cell, the SDS membrane can react with mine gas and form crystal nucleus, thus, the hydrate formation rate is raised. It can provide the reference for seeking the optimal surfactants in the hydrate formation process for the mixed gas.
