Laboratory Frontiers in Determining the Packing Style Effect in Carbon Dioxide Hydrates Formation

Methane production in sequestration process and reducing atmospheric carbon dioxide, a main source of greenhouse gas, has been accentuated recently. An orderly packing style for hydrate will play a fundamental role in hydrate formation rate and efficiency of free water. Surfactant has been reported to help orient hydrocarbon hydrate packing along a metal wall. In this work, it was shown that hydrate packing styles played an important role in carbon dioxide hydrate formation rate. Packing facilitates a high hydrate formation rate and high percentage conversion. Furthermore, in this research, a camera with borescope was used to observe and record the image of carbon dioxide hydrate when it formed with addition of Surfactin, Emulsan, Rhamnolipid, SDS micellar, FS-62/SDS and FSP/SDS into the water solution. We have shown that a full development of the hydrate in the test cell could be obtained with use of FS-62/SDS or FSP/SDS.
