Abstract
We study the features of multiple composition natural gas in stability zones and occurrence zones of hydrate in seafloor. First, the stability surface of hydrate formation with multiple composition natural gas including methane and propane is set up by regression fitting. The effect of salinity in liquid on stability curved surface is considered by interpolation. Based on the model of hydrate prediction, the ranges of stability zones and occurrence zones are computed for only methane or different fractions of methane and propane with different salinity. Comparing these results, we find that the effect of little propane on stability zones and occurrence zones is stronger than that of single methane gas. Apparently, it is because propane has larger effect on the stability temperature and the solubility of natural gas. The effects of other compositions such as CO2, C2H6 and H2S are briefly discussed in the paper.
