Abstract
A mathematical simulation of the gas hydrate formation based on a gas mixture approximated to natural gas composition – CH4+H2S + CO2+Xe at a normalized increase in hydrogen sulfide (H2S) concentration in gas mixture from 3.08·10−4 vol.% to 4.88 vol.%, at changes in the gas hydrate formation temperatures from 273.15 K to 283.15 K. It is shown that xenon (Xe) distribution coefficient decreases from 12.37 to 5.90, and is more dependent on the change in H2S concentration than on the change in the gas hydrate formation temperature. Effective Xe recovery from natural gas at the gas hydrate formation temperature is 273.15 K, and at a minimum impurity concentration with a dissociation pressure close to Xe.
