Experimental study on gas hydrate formation from natural gas mixture

• Isochoric and isothermal experiments were conducted on the mixture of natural gas.
• Rate of natural-gas consumption by hydrate is determined based on experiments.
• It is shown that the rate of hydrate formation is exponentially proportional to pressure driving force.

In this work, gas consumption by clathrate hydrate from mixture of natural gas at different pressures and temperatures (275.15–287.25 K and 1.1–5.4 MPa) are reported. The experiments were conducted in a stirred-reactor tank in isothermal and isochoric conditions. The amount of consumed gas by the hydrate phase was determined considering the pressure reduction during the experiments. Results show the rate of gas consumption is exponentially related to the over-pressurizing of the system.
