| Summary: | Methane is a potential alternative energy source which is abundant and produces lower
CO2 emissions when it is used as fuel due to the content of C in the methane molecule is
much lesser than its H content. Besides in a form of gas, methane in nature can also be in
the form of methane hydrates. The formation process of methane hydrates in nature can
be adopted as a method of storage of methane. In this study, a thermodynamics review
will be studied related to temperature and pressure in a phase equilibrium system of
methane hydrate . Thermodynamic model aims to predict the stability of methane
hydrates for effective storage of methane. Each volume of methane hydrate contains as
164 volumes of methane gas under standard conditions ( STP ) . The study was conducted
by adsorbing methane on a wet porous carbon with the method of static volumetric.
Adsorption system was conditioned at the temperature of 274 K , 275 K , 276 K and 277
K. Methane gas is injected into the clean vacuum system, at various pressures . the
adsorption equilibrium was Indicated by stable pressure in the adsorption system . Moles
of methane adsorbed was calculated from the difference of mole before and after
adsorption.The Pressure when methane hydrate formed can be seen from the point where
the number of moles of methane adsorbed increased significantly . The experimental
results show that at the temperature of 274 K methane hydrates was formed at a pressure
of 2.75 MPa
