Abstract

Transportation and distribution of natural gas are the most important subjects of gas industries in the country, because internal consumption or for exporting it. One of the problems that may be occurred in transportation lines is formation of GAS HYDRATE crystals. STABILITY calculation must be done before the flash calculation to determine the number of phases that exist in equilibrium conditions. In this research STABILITY analysis of systems that containing GAS HYDRATE was done by minimization of distance of tangent plane of GIBBS FREE ENERGY of system by GENETIC ALGORITHM method. Because of non linear behavior of systems these multi component multi phase calculation were complex, thus the random optimization methods like (GA) was preferred. In this paper calculation of fugacity of components in vapor and liquid phase was done by using VPT equation of state and for solid phase VDW-P was used. In this work this calculation was performed for systems like methane-water (crystal I), methane-ethane-water (crystal I), methane-propane water (crystal II), methane-ethane-propane-water (crystal II), for 274 K and different pressures.
