Prediction of Gas Hydrate Formation Using Hysys Software

Gas hydrates attracted worldwide attention due to their potential as huge energy resource in the recent decades. effective parameters which influence the formation of hydrates are high pressure, low temperature and water presence. hysys software is one of the major simulators which is widely used in chemical and thermodynamic processes.this research was conducted to simulategas hydrateformation of lavan-3 gas well and salman gas field using the hysys software. the steady statesimulation of hydrate formationwas performed by the peng-robinson equation of state. the predicted data were compared with experimental ones. it was concluded that hysys is able to predict hydrateformation with the average absolute error of less than 1%. two novel correlations were also developed to estimate hydrate formation conditions for natural gas.
