Entitled “Supersonic gas dehydration in pipeline using Joule Thomson Valve”, this project ultimately aims to introduce a new technology, Joule Thomson valve to separate water from natural gas (from reservoir) using supersonic flow and joule Thomson cooling effect. Due to time and financial constraints, this project is only being done in simulation, not in term of experiment. Gas dehydration in pipeline is essential because water content in the gas system could cause large pressure drop and corrosions that will be enhanced by the presence of H2S and CO2 typically associated in sour gas. The current technologies used are membrane and absorption separation technique. However, they required high CAPEX, OPEX and maintenance works. Separation using Joule Thomson valve is technically and economically feasible.
