Removal of Equilibrium Water in Natural Gas Using Joule-Thomson Expansion Valve

Removal of water in natural gas is required at the preliminary stage of gas processing. There are several methods that can be applied for the dehydration of water such as absorption, adsorption, physical membrane and condensation process. For this project, condensation method will be used to remove excess water from the natural gas by introducing the Joule-Thomson effect. The Joule-Thomson effect can be observed through a valve where the water will start to condense by throttling the pressure from high level to low level. Two types of data gathering technique being done for this project which are by experimental feasibility and numerical analysis using process simulation. For the experimental feasibility, the temperature for the Joule-Thomson effect was recorded and compared using simulation. For numerical analysis using process simulation, a range of pressure is being test to find out what are the percentage of water recovery by using a Joule-Thomson valve and an expander with two different compositions which are 80% methane 20% carbon dioxide and 50% methane 50% carbon dioxide.. The implementation of this data for future is a suitable and economical way can be used to remove water from the natural just by having a Joule-Thomson effect and its valve rather than using other methods such as absorption, a compressor or membrane technologies.
