Gas expansion through the porous plug will experience the Joule-Thomson effect. Joule-Thomson effect can be interpreted as the e¤ect of temperature change with the change in pressure when gas expands at constant enthalpy. The unit of this effect is called Joule-Thomson coeficient. In natural gas production, gas ‡ows from the reservoir to the bottom of the pipe. Joule-Thomson effect occurs to this condition, which results in temperature at the bottom of the pipe will not be the same as the temperature in reservoir. However, in reality the calculation of temperature distribution along pipeline still consider that the temperature at the bottom of the well equals to the temperature in reservoir. In other words, the Joule-Thomson effect is always ignored. Joule-Thomson coefficient can be determined by a variety of ways. This thesis describes the derivation of Joule-Thomson coefficient using thermody- namics approach, Maxwell Relation, and Equation Of State. Equation Of State that is used in this thesis are Van der Waals and Beattie-Bridgeman.
