Depending on the complexity of the problems, different approaches may be taken to assess the potential impacts of Joule-Thomson effect. One simple approach would be to use a reasonable PVT model to predict the Joule-Thomson effect associated with a pressure drop. Another approach, which is more comprehensive and could be applied to both steady-state and transient (dynamic) fluid flow process, would be to rely on a well-established transient multiphase flow simulation software (e.g., OLGA [12]) to calculate the change in pressure and temperature at different locations of interest. Both approaches have been applied in a series of studies conducted and selected results are to be presented in the next two sections.
