A new quasi steady-state (QSS) model is proposed to describe the dissociation of gas hydrates in pipelines. The model has been constructed for both Cartesian and cylindrical co-ordinates, and modelled for two-sided depressurisation. The QSS model proves to be an excellent tool for predicting plug dissociation time when compared with experimental data, and the simplicity of the model has major advantages compared to existing models.
