Abstract

Within the EU-funded GeoCapacity project an economic analysis computer tool is developed for the evaluation of carbon capture and storage (CCS) systems comprising of a set of multiple sources of CO2 and storage locations. As a part of that tool, an algorithm has been developed to create low-cost pipeline networks to connect sources of CO2 and storage reservoirs. The main features of the algorithm are: •Input parameters are the size and location of CO2 sources and storage reservoirs•The algorithm determines the trajectory, capacity and costs of the connecting pipes•If necessary junctions are created, i.e. connections are created between sources and pipelines and/or storage locations and pipelines•The algorithm has a step wise approach. The pipeline network is built-up by successively adding a pipe in each step, until all sources are connected to storage reservoirs•In each step all possible combinations are examined and the one with the lowest costs is added to the system•The pipe costs have a non linear relation with the flow rate•Cost ranges for pipeline network are presented reflecting uncertainties in data of supply of CO2 from sources as well in storage capacity of sinks. © 2009 Elsevier Ltd.

Abstract

In this work a review about the most relevant methods found in the literature to model the multiphase flow in pipelines is presented -- It includes the traditional simplified and mechanistic models, moreover, principles of the drift flux model and the two fluid model are explained -- Even though, it is possible to find several models in the literature, no one is able to reproduce all flow conditions presented in the oil industry -- Therefore, some issues reported by different authors related to model validation are here also discussed En este trabajo se presenta una revisión de los métodos más relevantes en la industria del petróleo para modelar el flujo multifásico en tuberías -- Se incluyen desde los modelos simplificados hasta los modelos mecanicistas además de explicar los principios de los modelos drift flux y two fluid -- Existe una gran cantidad de modelos en la literatura para simular el flujo multifásico en tuberías, empero, ningún modelo es capaz de reproducir todas las condiciones de flujo multifásico presentes en la industria del petróleo -- Finalmente, se mencionan algunos temas en los que se requiere más investigación que lleven a simulaciones con resultados más cercanos a los datos de pozos reale Document type: Article
