Layout and modeling of a high temperature heat storage system for continuous operation of a solar reforming processes
| Summary: | This thesis comprises a model of a high temperature heat storage system, modelled in Aspen Custom Modeler®, to be implemented in a solar methane reforming plant model. The model is a 1D approximation and does not consider thermal losses. The pressure drop along the system is considered as well as the temperature dependency of the fluid properties. The system modeled is a sensible heat storage system and uses alumina ceramic honeycombs as storage material. The implementation of the storage system in a solar methane reforming plant will make possible to reduce the size of the plant, increase the operating period of the plant and achieve a constant annual output of the plant. The thesis also presents a short state of the art in heat storage systems. The main objective of the thesis is to model the heat storage system to be implemented in a continuous operation simulation and also determine a relation between the layout of the system and the operating time of the plant. |
