Modeling and Optimization of LNG Processes
MetadataShow full item record
This thesis presents a solution to an optimization tool for LNG process design. The work includes an open source application developed in order to design and simulate compressors. Although the aim of the work is LNG processes, the application does also apply for compressors utilized in other applications areas. With compressors as core emphasis, compressor theory is presented; i.e. dynamic compressors which are of most relevance are presented with respectively: Axial flow and Centrifugal flow compressor theory.Development of the application is done with Matlab programming, and the results from the application are presented and validated with four different validation points. Validation of the application is done with similar compressor cases created in Aspen HYSYS. Comparison to Aspen HYSYS is to relate this application to an accepted and widely used commercial process modeling software.
