Abstract:

Kaduna refining and petrochemicals company thermal power plant in Nigeria that cogenerates steam and electricity is faced with deterioration from its design output and excess fuel consumption. A simulation program for energetic and exergetic analysis of the thermal power plant was developed and validated in free and open-source literature based on the object-oriented programming language. The procedure to transform a mathematical model into a Python-based simulation program is shown. The article contains an algorithm for simulating the selected components. Herein, the simulation models of the Deaerator 1, HP Heater 1, and Condenser 1 were validated based on the literature' data. The energy and exergy analysis identified the losses, destructions, and efficiencies of the components. The validated results are graphically presented in charts. In the input interphase, the corresponding enthalpies, entropies, and the specific exergies were obtained as input data are considered. The program calculated the losses, destructions and efficiencies of the components, and the output interphases displayed the results. The results were validated by comparing it with the data of the referenced literature. It was revealed that the outputs from the program showed a very good agreement with the operational data from the literature.
