Abstract: (952 Views) |
In this study, the energy consumption quality of NGL plant 800 from National Oil Companies of Southern Iran, located in Ahvaz, has been accurately evaluated based on exergy analysis and using MATLAB software. The energy consumption quality is an indicator that directly affects the economic growth of any country and the exergy analysis method is a key issue for identifying the inefficiency locations, causes, and magnitudes of a process. In this regard, by defining the fuel-product methodology, two essential parameters were investigated and discussed in the NGL plant equipment. Thus, using the coding capability of MATLAB software and after replacing the modeling results of the ASPEN HYSYS simulator in the flow exergy rate equations, two indices of exergy destruction and exergy efficiency of the NGL plant equipment were calculated and evaluated. The evaluation results of the two indicators of exergy destruction and exergy efficiency show that the highest exergy destruction rate is in compressors K103 and heat exchanger E-101 with 510 and 629 kW respectively. The E101 heat exchanger has the lowest exergy efficiency of 16%. Also, the considerations show that the exergy destruction of the compressor (K103) and heat exchanger (E-101) will reduce by improving the performance of these components. |
