Abstract

Dalam penilitian ini akan dituliskan penelitian mengenai Carbon Capture and Utilization dengan menggunakan metode Supersonic Separator (SS) Carbon Capture. SS Carbon Capture ini akan digunakan sebagai sistem tambahan pada PLTGU sebagai carbon separator pada flue gas yang dihasilkan. SS Carbon Capture memiliki keunggulan dalam sistem yang sederhana dan dapat diandalkan, kehilangan tekanan rendah, efisiensi pemisahan tinggi, dan tidak menimbulkan polusi sekunder. Beberapa Variabel yang akan dianalisis yaitu seperti komposisi, suhu, dan komposisi keluaran. Tujuan dari penelitian ini diharapkan dapat mengetahui hasil uji peforma dari natural gas processing plant dengan menerapkan Supersonic Separator, mengetahui jumlah kandungan CO2 pada gas buang yang dihasilkan, mengetahui analisis exergy dari rangkaian sistem. Pada desain sistem post-combustion NGCC harus ditambahkkan 2 separator dan 3 buah cooler tambahan untuk mencapai suhu dan tekanan yang optimal agar dapat diproses di dalam Supersonic Separator. Pada Supersonic Separator menunjukkan hasil proses pemisahan konsentrasi CO2 menjadi output udara kering (dryout) dan droplet uap air (wetout). Pada variasi flue gas 1 , kinerja SS akan mencapai maksimal sekitar 3,015 kg/h pada tekanan 11 bar. Hasil perbandingan jumlah input senyawa pada variasi flue gas 2 terhadap tekanan akan menunjukkan kinerja SS yang mencapai performa maksimalnya sekitar 1945,096 kg/jam pada tekanan 71 bar. Pada hasil performa SS dengan input variasi flue gas 1 menunjukkan persentase penangkapan CO2 dan N2 secara berturut-turut mencapai 94,20% dan 97,48%. Selanjutnya, hasil performa SS dengan input variasi flue gas 2 menunjukkan persentase penangkapan CO2 dan N2 secara berturut-turut mencapai 91,28% dan 98,28%. Diketahui bahwa kinerja tiap komponen SS dengan diberikan input variasi flue gas 1 menghasilkan persentase exergy sebesar 98,82% untuk hampir semua peralatan. Selanjutnya, kinerja SS dengan input variasi flue gas 2 menunjukkan kehilangan exergi yang signifikan, terutama pada peralatan cooler dan compressor dengan total nilai rata-rata exergy sebesar 78%

In this study, research on Carbon Capture and Utilization using the Supersonic Separator (SS) Carbon Capture method will be written. SS Carbon Capture will be used as an additional system in PLTGU as a carbon separator in the flue gas produced. SS Carbon Capture has advantages in a simple and reliable system, low pressure loss, high separation efficiency, and does not cause secondary pollution. Some variables that will be analyzed are composition, temperature, and output composition. The purpose of this study is expected to determine the results of the performance test of the natural gas processing plant by applying the Supersonic Separator, to determine the amount of CO2 content in the flue gas produced, to determine the exergy analysis of the system circuit. In the design of the NGCC post-combustion system, 2 separators and 3 additional coolers must be added to achieve optimal temperature and pressure so that it can be processed in the Supersonic Separator. The Supersonic Separator shows the results of the CO2 concentration separation process into dry air output (dryout) and water vapor droplets (wetout). In flue gas variation 1, the SS performance will reach a maximum of around 3,015 kg/h at a pressure of 11 bar. The results of the comparison of the amount of compound input in flue gas variation 2 to the pressure will show the SS performance reaching its maximum performance of around 1945.096 kg/h at a pressure of 71 bar. The results of the SS performance with flue gas variation input 1 show the percentage of CO2 and N2 capture respectively reaching 94.20% and 97.48%. Furthermore, the results of the SS performance with flue gas variation input 2 show the percentage of CO2 and N2 capture respectively reaching 91.28% and 98.28%. It is known that the performance of each SS component with flue gas variation input 1 produces an exergy percentage of 98.82% for almost all equipment. Furthermore, the performance of the SS with flue gas variation input 2 shows significant exergy loss, especially in cooler and compressor equipment with a total average exergy value of 78%
