| Summary: | <p> </p><p><strong>LANGMUIR ADSORPTION MODEL FOR DINITROGEN MONOXIDE IN BIOFILTER SYSTEM USING COMPOST FERTILIZER MEDIUM.</strong><em> Nitrous oxide (N<sub>2</sub>O) is mostly emitted from various industrial processes and agricultural activities. This gas causes serious environmental problems and is considered as a dangerous pollutant. In the past, traditional control tec</em><em>hnologies, such as Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR), were applied to control N<sub>2</sub>O emissions in some industries. However, these two processes required high temperatures and the use of catalysts</em><em>.</em><em> </em><em>Economic and technical constraints in SCR and SNCR methods motivated researchers to develop new, cost-effective processes to remove N<sub>2</sub>O. </em><em>Biofiltration is an emerging technology that offers a number of advantages over traditional methods of air pollution control</em><em>. The purpose of this research is to modelise the biofiltration experimental results into the Langmuir adsorption model</em><em>. This research is conducted in laboratory scale biofilter column, with parameters studied are effect of biofilter length and N<sub>2</sub>O gas flowrate. </em><em>The result of the model is simulated into sensitivity analysis. The </em><em>average </em><em>Langmuir constant obtained in the model of the research is 16.006 liter/mol.</em></p><p> </p><p><em>Dinitrogen Monoksida (N<sub>2</sub>O) merupakan emisi dari proses industri dan kegiatan </em><em>pertanian</em><em>. Gas tersebut merupakan gas polutan berbahaya dan menyebabkan masalah lingkungan yang serius. </em><em>Sebelumnya, teknologi kontrol tradisional seperti Selective Catalytic Reduction (SCR) dan Selective Non-Catalytic Reduction (SNCR) digunakan untuk mengontrol emisi N<sub>2</sub>O pada kegiatan-kegiatan industri. </em><em>Akan tetapi, kedua proses ini membutuhkan suhu yang tinggi dan penggunaan katalis</em><em>. </em><em>Adanya masalah dari segi ekonomi dan teknis memotivasi peneliti untuk mengembangkan teknologi baru yang lebih murah dan efisien untuk menghilangkan N<sub>2</sub>O dari gas buangan. Pengolahan N<sub>2</sub>O secara biologis dalam</em><em> </em><em>proses </em><em>biof</em><em>i</em><em>ltrasi </em><em>adalah salah satu alternatif ramah lingkungan yang dapat digunakan dalam pengelolaan emisi industri. </em><em>Penelitian ini bertujuan untuk menggambarkan hasil biofiltrasi gas N<sub>2</sub>O</em><em> dengan medium pupuk kompos</em><em> </em><em>dalam</em><em> bentuk</em><em> model</em><em> adsorpsi Langmuir. Penelitian dilakukan dalam kolom biofilter skala laboratorium, dan parameter-parameter yang diteliti adalah pengaruh dari ketinggian biofilter dan laju alir gas N<sub>2</sub>O. Hasil dari pemodelan kemudian disimulasikan dalam analisis sensitivitas.</em><em> </em><em>Nilai konstanta Langmuir</em><em> rata-rata </em><em>yang didapatkan dari pemodelan penelitian ini adalah 16</em><em>,</em><em>006 liter/mol.</em></p> |
