Abstract

Proses insinerasi menghasilkan emisi gas yang dapat membahayakan atmosfer dan lingkungan apabila tidak ditangani dengan baik. Salah satu penanganan emisi ini dapat menggunakan wet scrubber baik countercurrent atau cocurrent. Dua jenis ini memiliki keuntungan dan kekurangannya masing-masing yang masih perlu dibahas secara mendalam. Maka dalam kajian akan ditentukan dimensi wet scrubber yang mencukupi untuk menyisihkan emisi SO2 dengan pengaruh kedua arah aliran. Pada kajian menggunakan data operasional wet scrubber di Departemen Teknik Lingkungan ITS. Lalu dilakukan perhitungan Hog dari penelitian sebelumnya dan pencarian nilai teoritis L/G dengan L/G berdasarkan penelitian sebelumnya. Nilai Hog akan digunakan untuk mencari tinggi pack yang diinginkan berdasarkan L/G teoritis. L/G ini digunakan sebagai pembanding untuk mendapatkan Nog untuk mencari tinggi dimesi packing. Selain itu L/G ini digunakan sebagai nilai konstanta pembanding untuk mencari ketinggian berdasarkan penelitian sebelumnya. Setelah itu dilakukan pencarian pengaruh kedua arah aliran dengan melihat Extraction Rate pada masing-masing aliran. Berdasarkan diameter yang dikaji (0,61 m), tinggi yang sesuai atau mencukupi untuk wet scrubber yang dikaji sebesar 24,2 cm. Effisiensi pada countercurrent dan cocurrent diperoleh dengan rata-rata 82,3% dan 75%. Penyisihan arah aliran cocurrent secara teoritis tidak memenuhi baku mutu SO2 sesuai Permen LHK 70/2016. Sedangkan countercurrent masih memenuhi baku mutu dalam 3 menit diantara 10 menit percobaan. ======================================================================================================= The incineration process produces gas emissions that can endanger the atmosphere and environment if not handled properly. One of these emission treatments can use wet scrubbers, either countercurrent or cocurrent. These two types have their respective advantages and disadvantages that still need to be discussed in depth. So in the study, it will be determined the dimensions of the wet scrubber sufficient to remove SO2 emissions with the influence of both flow directions. The study used wet scrubber operational data at the ITS Environmental Engineering Department. Then calculate the Hog calculation from previous research and search for the theoretical value of L/G with L/G based on previous research. The Hog value will be used to find the desired pack height based on theoretical L/G. This L/G is used as a comparison to get Nog to find the height of the packing dimension. In addition, L/G is used as a constant value of comparison to find the height based on previous research. After that, a search for the effect of both flow directions is carried out by looking at the Extraction Rate in each flow. Based on the diameter studied (0.61 m), the height suitable or sufficient for the wet scrubber under study is 24.2 cm. The efficiency of countercurrent and co-current was obtained by an average of 82.3% and 75%. The theoretical allowance for cocurrent flow direction does not meet the SO2 quality standard according to the Minister of Environment and Forestry Regulation 70/2016. Meanwhile, the countercurrent still meets the quality standard within 3 minutes between 10 minutes of the experiment.
