Abstract

Penanganan untuk mengurangi dan pemanfaatan limbah plastik masih belum optimal. Volume limbah plastik terus bertambah seiring bertambahnya jumlah penduduk. Limbah plastik merupakan sumber pencemaran lingkungan yang sulit terdegradasi. Tujuan dari penelitian ini adalah mengkaji pengaruh komposisi arang limbah plastik sebagai bahan baku briket terhadap analisa proksimat. Limbah plastik yang digunakan adalah tutup botol dan kemasan makanan ringan. Pirolisis dilakukan pada suhu 450oC untuk tutup botol dan 280oC untuk kemasan makanan ringan dengan lama prosesnya 60 menit. Ukuran partikel arang plastik adalah 40,60, dan 100 mesh. Komposisi arang plastik tutup botol dan makanan ringan dikombinasikan 1:90; 50:50; 90:1 dengan penambahan tepung tapioka sebagai perekat. Analisa yang dilakukan terhadap briket plastik ini adalah proksimat meliputi kandungan air, abu, volatile matter, karbon terikat dan nilai kalor. Berdasarkan hasil analisa proksimat didapatkan kandungan air 5,47%, kadar abu 4,95%, volatile matter 13, kadar karbon terikat 76,58% dan nilai kalor sebesar 8565,914 cal/gram. Data analisa proksimat yang didapatkan sudah memenuhi standar SNI. Kata kunci : Limbah, Plastik, Briket, Kompoisi, Proksimat.

Abstract

Proper processing to overcome the abundance of plastic waste is needed. Currently, pyrolysis technology is one method that can overcome plastic waste. Pyrolysis is a thermochemical process, which breaks down long alkyl chains into hydrocarbons at high temperatures. This study aims to determine the effect of temperature on yield and heating value using the analysis of variance (ANOVA) method. The pyrolysis of plastic waste is carried out with HDPE plastic material. The pyrolysis process is carried out in a reactor with 50 grams of feed at various temperatures of 500, 550, 600 and 650⁰C. The conclusion that can be drawn from this research is that there is a decrease in yield and calorific value with increasing temperature. The results of the analysis concluded that temperature had an effect on the yield produced and the calorific value of the product. The best yield was obtained at 35.86% and a heating value of 10530.461cal / g at a temperature of 100oC. Based on the results of data analysis using the ANOVA method, it was found that the experimental hypothesis was that temperature had an effect on yield and calorific value.

Abstract

An absorber is a tool used in the absorption process to separate a certain gas component from a gas mixture using a chemical solution as an absorbent. This simulation aimed to determine the effects of the packing type and column diameter on flooding, the packing type and column diameter on pressure drop, and the gas flow rate on CO2 removal. It also investigated the best absorber design based on %flooding and pressure drop. This simulation was carried out using the Aspen Hysys software version V.10. The variables of packing type consisted of PALL, berl, and raschig. The simulation results indicated that the larger the column diameter for each type of packing, the smaller the %flooding value. Meanwhile, the limit value of the %flooding for each type of packing given by Aspen Hysys was 30%– 80%. Further simulation results showed that the larger the column diameter in each type of packing, the smaller the pressure drop value. The pressure drop limit value given by Aspen Hysys was 3,658 mbar. In addition, the next simulation results demonstrated that the greater the value of the given gas flow rate, the greater the % CO2 removal value. Thus, the effective absorber design viewed from the %flooding and pressure drop was a 0.5-inch berl dimension with ceramic material. Keywords: absorber, type of packing, flooding, pressure drop, CO2 removai

Abstract

Absorpsi merupakan salah satu metode yang digunakan untuk memisahkan gas CO2 dalam suatu campuran gas. CO2 perlu dihilangkan karena akan menganggu suatu proses pabrik dan dapat menyebabkan polusi udara.  Penelitian dilakukan dengan tujuan untuk memperoleh desain kolom absorber tipe packed tower dan mengetahui pengaruh konsentrasi dan laju alir absorben KOH terhadap removal CO2. Tahap pertama yang dilakukan yaitu menentukan desain kolom pada kondisi laju alir CO2 2 L/menit dengan laju alir absorben KOH 0,1N 2 L/menit. Uji kinerja absorber dilakukan dengan variasi laju alir absorben 1 L/menit; 1,25 L/menit; 1,5 L/menit; 1,75 L/menit; dan 2 L/menit pada konsentrasi KOH 0,1 N; 0;3 N; dan 0,5 N. Berdasarkan analisa asidi-alkalimetri diperoleh removal CO2 tertinggi mencapai 95,743% pada laju alir absorben KOH 0,5N sebesar 2 L/menit, pada kolom absorber dengan diameter 5,96 cm dengan tinggi kolom 84,5 cm menggunakan ceramic-rasching ring 13 mm yang diisikan mencapai ketinggian 83,5 cm. Hasil penelitian menunjukkan bahwa peningkatan laju alir volumetrik dan konsentrasi KOH sebagai absorben menyebabkan nilai removal CO2 semakin besar.
