Abstract

The rapid development of Crude Palm Oil (CPO) production has led to an increase in the production of Palm Oil Mill Effluent (POME) as well. POME will cause problems in the environment because contains high contaminants. This study aims to investigate the effect of the coagulant Polyaluminium Chloride (PAC) variations and the membrane’s operating pressure on the POME treatment process using the nanofiltration membrane (NF) with the coagulation-flocculation process as pre-treatment. The PAC was used in the coagulation-flocculation process with variations in concentration (5.0; 5.5; 6.0; 6.5; 7.0 g/L). The process was completed by a rapid stirring of 200 rpm for 5 minutes, followed with slow stirring at 60 rpm for 15 minutes and settling time for 30 minutes. The process of membrane nanofiltration was carried out for 60 minutes with variations in operating pressure (8.0; 9.0; and 10 bars). In each treatment process, effluent quality testing was carried out with Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS) and oil/fat as parameters. In addition, an analysis of permeate fluxes and rejection of NF membrane was also carried out. The results of the analysis suggested that the best coagulant doses are 6.0 g/L with the reduction percentage of BOD, COD, TSS and oil/fat at 78.85%; 68.57%; 92.77% and 92.31% respectively. The highest percentage of NF membrane rejection was found at a pressure of 10 bar, which is equal to 94.71%; 94.86%; 97.92% and 95% respectively for BOD, COD, TSS and oil/fat with a flux value of 7.16 L/m2.hours.

Abstract

Penelitian ini dilakukan untuk mengkonversi sampah plastik menjadi bahan bakar minyak menggunakan katalis Zeolit X yang disintesis dari abu layang batubara yang selanjutnya dikarakterisasi menggunakan XRD. Dalam penelitan ini, sebanyak 100 gram plastik jenis polypropylene direngkah di dalam reaktor batch pada suhu 350o C, 400o C dan 450o C selama 60 menit dengan variasi rasio katalis/plastik 0,5; 1; 1,5 (% berat). Yield (%) tertinggi adalah 76,09% yang diperoleh pada variasi suhu 450o C dan rasio katalis/plastik 1,5%. Nilai kalor produk adalah 45,56 MJ/kg. Hasil analisa GC-MS menunjukkan % area produk mengandung bahan bakar seperti bensin (60,46%), kerosin dan solar (7,48%).

Abstract

Bahan bakar minyak merupakan sumber energi terpenting untuk kehidupan manusia. Produksi bahan bakar minyak yang berasal dari bahan bakar fosil semakin hari semakin menurun. Untuk itu diperlukan suatu alternatif sumber energi yang dapat diperbaharui dalam menggantikan bahan bakar fosil, salah satunya adalah mengkonversikan biomas menjadi biooil. Dalam penelitian ini digunakan limbah padat sawit, yaitu batang dan tandan kosong sawit dengan ukuran partikel 2-6 dan 6-10 mesh. Proses yang digunakan untuk mengkonversikan limbah padat sawit pada penelitian ini yaitu slow pyrolysis. Proses ini dilakukan pada reaktor pipa stainless steel dengan diameter 3,81 cm dan panjang 60 cm, pada kisaran temperatur 450-600oC yang dialiri gas nitrogen. Hasil yield tertinggi dicapai pada suhu 500oC dengan diameter partikel 2-6 mesh. Produk bio-oil dilakukan analisa dengan menggunakan GC HP 5890 II. Pada produk bio-oil juga teridentifikasi adanya etanol, benzena, toluena dan xylen.Kata kunci: bio-oil, limbah padat sawit, pyrolysis
