Efek Rasio Umpan Co-Gasifikasi Batu Bara dan Tandan Kosong Kelapa Sawit terhadap Produksi Metanol: Studi Simulasi
Get PDFMetanol memiliki banyak kegunaan di berbagai bidang, baik sebagai senyawa kimia antara untuk diproses lebih lanjut, sebagai penyusun sebuah senyawa kimia akhir, maupun sebagai bahan bakar. Fleksibilitas penggunaan metanol menjadikan peranannya strategis dalam pengembangan bahan kimia dan energi masa depan. Penelitian ini mengkaji efek rasio umpan batu bara dan tandan kosong kelapa sawit pada proses co-gasifikasi untuk menghasilkan metanol, dengan melakukan studi simulasi di piranti lunak Aspen Plus v.11. Variasi rasio tersebut adalah 100-0, 85-15, 70-30, 50-50, 30-70, 15-85, dan 0-100, di mana rasio 100-0 menunjukkan proses gasifikasi batu bara murni. Performa proses diukur dengan menggunakan parameter process mass intensity (PMI), yaitu parameter yang lazim diterapkan di dunia industri untuk mengevaluasi aspek berkelanjutan sebuah proses. Hasil penelitian ini menunjukkan bahwa berkurangnya komposisi batu bara pada umpan co-gasifikasi menyebabkan terjadinya penurunan kandungan CO pada syngas. Hal ini menyebabkan penurunan produktivitas proses sintesis metanol, yang diindikasikan dengan meningkatnya nilai PMI. Selain itu, penelitian ini juga menghasilkan luaran berupa tren PMI terhadap komposisi batu bara di dalam umpan. Tren tersebut memberikan sebuah persamaan polinomial beroder dua (y = 0,0002x2 – 0,0481x + 5,3381) yang berguna bagi para perancang pabrik untuk memprediksi secara cepat mengenai jumlah metanol yang dapat dihasilkan apabila rasio umpan co-gasifikasi divariasikan

Extraction of Vegetable Oil from Candlenut Seeds (Aleurites Moluccana L. Willd.) Using the Microwave Hydrodiffusion and Gravity (MHG) Method
Get PDFThe microwave hydriffusion gravity (MHG) method is a relatively new extraction method in order to improve the quality of oil obtained from plant materials or spices. The extraction process is carried out without involving solvents so it is safe for consumption. However, the MHG method has never been applied to the extraction of candlenut (Aleurites moluccana L) seeds. The operating conditions and variables in the research on the extraction process of Aleurites moluccana L are microwave power (300; 450; 600 W), extraction time (15-75 minutes) with 15-minute intervals, material size (1;2;3 cm), mass of raw material 100 gr, and atmospheric pressure. Material treatment consisted of 3 types of material conditions including seed material which had been roasted for 10 minutes over low heat, seed material which had been in the oven for 45 minutes, and seed material which had been without pretreatment. The results of the oil extract were analyzed using GC-MS to identify the components of the constituent compounds. Then, evaluating the mathematical modeling of the extraction process is based on first and second order kinetics. Roasted material showed the highest yield with material size parameter in 1 cm, microwave power of 600 W, and extraction time at 30 minutes, produced 5.55% (%w/w). Furthermore, the pyrazine component (36.814%) is the largest compound from the extraction of Aleurites moluccana. The first-order kinetic model has a regression that is close to the experiment with (R2 = 0.9453). Modeling quality is also supported by a very small total sum of squares (SST) value of 6,44E10-4. Therefore, the MHG method is quite effective in producing Aleurites moluccana oil with better quantity and qualit
