Abstract

One of the methods of ethanol mixture separation is distilation with addition of potassium chloride salt as entrainer. The aim of this research is to determine the effect of salt additiont and the reflux ratio, to ethanol product concentration, and also determine the best operating condition of the highest ethanol concentration in the distillation product.  The material used in the research are ethanol, potassium chloride and water. Equipment used is a series of sieve tray type distillation tower in diameter of 2.5 inch. Variable used in this research are: potassium chloride salt addition (0; 5; 10) grams/liter of alcohol solution, the concentration of ethanol feed (10; 50; 90) weight percent and  reflux ratio (0,5; 1; 1.5 ), the fixed variable are  ethanol feed in 4th tray, the flow rate (1250 ml/min), destillation time (120 minutes), and the number of sieve tray (11 trays). The research were carried out by introducing ethanol in specific concentration into the feed storage and reboiler and also potassium chloride into the salt storage. The reboiler is heated until evaporation of ethanol occur and distillation were carried out. Ethanol as product of distillation are measured its volume and concentration. The result is that the highest ethanol concentration is 98% by concentration of  feed  (50-90)%, addition of potassium chloride salt of 10 g rams/ liter, and  reflux ratio of 1.5.

Abstract- One of the most widely used processes for CO2 gas removal is Absorption. Carbon dioxide is the result of the fuel combustion process which of the hazardous gases. The aim of this research is to determine the total mass transfer coefficient and analyze the effect of the absorbent flow rate of the absorbent solution with the promoter and the gas flow rate to the total mass transfer coefficient value. The variables consisted of liquid flow rate: 1, 2, 3, 4, 5 liter/min, gas flow rate: 15, 25, 30, 40, 50 liter/min and MSG concentration: 0%, 1%, 3% and 5% by weight. The solution of Pottasium Carbonate as absorbent with MSG promoter is flowed through top column and CO2 gas flowed from bottom packed column. Liquids were analyzed by titration and the gas output was analyzed by GC. From this research, it is found that the flow rate of gas and the liquid flow rate is directly proportional to the value of KGa. The liquid flow rate variable 5 liters / minute, gas flow rate 15 l / min obtained value of KGa 11,1102 at concentration of MSG 5%. Keywords:  Absorption, CO2,  K2CO3, MSG.

Abstract

Pada umumnya pembuatan biodiesel menggunakan etanol dengan kadar 99.8% (pure analitis) yang  membutuhkan biaya tinggi. Penelitian ini dilakukan untuk mempelajari pengaruh ratio mol mnyak sawit dengan etanol konsentrasi rendah terhadap yield dalam pembuatan biodiesel. Ratio mol antara minyak sawit dan etanol yang digunakan dalam pembuatan biodiesel ini adalah 1:12; 1:14; 1:16 dengan waktu reaksi 3 jam dan pemanasan dilakukan pada suhu 60 oC. Proses selanjutnya adalah pemisahan dan pencucian. Berdasarkan hasil analisa, diperoleh bahwa biodiesel yang dihasilkan memenuhi standar SNI-04-7182-2006. Yield terbesar diperoleh pada kondisi waktu reaksi 3 jam, ratio mol 1:16 yaitu 59.26%.

Abstract

One of the water treatment techniques is coagulation. Moringa Oleifera nut as natural coagulant is widely utilized in the process of water purification. Accordingly, the objective of the research was to identify the effect of Moringa Oleifera nut and Phospocarpus tetragonolobus nut powderas natural coagulantto decrease the contents of the total Susupended Solid (TSS), COD, BOD and pH in Domestic laundry waste. The research was initialized by pouring 1 liter of domestic laundry waste water in a basin. Next, it was added with moringa oleifera and Phospocarpus tetragonolobus nut powders in 60 mesh as much as 4 gram with ratios between the moringa oleifera and Phospocarpus tetragonolobus nut powder of 4:0, 3:1, 2:2, 1:3 and 0:4 into the samples. Next, it was stirred by means of jar test instrument with 100 rpm speed for 5 minutes. The samples were precipitated for 30, 60, 90 minutes. Then it was proceeded with filtrate test with parameters of pH, COD and TSS. Based on the research findings it was concluded that application of biocoagulant, i.e. moringa oleifera and Phospocarpus tetragonolobus nut powders did not significantly affect the pH and COD as the value of the pH was arround still 9. The best COD value was attained in 3012 mg/ l by 90 minute precipitation and application ratio between themoringa oleifera and Phospocarpus tetragonolobus nut powder of 4:0. The lowest pH, i.e. : 9,16 was attained by 90 minute precipitation and application ratio between the moringa oleifera nut powder and Phospocarpus tetragonolobus nut powder of the 4:0.
