Abstract

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%. DOI : https://doi.org/10.33005/tekkim.v12i1.836

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

Dalam Penelitian ini dilakukan pembuatan biogas dari jerami yang telah diberikan perlakuan awal, yaitu dengan proses hidrothermal pada kondisi alkaline. Tujuan Penelitian ini adalah untuk meningkatkan produksi biogas dari jerami dengan perlakuan awal tersebut. Proses hidrothermal akan memutus rantai polisakarida karena perlakuan pemanasan dengan dibantu bahan kimia. Prinsip proses hidrothermal adalah degradasi fisik dan kimia dalam autoclave pada suhu 120oC dengan NaOH 3% selama 1 jam. Hasil proses hidrothermal ini sebagai masukan pada digester anaerobik dengan waktu tinggal hidrolik antara 15 – 25 hari. Biogas akan terbentuk dari digester, diukur volumenya dan dihitung potensi pembentukannya setiap kilogram jerami. Digester anaerobik bekerja secara semikontinu, memiliki volume kerja 10 liter dan dengan konsentrasi solid di dalam feed antara 3-12% Hasil penelitian menunjukkan bahwa proses hidrothermal pada perlakuan awal jerami padi akan meningkatkan produksi biogas dibandingkan produksi biogas dari jerami tanpa perlakuan awal secara signifikan. Perlakuan awal hidrothermal mampu meningkatkan produksi biogas 165% lebih tinggi daripada jerami tanpa perlakukan awal. Jerami padi yang tidak dipretreatment hydrothermal mampu menghasilkan biogas 76.3 liter biogas per kilogram jerami kering, sedangkan jerami padi dengan pretreatment hidrothermal mampu menghasilkan 202 liter biogas per kg jerami kering

Abstract

Pada umumnya gas alam (natural gas) yang baru keluar dari perut bumi memiliki kandungan uap air yang cukup tinggi dalam kondisi saturated (jenuh). Kandungan air yang tinggi akan menyebabkan kemungkinan timbulnya hidrat semakin besar sehingga gas tersebut menimbulkan permasalahan dalam operasional pabrik dan dapat menurunkan nilai jual secara ekonomis. Kandungan air harus dihilangkan sampai potensi pembentukan hidrat didalam gas serendah mungkin. Penurunan kandungan air dalam gas ini akan meningkatkan nilai kalori gas tersebut, juga memudahkan dalam pengoperasian gas dan mencegah kerusakan peralatan operasional (Saka Energi Muriah Limited, 2020). Gas dehydration unit dan TEG Regeneration unit memiliki desain awal dengan gas umpan maksimum sebesar 145 MMSCFD, akan tetapi saat ini rate gas maksimum hanya 20 MMSCFD saja. Penelitian ini mengkaji optimalisasi Glycol Dehydration Unit yang efektif pada desain dengan kapasitas yang besar tetapi bisa di andalkan dan beroperasi baik pada kondisi rate gas jauh di bawah desainnya hingga ke batas minimumnya. Optimalisasi dilakukan sampai menemukan kesetimbangan baru di unit Glycol Dehydration dan dapat meningkatkan nilai kalori nantinya. Kata kunci: glycol dehydration, gas processing, proses pemurnian gas, blok muriah, lapangan Kepodang

Abstract

Aluminium foil waste increases every year in line with technology development, especially in the food and beverage industry. It will cause significant environmental problems because the packaging cannot be destroyed in the soil. Therefore, it is necessary to reprocess a large amount of aluminium waste into an alternative product such as alum which can be applied directly to the treatment of liquid tofu waste. In this study, uncoated aluminium foil waste was used, which was taken at random landfill sites and then washed and cut into small pieces. Dissolution of aluminium using KOH solution then the solution obtained is reacted with H2SO4 solution and the reaction is carried out at a temperature of 70oC. The experimental results got a maximum yield of 63.69% with Al2O3  content of 15.18% using 3 M KOH concentration and 5 M H2SO4 concentration. The obtained alum was then applied to the tofu industrial liquid waste. With the use of 800 ppm alum, there was a 60% decrease in the colour content of the Pt-Co unit, a 95.8% decrease in NTU and a 63.33% decrease in TDS. The quality of the liquid waste obtained met the technical requirements of raw water that can be treated by SNI 6773: 2008.
