Abstract

Crude Distilation Unit (CDU) merupakan unit penting sebelum crude masuk kedalam kolom distilasi maka terlebih dahulu melalui proses desalting di desalter. Desalter merupakan unit yang dioperasikan untuk membersihkan crude oil dari kontaminan seperti, garam-garam mineral, ion-ion terlarut dan solid yang terikut pada saat pengeboran minyak. Kadungan pengotor yang terdapat pada crude oil dapat menyebabkan terjadinya korosi, pemampatan pipa dan lain sebagainya. Jika kadar garam sebagai pengotor melebihi 4ptb (jumlah minimum kadar garam dalam crude) maka crude tidak dapat lanjut ke proses berikutnya di karenakan akan merusak proses. Efisiensi kinerja desalter selama 30 hari menghasilkan angka terbaik, pada tanggal 10 april 2017 yaitu 94,153%. Hal tersebut disebabkan karena pengaruh temperatur, spesific grafity dan density yang baik sehingga hasil efisiensinya optimal

Abstract

Abstrak Sintesis biodiesel umumnya melalui proses transesterifikasi suhu tinggi menggunakan katalis homogen yang membutuhkan energi cukup besar, pemisahan katalis yang cukup sulit dan terbuang sebagai limbah. Sintesis biodiesel metode elektrokatalitik memberi keuntungan efisiensi lebih daripada transesterifikasi suhu tinggi. Pada penelitian ini, sintesis biodiesel metode elektrokatalitik dilakukan menggunakan elektroda grafit suhu 28oC dan tegangan konstan 18,2 Volt. Variabel waktu reaksi selama 60 menit, 120 menit, dan 180 menit, rasio molar minyak – metanol 1:9, katalis BaO/CaO 2% b/b terimpregnasi dengan berat katalis 5% b/b terhadap minyak digunakan untuk mengevaluasi biodiesel yang dihasilkan. Produk biodiesel berupa metil ester asam lemak bebas dianalisis menggunakan GC-MS. Hasil penelitian menunjukkan yield yang dihasilkan dengan waktu reaksi 60 menit, 120 menit, dan 180 menit berturut – turut sebesar 88%, 94%, dan 90 dengan waktu reaksi optimum 120 menit. Dan terdapat empat kandungan utama metil ester di semua waktu reaksi yaitu: metil palmiat, metil oleat, metil linoleat, metil stearat. Karakteristik biodiesel yang dihasilkan dilihat dari nilai densitas, viskositas, dan bilangan asam memenuhi kualifikasi SNI Biodiesel 04-7182-2006. Abstract Synthesis of biodiesel generally uses a transesterification process at high temperature with homogeneous catalyst that requires a large amount of energy, separation of the catalyst is quite, and is wasted as waste. Electrocatalytic biodiesel synthesis method gives more advantages in high temperature transesterification. The reaction time variables were 60 minutes, 120 minutes, and 180 minutes, the oil-methanol molar ratio was 1: 9, the BaO / CaO 2% w / w catalyst was impregnated with a catalyst weight of 5% w / w to the oil used for the resulting biodiesel. The results showed that the results with a reaction time of 60 minutes, 120 minutes, and 180 minutes were 88%, 94%, and 90 minutes respectively with an optimal reaction time of 120 minutes. It showed that there were four main ingredients of methyl ester at all reaction times, namely: methyl palmyate, methyl oleate, methyl linoleate, methyl stearate. The characteristics of the resulting biodiesel seen from the density, viscosity, and acid number have met the SNI Biodiesel 04-7182-2006 qualifications.

Abstract

Corrosion is one of the processes of metal damage or degradation due to redox reactions between a metal and various substances in its environment that produce undesirable compounds. In the water one of the environmental parameters is water resistivity. By knowing the connection between water resistivity and corrosion rate, it is possible to monitor laboratory tests with water environments that have different levels of corrosiveness. Therefore, it is necessary to conduct an analysis to determine the effect of water resistivity on water corrosivity, understand the factors that influence the corrosion rate and calculate the corrosion rate of the irrigation gate steel plate on the water environment. This analysis uses a laboratory scale, analysis with talagasari irrigation water media, domestic wastewater, PDAM water and dead river estuary water. All water media used have a high level of corrosiveness. The factor that causes the low resistivity value is the large amount of inorganic minerals containing metal in the water so that at low resistivity values the corrosion rate increases. In the results of this laboratory analysis, it is proven that the more acidic the water medium, the faster the corrosion rate and the more alkaline the water medium, the slower the corrosion rate.

Abstract

Carbon Steel 1018 is a low carbon steel having a carbon content (C) of 0.14-0.20% (<0.30% C). Low carbon steel is commercially known as mild steel. Corrosion is one way to prevent corrosion caused by the environment. Corrosion inhibitor are taken between the Crude Corrosion Inhibitor and Gas Corrosion inhibitor on Carbon Steel 1018 using the polarization method. Corrosion inhibitors work by making passive layers in the form of thin films or films on the surface of the material used as a barrier between metals and corrosive media. The analysis method used is polarization. Inhibition Efficiency Results obtained for Gas Corrosion Inhibitors (1A) at 10 ppm 96.86%, 20 ppm 59.74%, 30 ppm 74.48%. The Crude Corrosion Inhibitor (2A) results obtained inhibition efficiency for 10 ppm 99.57%, 20 ppm 77.69%, and 30 ppm 12.63%. The optimum value for the Gas Corrosion Inhibitor and Crude Corrosion Inhibitor is at 10 ppm at 96.86% and 99.57%. Keywords: carbon steel,crude corrosion inhibitor, corrosion , gas corrosion inhibitor, inhibitor
