Abstract

Oil is a non-renewable natural resource derived from petroleum. PT ALP Petro Industry is an industry that processes used oil back into new oil using vacuum distillation. The purpose of this study is to determine the outlet furnace temperature in optimizing each oil product by using the main pump, furnace, distillation column, exchanger, and tank. This research used vacuum distillation methodology by determining the temperature of the outlet furnace so that it gets the optimal oil product yield. This study uses a fixed variable used oil of raw material with a maximum water content of 0.1% and the flow rate of feed 4000 kg/h and uses a variable temperature of 376°C, 377°C, 378° C, 379°C, 380°C in the furnace outlet. The results showed that at outlet furnace temperature 376°C the yield of SLF oil products was 8.4%, LLF 35.0%, and HLF 16.6%. At temperature 377°C the SLF product yield was 12.2%, LLF 38.0%, and HLF 14.4%. At temperature 378°C the yield of SLF products was 14.9%, LLF was 40.8%, and HLF was 11.5%. At temperature 379°C the yield of SLF products was 15.6%, LLF 42.0%, and HLF 11.4%. At temperature 380°C the yield of SLF products was 16.3%, LLF 43.5%, and HLF 11.0%. Different outlet furnace temperatures produce different oil product yields because each fraction has different boiling points. The higher the outlet furnace temperature, the lower the HLF fraction oil product yield, and the higher LLF and SLF oil product yield. The lower the outlet furnace temperature, the higher the HLF oil product yield, and the lower LLF and SLF oil product yield.

Abstract

n-Butanol is one of the intermediate materials used as raw material for downstream industries such as the textile, polymer, plastic, paint, surface coating, pharmaceutical, and others industries. There are several methods that can be used in the manufacture of n-Butanol, one of which is the hydrogenation process, where the raw material butyl butyrate is reacted with hydrogen gas in a Fixed Bed Multitube Reactor using a solid catalyst to produce n-Butanol. The n-Butanol plant is designed with a capacity of 5,000 tons/year. The factory operates 330 days a year, with a production process of 24 hours/day. The reaction occurs in the gas phase with a temperature of 280°C and a pressure of 10 atm, the reaction is exothermic using a Cu/ZnO/Al2O3 catalyst with a mole ratio of reactant butyl butyrate and hydrogen of 1:14 and produces a product conversion of n-Butanol of 90%. Further purification was carried out using a distillation tower in the form of n-Butanol with a purity of 99.50%. The device is designed in the form of a heater that functions as a hydrogen heater from a temperature of 30°C to 280°C before being sent to the reactor. The heating medium used is steam from the boiler. Hydrogen flowing in the heater with a capacity of 119.44 kg/hour and after calculations, obtained a heater of the double pipe heat exchanger (DPHE) type, pipe dimensions 21/2 inch x 11/4 inch with 3 hairpins, pipe length 20 ft. the annulus flows hydrogen and the pipe flows steam as a heater. The heater uses a construction material in the form of carbon steel.

Abstract

ABSTRAK Biodiesel adalah bahan bakar mesin diesel yang tesusun dari ester alkil asam lemak. Biodiesel dihasilkan dengan mereaksikan minyak nabati dengan alkohol melalui reaksi trans-esterifikasi berkatalis dengan hasil samping gliserol. Pada penelitian yang dilakukan proses produksi menggunakan reaktor kontinyu (Plug Flow Reactor) yang telah dirancang dimana proses pencampuran dan pengadukan antara bahan baku utama biodiesel dengan katalis berlangsung secara terus-menerus dengan selang waktu dan suhu tertentu.. Di dalam reaktor yang dirancang terdapat baffle atau pengaduk. Pengaduk ini berfungsi untuk memperluas kontak permukaan dan menghasilkan turbulensi yang tinggi sehingga dapat mencegah tube bergetar. Plug Flow Reactor digunakan karena memiliki efisiensi yang tinggi dibandingkan Reactor Alir Tanpa Pengaduk. Untuk menguji alat yang telah dibuat dilakukan penelitian dengan bahan baku minyak biji randu yang direaksikan dengan methanol dan katalis basa (KOH). Minyak biji randu dimanfaatkan sebagai bahan baku karena merupakan minyak non pangan yang memiliki kemampuan untuk dirubah menjadi biodiesel. Variabel yang diberikan adalah suhu reaksi 40oC, 50oC dan 60oC. Karakteristik biodiesel terbaik dari minyak biji randu dihasilkan pada variabel ratio mol methanol terhadap mol minyak 6:1 dengan suhu 600C yaitu: % FAME 95.70 %, berat jenis 0.882gr/ml, dan titik nyala 1360C. Kata kunci : Biodiesel, PFR berbaffle, transesterifikasi ABSTRACT Biodiesel is a fuel for diesel engines consisting of alkyl esters of fatty acids. Biodiesel is made by reacting vegetable oil with alcohol through trans-esterification reaction with a compound katalis esters with glycerol by product. Instudies conducted using a production process of continuous reactors(Plug Flow Reactor) which has been designed in which the process of mixing and stirring among the main biodiesel feed stock with the catalyst takes place continuously with specific time and temperature. Inside the reactor are designed with baffle. Baffle serves to expand the contact surface and obtain high turbulence, so that can prevent the occurrence of vibration on the tube. Plug Flow Reactor has more efficiency than Flow Reactor Without Baffle. To test the tool that was created to do research with kapok seed oil feed stock is reacted with methanol and base catalyst(KOH). Kapok seed oil used by raw material because kapok seed oil as non – food oil is potentially for biodiesel synthesis. Variables given the reaction temperature is40oC, 50oC and 60oC. The best characteristics of kapok seed oil is perduced at variable mol ratio of 6:1methanol to oil mol and amount of catalist 1 % and temperature 600C namely:% FAME 95.70 %, density of 0.882gr/ml, and flash point of 1360. Key words: Biodiesel; PFR with baffle; Transesterification
