Title

Hazard Assessment of LNG Loading-Unloading Process in Cirebon Port Hary Devianto; Mitra Eviani; Pramujo Widiatmoko; Isdiriayani Nurdin
Reaktor Volume 18 No. 2 June 2018
Publisher : Dept. of Chemical Engineering, Diponegoro University

Cirebon Port has spacious work and water area that provides opportunities to be developed in industrial sectors, particularly the petrochemical industries such as ethylene and Liquefied Natural Gas (LNG). In atmospheric condition, they are classified as volatile gas. Either in processing or transporting, they are stored in closed system. However, they still have a probability to be released to the environment and may lead to a fire or explosion. This probability is increased in the existence of coal stockpile in the port area which can evoke a fire. Therefore, a safety study is needed to identify the risk of the loading-unloading activities. The problem was solved by following steps. First, the data such as physical properties, layout area, and geographical condition around the port were collected. Then, the hazardous nodes were identified qualitatively, and then the quantitative analysis was done using As Low As Reasonably Practicable (ALARP) analysis. From the safety study, a suitable handling and safety system is provided to ensure safety viability in the ethylene and LNG loading-unloading process at the Cirebon port.Keywords: ethylene; hazard assessment; LNG; loading-unloading process; Quantitative Risk Assessment (QRA)

One of dye sensitized solar cell’s (DSSC) component is conductive glass, a transparent glass substrate covered with semiconductor oxide, usually fluorine-doped tin oxide (FTO). An economic and scalable method used to deposit the FTO film is spray pyrolysis. A research conducted by Fukano et al. (2004) showed that introducing intermittence in spray pyrolysis using batch atomizer improves the glass’ characteristics. This research aims to observe the effect of intermittence on spray pyrolysis method using nebulizer. A compressor nebulizer and hotplate were used, where the glass’ surface temperature reached 300oC. Transmittance, conductance, morphology and composition of the glasses produced were analyzed. Deposition time and intermittence were varied. Variation of time were 5; 7.5; 10; 16; and 39 minutes. Deposition time of 7.5 minutes showed the highest figure of merit (FOM) of 7.83×10-3 Ω-1. Intermittence was performed by turning the nebulizer off during deposition, with varying period and amount of intermittence. Periods of intermittence were varied for 10, 20, and 30 seconds, and amounts of intermittence were varied 1, 2, and 3 times. Variation of 3 intermittences at 20 seconds each resulted in the highest FOM of 19.29×10-3 Ω-1. DSSC’s efficiency built using produced conductive glass are 1.9×10-4 % and 5.5×10-4 %.

EFFECT OF ANODES TYPES ON NICKEL RECOVERY FROM SYNTHETIC ELECTROPLATING WASTE ELECTRODEPOSITION CELLS. A study concerning the recovery of nickel from electroplating wastewater artificial solution. The study was conducted with a batch system using electrodeposition cell consisting of two spaces separated by water hyacinth leaf, copper cathode plate, H2SO4 solution anolyte, catholyte solution of NiSO4 plus NaCl supporting electrolyte and anode varied. Electrodeposition performed at the direct current of 5V power for 4 hours each run. The research objective was to obtain the best anode in nickel electrodeposition process of electroplating waste artificial solution. Graphite, stainless steel type AISI 316 and the lead were used as a variation of the anode. Concentration of nickel in the catholyte at baseline 2200 mg/L. The results showed that the anode was a graphite anode with best value decreased by 72.44% nickel concentration, deposition of nickel on the cathode of 0.188 grams and specific energy values of 6.1625 kWh/kg.nickel. Telah dilakukan penelitian tentang pemulihan logam nikel dari larutan tiruan air limbah electroplating. Penelitian dilakukan dengan sistem batch menggunakan sel elektrodeposisi yang terdiri dari dua ruang yang dipisahkan dengan daun eceng gondok, katoda pelat tembaga, anolit larutan H2SO4, katolit larutan NiSO4 ditambah elektrolit pendukung larutan NaCl dan anoda divariasikan. Elektrodeposisi dilakukan pada listrik searah sebesar 5V selama 4 jam setiap tempuhan. Tujuan penelitian adalah memperoleh anoda terbaik pada proses elektrodeposisi nikel dari larutan tiruan limbah electroplating. Grafit, Stainless Steel tipe AISI 316 dan timbal digunakan sebagai variasi jenis anoda. Konsentrasi nikel dalam katolit pada awal penelitian 2200 mg/L. Hasil penelitian menunjukkan bahwa anoda grafit merupakan anoda yang paling baik dengan nilai penurunan konsentrasi nikel sebesar 72,44%, deposisi nikel di katoda sebesar 0,188 gram dan nilai energi spesifik sebesar 6,1625 kWh/kg.nikel.
