Production, trade and supply of gas oil/diesel oil

The objective of this study was to determine the fuel properties of Sand Apple Ethyl Ester (SAEE) and its blends with Automotive Gas Oil (AGO).using eggshell as catalyst. Sand apple seed oil (SASO) obtained was characterized based on America Society for Testing and Material (ASTM D6751) to determine acid value, saponification, iodine content, density, kinematic viscosity, flash point, cloud point and pour point. Sand Apple fruits were processed and oil extracted using solvent extraction method. Raw eggshells were calcined at 800oC for 120 min in the muffle furnace. SAEE was blended with AGO at 5 – 25 % mix. Data obtained was analyzed using ANOVA at P < 0.05 significant level. Cloud and pour points obtained for SASO are 4.68 and 3.09℃ . Flash point was 103℃ which fell within ASTM D93 range indicating that SASO is safe for handling and storage. Heating value was 42.61 MJ/kg, slightly lower than that of diesel oil of 44.8 MJ/kg shows that AGO has ability to produce heat of combustion than SASO. Iodine value was 80.71 g I/100g while acid value was determined to be 2.62 mgKOH/g, which was higher than that of ASTM D6751 of 0.5 mgKOH/g. Sulphur contents for AGO and SASO–AGO blends were 0.006, 0.009, 0.014, 0.016 and 0.004%, respectively. Low sulphur values indicates that hazardous sulphur dioxide emission of SAEE has reduced. This study established that all the properties obtained, except acid value, fell within the ASTM specification and could suitably be compared with those of fossil diesel.

The paper presents test results carried out with using of CI engine fuelled with diesel oil and synthetic fuels. Research results show that SYNON be used in diesel fuel. Combustion process of such fuel blends depend on mixture composition. Using of SYNON in mixture with diesel oil follows to increase a value of maximum pressure rise in combustion chamber.

Engineering of solar collector and LPG-burner for curing Virginia tobaccoIndonesia produces 30 tones of Hue cured tobacco every year. Curing Virginia tobacco needs I 29 I kerosene per I kg cured leaves, thus lo process 30 tones cured leaves, it needs 38.7 liter kerosene with a value ol Rp 1 5.5 billion per year Kerosene as a source of energy is used for house hold in Ihe village and it is highly subsidized by the government. For such industries as tobacco processing other sources of energy are available, including gas oil, diesel oil and fuel oil, solar energy, coal, and liquid petroleum gas This study was aimed at designing solar collector and LPG buner suitable lor Virginia tobacco flue curing. Tobacco leaves were cured in a curing barn with LPG as a fuel, while the solar collector was installed on Ihe roof of Ihe barn. The size of the curing barn was 4 m x 4 m x 7 m with a capacity of iwo tones fresh leaves. The LPG-burner used was BA'I'/Baliltas-I, with was specially designed for lobacco curing barn ('nring method followed Ihe standard method practiced by farmers The experiment was conducted al IT Sadhana Arif Nusa. Has! Lombok. NTR from Angus! lo September 1997 The rcsull of experiment was evaluated holh from technical and economical aspects. The used of LPG combined with solar collector as the source of energy could reach Ihe required temperatures (J0-70°(.) during curing phases LPG consumption was 0.86 kg/ kg cured leaves, and solar energy contributed 6.48% of total energy required for curing process From economical view, the used of LPG and solar energy was not profitable. This was mainly due to Ihe high prices of LPG (Rp I 000 /kg) LPG-lank (Rp 1 600 000/unit) and roof- solar collector (Rp I 500 000 per unit).
