This work presents a simulation approach to the design and economic evaluation of fuel oil hydrotreating processes for the control of SO2 and NOx emission in an Iranian steam power plant. The percent of fuel oil desulphurization was estimated from the SO2 emissions standards for power plants. Based on two different scenarios according to (I) European and (II) Iranian standards, the design and s...

Abstract—Five palm oil ether monoesters utilized as novel biodiesels were synthesized and structurally identified in the paper. The investigation was made on the effect of ether species on physicochemical properties of the palm oil ether monoesters. The results showed that density, kinematic viscosity, smoke point, and solidifying point increase linearly with their –CH2 group number in certain ...

Four years ago, as the temperature of rhetoric in the food-versus-fuel debate rose with the prices of corn and oil, Farm Foundation asked three economists from Purdue University to take an objective look at the complex forces that were driving food prices. While oil prices are not at 2008 levels this summer, drought and high temperatures are pushing corn and soybean prices to record levels, and...

Could propane from Alaska’s North Slope reduce energy costs for electric utilities and residential space heating, water heating, and cooking demands? We explored the hypothesis that propane is a viable alternative for fourteen selected communities along the Yukon and Kuskokwim Rivers, coastal Alaska, and Fairbanks. Our analysis forecasts propane and fuel prices at the wholesale and retail level...

Production of electricity by burning coal, oil, and natural gas produces CO2, SO2, NOx, etc. which act as greenhouse gases and pollutants. This paper examines fuel use, energy production, and the quantities of these gases produced in the Malaysian economy during the years 1991 and 2000. Input-output (Leontief) analysis is used in this study to enable calculation of energy demand and pollution e...

Belite cement was prepared using nano-silicas extracted from three different agricultural wastes – black rice husk ash (BRHA), bagasse (BA), and palm oil fuel (POFA) which were reacted at 1200 − 1400 °C with CaC2 residue as calcium source. The product compared that CaCO3. Nano-silica BRHA of very fine particle size (surface area 312.4 m2/g V/S ratio 0.35 × 106 cm) being highly reactive, forms β...

The study was done on Jatropha bio fuel stove technology. The study deals with comprehensive literature review followed by technical modifications. The wick stove proto type designed for kerosene burning was chosen for the study. The concepts for preliminary design and premodifications were drawn on the basis of observations received during testing of proto type to burn with Jatropha oil. Then ...

Worldwide concerns about sulfur oxide (SOx) emissions from ships are motivating the replacement of marine residual oil (RO) with cleaner, lower-sulfur fuels, such as marine gas oil (MGO) and marine diesel oil (MDO). Vessel operators can use MGO and MDO directly or blended with RO to achieve environmental and economic objectives. Although expected to be much cleaner in terms of criteria pollutan...

The new requirements for sulfur content in liquid fuels demand the use of novel deep desulfurization processes. 4-methyldibenzothiophene, 4,6dimethyldibenzothiophene and their alkyl-substituted derivatives are the key substances that need to be separated from diesel fuel and fuel oil. These compounds require higher hydrogen consumption in the hydrodesulfurization process and the use of addition...

In the EU countries a system is in place for marking and coloring fuel to distinguish different fuel tax class. Fiscal marker present in fuel does not change the color of fuel and it is determined by the reference method for the determination of the European Union euromarker (Solvent Yellow 124) in gas oil (method of high performance liquid chromatography, HPLC with detection by UV / DAD) 1. By...
