In this study, the energy consumption in the food and beverage industries of Iran was investigated. The energy consumption in this sector was modeled using artificial neural network (ANN), response surface methodology (RSM) and genetic algorithm (GA). First, the input data to the model were calculated according to the statistical source, balance-sheets and the method proposed in this paper. It ...

Hydrocarbons are ubiquitous in daily life and include plant and animal fats, alcohols, solvents, natural gas, petroleum derivates. Majority of intoxication reports of hydrocarbons are due to inhalation or ingestion, but there is few reports about intravenous injection of gasoline. We report a 58 year-old man who injected gasoline intravenously for suicide. He developed soft tissue necrosis of f...

The effect of gas flaring involving some areas of the Niger Delta in Nigeria has been successfully carried out. Four villages were considered under this work: Aghigho, Obagi, Imeh and Edikan. An analysis of the volume of carbondioxide produced in each of the villages was carried out. The results of the analysis revealed that the effect of flaring associated gas on the environment is high based ...

In an effort to reduce dependence on petroleum-based fuels and increase engine efficiency, fuel-flexible engines with advanced technologies, including variable valve timing, are being developed. Fuel-flexible spark-ignition engines permit the increased use of ethanol–gasoline blends. Ethanol, an alternative to petroleum-based gasoline, is a renewable fuel, which has the added advantage of impro...

A Y zeolite-containing wide-pore composite was synthesized by in situ technique using polyvinyl alcohol and silica sol material. A fluid catalytic cracking (FCC) catalyst for maximizing gasoline yield was successfully developed with the modified composition. The as-made zeolite Y in its sodium form had a relative crystallinity of 52.9 % with a high silica/alumina amount of substance ratio of 5....

Investigations were conducted to evaluate the performance of a two-stroke, single cylinder, spark ignition (SI) engine, with gasohol (80% gasoline and 20% ethanol by volume) having copper coated engine [CCE, copper-(thickness, 300 μ) coated on piston crown, inner side of cylinder head] provided with catalytic converter with different catalysts of sponge iron and manganese ore and compared with ...

The energy released in a solar flare is partitioned between thermal and nonthermal particle energy and lost to thermal conduction and radiation over a broad range of wavelengths. It is difficult to determine the conductive losses and the energy radiated at transition region temperatures during the impulsive phases of flares. We use UVCS measurements of O VI photons produced by 5 flares and subs...

The Technical University of Madrid (UPM) and REPSOL YPF are collaborating in the improvement in the estimation of the emiss ion factors for refinery flares. Flaring is an unavoidable process in the refining activity, both for safety reasons during upset processes (start-up, shut down, system blow-down) and when managing the disposal of waste gases with hydrocarbon from routine operations. The o...

Alternative fuels, like a mix of pyrolyzed plastic waste and gasoline, have made us less dependent on nonrenewable petroleum. Since HDPE has low density, it is perfect for producing more oil at temperatures as 400oCelsius. It density around 0.94 g/cm3, whereas gasoline between 0.60 g/cm3 0.78 g/cm3. This study compared blend C10 C20 engine speeds 1500, 2000, 2500 rpm to C0 gasoline. Results ind...
