“…The extraction of the soil with methanol and the drying of the solvent at ambient temperature resulted in heavy and highly viscous residue which can be sorted as resinous material. However, the long exposure time of the soil to the heat radiation from the flare and the action of atmospheric oxygen and soil mineral components can account for a catalytic conversion of middle distillates into resinous material [15][16][17]. The soil contamination with hydrocarbons might have adverse effects on cultivation.…”

The environmental site assessment (ESA) of Al-Duara refinery in Baghdad, Iraq. The hydrocarbon content of the soil around this site was measured to evaluate the extent of the organic pollution depending on selected parameters of potential pollution. Soil samples were collected at various depths from almost all locations including: production units, storage tanks, the landfill lagoons at the outside boarder of the refinery and the residence location. For the evaluation of the nature of soil layers, a monitoring well was drilled in the vicinity of a wide dumping area for heavy untreatable materials. Some field tests were carried out to evaluate the hydrocarbonin-soil (Turbidimetric); Laboratory analysis for the soil extracts and types of hydrocarbon pollutants. The soil texture was evaluated using the standard methods to assess any future remediation efforts. It appeared that storage tanks location is among the serious polluting sources via leakage or overflow of the drainage collection channels. The pollution sometimes extended deep in the soil, 80-100 cm. The maintenance and rehabilitation operations contribute much pollution by heavy sludge containing hydrocarbons, mud and inorganic matter. Most of the pollution load is directed towards the wastewater treatment plant. The dumping location and over more than 30 years resulted in deep penetration of hydrocarbons so that the location is considered the most effective source of pollution. Finally, the fall out is a major means of pollution of remote area within the site by heavy hydrocarbons.Recommendations for remediation of the most polluted locations in the site were listed at the end of this study. However, the company is continuously doing actions to remove polluted soil and replace it with clean soil.

Thermal Oxidation Stability of Aviation Turbine Fuels

From the initial observation that thermal oxidation stability of aviation turbine fuels could induce problems in the fuel system, it was realized that the difficulties varied from fuel to fuel. For instance, flight performance in the F100C aircraft operating at the same test conditions varied considerably for five different fuels [1]. After 100-h tests, the decrease in fuel flow into the combustor varied from 2.44 to 18.44%, a 7.5-fold range in behavior. Figure 6 of Chapter V also illustrates the wide response of jet fuels to thermal oxidative stress [2]. In this figure, the deterioration in heat transfer coefficient for three Jet A-1 fuels is shown as a function of fuel outlet temperature from the Shell Research STHTR. At a low fuel-out temperature (210°C), one fuel effects a 25 times greater change in heat transfer than another fuel, but at a fuel-out temperature of 240°C the three fuels exhibit a similar effect on heat transfer.
