Oil Formation

The abundance of plastic waste is caused by inadequate management. The element of plastic waste consists of crude oil and natural gas that can be reuse as fuel. The conversion technique which can be applied is thermal cracking as known as pyrolysis that combined with a catalyst. The addition of a catalyst can accelerate the process of crude oil formation so that the volume increases and makes the quality better. The pyrolysis can convert waste into oil up to 81% that are consist of paraffin, isopropyl, olefin, naphthal and aromatics so feasible to use as fuel. Keywords: catalyst, crude oil, fuel, plastic waste, pyrolysis.

Abstract The discharge of water from oil fields It has become one of the most significant environmental concerns associated with the oil sector. Hydrocarbon spills and crude oil fuel spills are a continual hazard to aquatic ecosystems. Inexpensive and sustainable sorbent materials are needed to mitigate the environmental damage of this pollution. To meet this need, this study features a low-density polysulfide polymer prepared by Sulfur and used cooking oils react directly. Since both sulfur and cooking oils are hydrophobic, the polymer is close to hydrocarbons such as crude oil and diesel fuel and can easily remove them from seawater. Oil can be recovered and polymer can be reused in oil spill treatment. Polysulfide is unique in that it is prepared from completely recycled waste. Sulfur is a by-product of the petroleum industry, and used cooking oil can also be used as a raw material. Therefore, waste sulfur from the petroleum industry is used to make effective anti-pollution adsorbents from the same sector According to the study’s findings, 98.55 percent of the oil was removed from the north.

The contamination of soil and water with petroleum and its products occurs due to accidental spills during exploitation, transport, processing, storing and use. In order to control the environmental risks caused by petroleum products a variety of techniques based on physical, chemical and biological methods have been used. Biological methods are considered to have a comparative advantage as cost effective and environmentally friendly technologies. Bioremediation, defined as the use of biological systems to destroy and reduce the concentrations of hazardous waste from contaminated sites, is an evolving technology for the removal and degradation of petroleum hydrocarbons as well as industrial solvents, phenols and pesticides. Microorganisms are the main bioremediation agents due to their diverse metabolic capacities. In order to enhance the rate of pollutant degradation the technology optimizes the conditions for the growth of microorganisms present in soil by aeration, nutrient addition and, if necessary, by adding separately prepared microorganisms cultures. The other factors that influence the efficiency of process are temperature, humidity, presence of surfactants, soil pH, mineral composition, content of organic substance of soil as well as type and concentration of contaminant. This paper presents a review of our ex situ bioremediation procedures successfully implemented on the industrial level. This technology was used for treatment of soils contaminated by crude oil and its derivatives originated from refinery as well as soils polluted with oil fuel and transformer oil.

The Impact

The present energy availability and pricing situation has caused many users to consider the use of less refined fuels for combustion gas turbines. The use of these fuels will have a definite impact on the cost of operation and unit availability. It is necessary that a user be aware of the extent of this impact prior to making the decision to convert to a lower quality fuel. This paper discusses the method employed by one user to evaluate this impact and presents the results that were obtained.

Scintillating Fiber

The imaging requirements for 1000 line CCD camera systems include resolution, sensitivity, and field of view. In electronic camera systems these characteristics are determined primarily by the performance of the electro-optic interface. This component converts the electron image into a light image which is ultimately received by a camera sensor.Light production in the interface occurs when high energy electrons strike a phosphor or scintillator. Resolution is limited by electron scattering and absorption. For a constant resolution, more energy deposition occurs in denser phosphors (Figure 1). In this respect, high density x-ray phosphors such as Gd2O2S are better than ZnS based cathode ray tube phosphors. Scintillating fiber optics can be used instead of a discrete phosphor layer. The resolution of scintillating fiber optics that are used in x-ray imaging exceed 20 1p/mm and can be made very large. An example of a digital TEM image using a scintillating fiber optic plate is shown in Figure 2.
