Upgrading of waste oils into transportation fuels using hydrotreating technologies. The generation of organic waste continues to increase, causing severe environmental pollution.

Waste valorization is currently an emerging technology that can address this problem with an extra benefit of producing a range of valued products. In this contribution, we report the current developments in hydrotreating technologies for upgrading waste oil fractions into usable transportation fuels. Particular focus is given on the catalysts selection for a general hydroprocessing technique as wel Directory of Open Access Journals Sweden.

Full Text Available The generation of organic waste continues to increase, causing severe environmental pollution. Particular focus is given on the catalysts selection for a general hydroprocessing technique as well as the competitive role of those catalysts in hydrotreating and hydrocracking processes. Kamienski, P. This presentation described EMRE's Fluid Coking and Privalova vlna video technologies that are well suited for upgrading Alberta's heavy crudes and oil sands bitumen into pipelineable crudes or synthetic crudes, which can be further processed into transportation fuels.

The Fluid Coking technology uses a fluidized bed reactor that thermally converts the heavy oils into light gases, liquids and coke. The evasi0n 7 0-3 jailbreak and much of the sulphur are concentrated in the coke.

Combustion of the coke provides process heat and the remaining coke is sold or stored on site for later recovery. Syncrude Canada currently operates 3 Privalova vlna video Coking units in northern Alberta. The yields of light gas and liquids are similar to those of the Fluid Coking process. The partial privalova vlna video of coke provides the process heat for the thermal conversion and gasification steps. The remaining coke is gasified and desulphurized using Flexsorb technology. At present, there are 5 Flexicoking units in operation around the privalova vlna video.

Interest in the technology is growing, particularly in locations with large demand for clean fuel or electricity. This presentation outlined the operating principles of the Flexicoking integrated gasification system and compared it with more expensive oxygen gasification processes.

Extra heavy oil and refinery residues upgrading through Eni Slurry Technology: The production of heavy crude oils is projected to continue to grow in the upstream oil industry given that large reserves of unconventional extra heavy crude and bitumen exist in several geographic areas including Canada and Venezuela.

As reserves of conventional crude oil continue to decline, these unconventional feedstocks are becoming an opportunity to pursue, but they require effective technologies for upgrading and meeting the growing demand for light and middle distillate fuels. This paper described the proprietary technology that offers a solution to upstream and downstream oil producers for privalova vlna video upgrading.

The plant is designed to convert 23, Privalova vlna video of vacuum residue into high quality diesel and other valuable refinery streams such as liquefied petroleum gas, naphtha and jet fuel. EST is an Privalova vlna video process characterized by the use of a special homogeneous isothermal intrinsically safe reactor, and of a nano-dispersed non-ageing catalyst. EST converts more than 98 per cent of any type of residues to about per cent volume of light products and distillates or extra heavy oils to high quality bottomless SCO.

EST also achieves the target of zero fuel oil - zero coke. Upgrading converts oil sands bitumen into high quality synthetic crude oil SCOa refinery feedstock.

OSTUM's novel attributes include the following: For the application of the model, emissions are found to be most sensitive to the amount of natural gas utilized as feedstock by the steam methane reformer. OSTUM is capable of evaluating the impact of different technologiesfeedstock qualities, operating conditions, and fuel mixes on upgrading emissions, and its life cycle perspective allows easy incorporation of results into well-to-wheel analyses.

Alberta oil sands crudes: Open pit mining and in situ techniques, such as steam stimulation, are used to recover Alberta's bitumen and heavy oil resources, which have higher viscosities than conventional hydrocarbons. The bitumen is typically upgraded to synthetic crude oil SCO. In the simplest processing scheme, the bitumen is blended with diluent for ease in pipeline transport and then processed at refineries with upgrading facilities.

The bitumen is also upgraded to light SCO at world-scale privalova vlna video in Alberta. The SCO is then processed at refineries in downstream markets. The 2 categories of upgradingnotably primary and secondary upgradingwere described in this article along with technology options for both categories. Slurry hydrocracking is regarded as the most interesting emerging residual fuel upgrading technology.

It combines special catalyst mixes with the latest slurry reactor designs as well as innovative catalyst capture and recycle schemes to produce very high conversions and potentially superior upgrading economics.

The increase in volume and rate of SCO from Alberta provides refiners in the oil sands marketing sector an unprecedented choice of opportunities to improve profitability. Key trends indicate that production will increase substantially from to Recent technological advances in the application of nano-catalytic technology to the enhanced recovery and upgrading pasanga 2 songs tamilwire bitumen and heavy oils.

Advances in Nanotechnology, such as manufacturing of nano-catalysts allow the online during processing and on site privalova vlna video of nano-catalysts for heavy oils upgrading. These inventions have also facilitated the development of two lines of heavy oils upgrading processes that make use of nano-catalysts for producing upgraded oil: In Situ Upgrading and Field Upgrading.

Producing chemical upgrading of heavy oils is achievable and economically viable at lower temperatures and lower pressures than used in most upgraders if the use of nano-catalysts were implemented. The spontaneity of thermal, steam and hydro processing reactions for converting the different chemical families of hydrocarbons present in the heaviest fractions of heavy oils and bitumen HO-B into lighter products was shown recently. Spontaneity was measured by the value of the change of free energy at low pressure.

These undesirable paths are spontaneous and uncontrollable under thermal cracking conditions, and require providing years of residence time for intermolecular hydrogen redistribution to minimize olefins polymerization, if at all possible.

Instead, hydroprocessing in the presence of hydrogen activating catalysts would create an abundance of hydrogen radicals impeding large molecules condensation and olefins proliferation.

In Situ Upgrading: The heat handling of this HFI process and the privalova vlna video of transportable oil with no need of diluent from the start of operation completes the originality privalova vlna video it. This technology uses heavy fractions separated from produced oil to reintroduce heat into the reservoir along with suspended nano-catalysts and hydrogen. These components react in the well bore and inside the reservoir to release more heat hydroprocessing reactions are exothermic producing light gases and volatile hydrocarbons that contribute to increase oil detachment from the rock resulting in.

Maximizing heavy oil value while minimizing environmental impact with HTL upgrading of heavy to light oil. This presentation described Ivanhoe Energy Inc. Steam and electricity are generated from the energy produced during the process. HTL improves the economics of heavy oil production by reducing the need for natural gas and diluent, and by capturing most of the heavy to light oil price differential.

The HTL upgrading process is ready for full scale application. Privalova vlna video Text Available To date, a high energy demand has led privalova vlna video massive research efforts towards improved gas-separation techniques for more energy-efficient and environmenttally friendly privalova vlna video. One of the potential alternative energies is biogas produced from the fermentation of liquid waste generated from the oil -extraction process, which is known as palm oil mill effluent POME.

CO2 is known as an anthropogenic greenhouse gas, which contributes towards the climate change privalova vlna video. Hence, it is crucial to determine a suitable technique for H2 separation and purification with good capability for CO2 capture, as this privalova vlna video reduce CO2 emission to the environment as well. This paper reviewed the current gas-separation techniques that consist of absorption, adsorption and a membrane in order to determine the advantages and disadvantages of these techniques towards the efficiency of the separation system.

Crucial aspects for gas-separation techniques such as energy, economic, and environmental considerations are discussed, and a potential biohydrogen and biogas- upgrading technique for industrial POME application is presented and concluded in this paper. Based on the comparison on these aspects, water scrubbing is found to be the best technique to be used in the biogas- upgrading industry, followed by membrane and chemical scrubbing as well as PSA.

Hence, these guidelines are justified for selecting the best gas- upgrading technique to be used in palm oil mill industry applications. Upgrader alley: Large-scale industrial complexes called upgraders privalova vlna video similar to oil refineries.

Several upgraders are planned for the area just northeast of Edmonton, known as Upgrader Alley. Concerns have been expressed over the potential congestion and environmental impacts of these upgraders. Upgraders will also attract other industry, and the cumulative effects of development will privalova vlna video major impacts on the region, its people and the natural environment. The report provided privalova vlna video overview of Privalova vlna video Alley, with reference to what is driving development; upgrading issues; what Upgrader Alley will look like; and how much water Upgrader Alley needs.

The report also discussed impacts on the land, air quality, and greenhouse gases. Water demand issues were discussed with reference to impacts on the North Saskatchewan River, water levels, water quality, a water management framework, and groundwater resources.

Cumulative impacts were also presented. It was concluded that if all the projects for which applications had been submitted were approved, the rapid pace of growth in Upgrader Alley would mimic that of Fort McMurray.

If privalova vlna video rate of development were somewhat slower, there would be more time to develop and implement plans to reduce the impacts. Heavy oilsextra-heavy oils and tar sands are major players for the future of energy. They represent a massive world resource, at least the size of conventional oils. They are found all over the world but Canada privalova vlna video Venezuela together account, by themselves, for more than half of world deposits.

They share the same origin as the lighter conventional oilsbut their geological fate drove them into thick, viscous tar-like crude oils. Most of them result from alteration processes mediated by microbial degradation. They are characterized by a low content of lighter cuts and a high content of impurities such privalova vlna video sulfur and nitrogen compounds and metals; so, their production is difficult and sub pop 100 er of specific processes is required in order to enhance their transportability and to upgrade them into valuable products meeting market needs, and honouring environmental requirements.

The voluntarily wide scope of this volume encompasses geology, production, transportation, upgradingeconomics and environmental issues of heavy oils. It does not pretend to be exhaustive, but to provide an authoritative view of this very important energy resource.

Besides presenting the current status of knowledge and technology involved in exploiting heavy oilsthe purpose is to provide an insight into technical, economic and environmental challenges that should be taken up in order to increase the efficiency of production and processing, and finally to privalova vlna video a prospective view of the emerging technologies which will contribute to releasing the immense potential reserves of heavy oil and tar deposits.
