Bitumen - The Archaeology and History of Black Goo Bitumen is the thickest form of petroleum there is, made up of 83% carbon, 10% hydrogen and lesser amounts of oxygen, nitrogen, sulphur, and other elements. It is a natural polymer of low molecular weight: at lower temperatures it is rigid and brittle, at room temperature it is flexible, at higher temperatures it flows.

- Some of the bitumen in Syria was found to have originated from the Hit seepage on the Euphrates River in southern Mesopotamia. The earliest reed boat discovered yet was coated with bitumen, at the site of H3 at As-Sabiyah, about 5000 BC.And, one of the myths of the Mesopotamian Sargon the Great of Akkad was that as an infant he floated in a bitumen-coated reed basket down the Euphrates River.he earliest reed boat discovered yet was coated with bitumen, at the site of H3 at As-Sabiyah, about 5000 BC.

Polymer-modified bitumen sheet membranes There are two types of MB roofing membranes: SBS polymer-modified bitumen membranes commonly are installed in hot moppings of asphalt (similar to BUR systems) or cold adhesive. Some SBS modified membranes are self adhering; that is, they contain an adhesive backing.

About Oil Shale Oil shale. The term oil shale generally refers to any sedimentary rock that contains solid bituminous materials (called kerogen) that are released as petroleum-like liquids when the rock is heated in the chemical process of pyrolysis.il shale can be mined and processed to generate oil similar to oil pumped from conventional oil wells; however, extracting oil from oil shale is more complex than conventional oil recovery and currently is more expensive. The oil substances in oil shale are solid and cannot be pumped directly out of the ground.

Bituminous coal Bituminous coal is an organic sedimentary rock formed by diagenetic and sub metamorphic compression of peat bog material. Its primary constituents are macerals: vitrinite, and liptinite. The carbon content of bituminous coal is around 60–80%; the rest is composed of water, air, hydrogen, and sulfur, which have not been driven off from the macerals.

What Is Bitumen (Asphalt)? Today the world’s demand for bitumen accounts for more than 100 million tons per year which is approximately 700 million barrels of bitumen consumed annually. Petroleum bitumen is typically referred to as bitumen or asphalt.In Europe for instance bitumen means the liquid binder. In North America, on the other hand the liquid binder is referred to as asphalt, or asphalt cement.oday the world’s demand for bitumen accounts for more than 100 million tons per year which is approximately 700 million barrels of bitumen consumed annually.

Upgrading The Syncrude upgrading process converts the thick bitumen into a high quality, light, low sulphur crude oil. The first step in the upgrading process is to remove the naturally occurring light gas oil component of bitumen and to recover the diluent naphtha. This is done in the three diluent recovery units, which operate much like an atmospheric distillation unit in a conventional refinery.

- Lower grade coal is estimated to represent 75% to 80% of all petcoke produced. The production of petcoke in North America has increased in recent years due to the refining of crude oil originating from Canada’s tar sands region.If all the recoverable bitumen (the “proven reserves”) from tar sands was removed and refined, several billion tons of petcoke could be produced.he production of petcoke in North America has increased in recent years due to the refining of crude oil originating from Canada’s tar sands region.

- On the other hand, bitumen with low penetration grade or hard bitumen has less low temperature cracking but more rutting resistance [ 1, 2 ]. This alteration can be related to the complex rheological behavior of bitumen at different loading times and temperatures [ 3, 4 ].n the other hand, bitumen with low penetration grade or hard bitumen has less low temperature cracking but more rutting resistance [ 1, 2 ].

About Tar Sands The bitumen in tar sands cannot be pumped from the ground in its natural state; instead tar sand deposits are mined, usually using strip mining or open pit techniques, or the oil is extracted by underground heating with additional upgrading. See the Photos page for additional photos of tar sand and tar sand mining.

How Oil Refining Works It is also known as petroleum. Crude oil is a fossil fuel, meaning that it was made natural­ly from decaying plants and animals living in ancient seas millions of years ago -- most places you can find crude oil were once sea beds.Crude oils vary in color, from clear to tar-black, and in viscosity, from water to almost solid.To see examples of the structures of these types of hydrocarbons, see the OSHA Technical Manual and this page on the Refining of Petroleum. Now that we know what's in crude oil, let's see what we can make from it.

About Tar Sands Tar sands are mined and processed to generate oil similar to oil pumped from conventional oil wells, but extracting oil from tar sands is more complex than conventional oil recovery. Oil sands recovery processes include extraction and separation systems to separate the bitumen from the clay, sand, and water that make up the tar sands. Bitumen also requires additional upgrading before it can be refined. Because it is so viscous (thick), it also requires dilution with lighter hydrocarbons to make it transportable by pipelines.

Asphalt The largest use of asphalt/bitumen is for making asphalt concrete for road surfaces and accounts for approximately 85% of the asphalt consumed in the United States. Asphalt concrete pavement mixes are typically composed of 5% asphalt/bitumen cement and 95% aggregates (stone, sand, and gravel).he asphalt/bitumen in the removed material can be reactivated and put back to use in new pavement mixes. With some 95% of paved roads being constructed of or surfaced with asphalt, a substantial amount of asphalt pavement material is reclaimed each year.

Petroleum Coke: The Coal Hiding in the Tar Sands 1 There is 24 percent more CO2 embedded in a barrel of tar sands bitumen than in a barrel of light oil. 2  15 to 30 percent of a barrel of tar sands bitumen can end up as petcoke, depending on the upgrading and refining process used. 3  Of 134 operating U.S. refineries in 2012, 59 are equipped to produce petcoke.ut as bad as these impacts already are, existing analyses of the impacts of tar sands fail to account for a byproduct of the process that is a major source of climate change causing carbon emissions: petroleum coke – known as petcoke.

What is Bitumen? You won't believe these 10 facts about people. Bitumen may refer to either a naturally occurring mixture of various organic liquids, also called crude bitumen, or a residue yielded in the distillation process of coal or petroleum, called refined bitumen.his process produced materials such as bitumen. Natural deposits can be found all over the world, with the largest located in Canada and Venezuela. Historical usages of bitumen can be traced back 8,000 years with its presence in various Neanderthal tools.
