Oil and Petroleum

Crude oil mainly contains hydrocarbons, which are compounds made of hydrogen and carbon atoms. It also may contain small amounts of sulfur, nitrogen, and other impurities. The composition can vary depending on the source of the oil.

The two products of complete combustion of a fuel like petrol are carbon dioxide (CO2) and water (H2O).

Crude oil comes from the reservoir as live crude, containing methane and other lower carbon compounds that are liberated as the pressure is reduced (in the reservoir, in the well, in the separator or storage battery) and the crude is allowed to cool. Dead crude is degassed crude meaning no more gas is likely to be liberated. The volumetric measurement of crude is normally done at "standard conditions" of atmospheric pressure and 60 degrees F, although standards vary.

Crude oil is a liquid formed by dead plankton and by immense pressure and heat and is made up of hydrocarbons while coal is a solid formed of dead plant matter which is then squashed up into what's called peat and then layers of rock squash the water out of the peat and it then makes coal. They both take thousands of years to form and are therefore a fossil fuel. :) I just learnt this in year ten chem hope it explains it enough :)

Crude oil is formed from the remains of ancient marine organisms, such as algae and plankton, that were buried in sedimentary rocks millions of years ago. Over time, heat and pressure transformed these organic materials into the hydrocarbons that make up crude oil.

crude oil is just that, crude. It is not required to know the exact composition of crude oil. Each manufacturer of crude oil will have a different combination to each other.

-Yeah, but each must contain some identical chemicals, otherwise it wouldn't be oil.

-Also it wouldn't be considered a mineral if it didn't have some type of combination of elements.

The energy obtained from petroleum is in the form of chemical potential energy, which is stored in the hydrocarbon molecules. When petroleum is burned, this stored energy is released as heat and light energy, which can be used for various applications such as generating electricity or powering vehicles.

Texas Tea

45 gallons of crude oil weighs about 315 pounds.

No, petroleum jelly does not contain latex. Petroleum jelly is made from petroleum, while latex is derived from the milky sap of rubber trees. They are two different substances with different chemical compositions.

Most of the time. Here is one definition from "thefreedictionary": A thick, flammable, yellow-to-black mixture of gaseous, liquid, and solid hydrocarbons that occurs naturally beneath the earth's surface, can be separated into fractions including natural gas, gasoline, naphtha, kerosene, fuel and lubricating oils, paraffin wax, and asphalt and is used as raw material for a wide variety of derivative products. ====== Here's another from Merriam-Webster: an oily flammable bituminous liquid that may vary from almost colorless to black, occurs in many places in the upper strata of the earth, is a complex mixture of hydrocarbons with small amounts of other substances, and is prepared for use as gasoline, naphtha, or other products by various refining processes. ====== The first definition is a bit confusing as it sounds like petroleum is a mixture of solids, liquids and gases. In the reservoir, the oil phase can contained dissolved gas. When the oil is produced, the gas will come out of solution. Because of the liberation of gas, there is some shrinkage of oil. If there is any confusion, then it is better to state "hydrocarbon liquids", "crude oil" or "petroleum liquids."

Hydrocarbons.

Difference in the boiling points among different byproducts of crude oil is used to separate out each component from a mixture. Fractional distillation is used to carry out this process. This method can also be used to purify water and acetone from a mixture.

Petroleum is believed to have, formed over a period of millions of years, from organisms that lived in the sea at that time. When these organisms died, their bodies settled on the seabed, and got covered with sand and clay. Over millions of years, heat and pressure changed the dead organisms into petroleum.

The transmissibility formula in petroleum engineering is given by T = kh/u, where T is the transmissibility, k is the permeability, h is the thickness of the reservoir, and u is the fluid viscosity. It represents the ease with which fluids can flow through the reservoir rock.

Natural gas is considered the cleanest burning petroleum product. When it is burned, it produces lower levels of greenhouse gas emissions and pollutants compared to other petroleum products like diesel or gasoline.

It depends on your specific needs. Petroleum can be used for both fuels and petrochemicals. Fuels are typically made from crude oil through processes like refining, while petrochemicals are derived from petroleum byproducts and are used in the production of a variety of products like plastics, rubber, and chemicals. The choice between fuels and petrochemicals will depend on factors such as market demand, economic considerations, and environmental impacts.

The energy in petroleum and coal is stored as chemical energy. This energy is released when these substances are burned, producing heat and other forms of energy.

Some toothpastes contain ingredients derived from petroleum, such as surfactants and humectants. However, not all toothpastes are made entirely of petroleum-based ingredients. It's best to check the specific toothpaste product for a comprehensive list of ingredients.

Fossil fuels. They are formed from the decomposition of organic matter over millions of years and are non-renewable sources of energy.

The transportation sector consumes the majority of the nation's petroleum, accounting for around 60% of total petroleum consumption in the United States. This includes gasoline used by cars, diesel for trucks, and jet fuel for airplanes.

Yellow oil is a term used to describe oils that have a yellow tint or color. It can refer to various types of oils, such as sunflower oil, safflower oil, or even essential oils like lemon or turmeric oil. Yellow oil usually gets its color from the presence of carotenoids, chlorophyll, or other natural compounds in the oil.

Geophysical well logging techniques involve using tools to measure properties like electrical resistivity, sonic velocity, and gamma-ray emissions in a borehole. Each tool provides information about the subsurface geology. Diagrams illustrating these tools show how they are lowered into the well and how data is collected at various depths.

Good question! Simple answer is: Yes for some detergents. Detergents are formulations of many different chemicals, but they all require a "surface active" agent or surfactant to clean off oily grime that would not easily come off with just water alone. Both petrochemical (from petroleum) or oleochemical (from animal and plants) surfactants are used in detergents. While oleochemicals can come from both animal and plants, surfactant chemicals are generally plant based. One question raises another. Is it better to use only oleochemical based detergents based on plants, a renewable resource? The answer is not at all clear, either from an environmental or energy conservation persective, as discussed in the attached link. One aspected pointed out in the second link- cold water detergent requires use of petrochemical surfactant, so there's a energy savings in terms of heating water. I've included two links. Note that one link is prepared from Proctor and Gamble, a maker of many detergents, however I felt in this case, the discussion was presented in an unbiased manner. They conclude that a blend of both petrochemical and oleochemical surfactants can produce the best product for the consumer. There are many related links on oleochemicals, petrochemicals and surfactant chemicals.

Petroleum products are typically measured in volume using units such as barrels (bbl) or gallons. For practical purposes, other units like liters or tons may also be used depending on the region and specific product. Measurements are important for trading, transportation, and storage of petroleum products.
