How is petrol separated from crude oil?

User Avatar

Asked by Wiki User

By fractional distillation.

It distils off as octane.

However, octane is a straight chain alkane. So to make octane combust/burn more efficiently, octane is then 'reformed' into petrol .

Asked by Wiki User

We have oil because millions of years ago lots of animals died and they rotted over thousends of years and turned into oil.

Why petroleum is not a mineral?

User Avatar

Asked by Wiki User

A mineral needs to be inorganic (no carbon in it and petroleum DEFINITELY has carbon) and a mineral also needs to be a solid and have a crystal structure, which only solids have. A2-out of curiosity and to learn more, I looked up "mineral" in Wikipedia. Certainly it should be a solid, crystalline, and have a defined chemical composition. Thus mixtures of minerals as often found are excluded, at least until separated. Interestingly, the Wiki article does mention organic minerals including hydrocarbons! A complication is that the term "mineral oil" is often used to describe liquids obtained from crude oil. These come under a separate Wikipedia heading for Mineral Oils. However it appears to strictly be a misnomer, some other name such as "Natural Non-Vegetable Oils" might be better but the present use of the term Mineral Oil is probably too well established.

User Avatar

Asked by ChrissyNguyen

D ; All of them.

NB When we breath out )Exhale/Respire) we breath outy carbon dioxide.

B ; Volcanoes releaser carbon dioxide, together with other gases e,g, steam, sulphur dioxide, hydrogen sulphide , amongst other gases and liquid rocks.

C ; We burn fossil fuels(petrol/gas/diesel) in cars and power stations. They also release CO2.

How is the chemical energy in fossil fuels changed to electricity energy?

User Avatar

Asked by Wiki User

The fossil fuel is combusted in a boiler.

In doing so the boiler is filled with water; it boils ; and forms steam under pressure.

This pressurised steam is passed from the boiler to a turbine , which the steam makes the turbine rotate.

This turbine rotation is connected to a long shaft made of magnetised iron , which . This magnetised iron is rotated inside a coil of wire.. Remember when rotating a magnet inside a wire coil makes the electrons in the wire coil move, hence electricity.

Where does the word diesel come from?

User Avatar

Asked by Wiki User

'Diesel' comes the German engineer, Rudoplf Diesel. Diesel invented an internal combustion engine that would auto ignite, when the fuel vapours were compressed to a high degree. This increased the temperature of the vapour to the point were it would auto ignite.

The fuel that he used was slightly different from petrol, which needed an electrical spark to ignite. This slightly different fuel is now known as 'Diesel'.

An oil well is usually drilled into?

User Avatar

Asked by Wiki User

An oil well is usually drilled into underground rock formations, specifically into geological structures that contain oil reserves. These formations are typically sedimentary rocks, such as sandstone or limestone, which have trapped and preserved oil over millions of years. The drilling process allows for the extraction of crude oil from these reservoirs.

What are the elements in burning fossil fuels?

User Avatar

Asked by Wiki User

Burning fossil fuels, such as coal, oil, and natural gas, primarily involves the combustion of hydrocarbons. The main elements present in fossil fuels are carbon (C) and hydrogen (H). When these hydrocarbons burn, they react with oxygen (O2) from the air to produce carbon dioxide (CO2) and water (H2O), along with other byproducts depending on the specific fuel composition.

Why are fossil fuels getting depleted?

User Avatar

Asked by Wiki User

Fossil fuels are getting depleted because they are formed from the remains of ancient plants and animals that lived millions of years ago. The extraction and consumption of these fuels at a rapid rate far exceeds the time it takes for new deposits to form. Additionally, the burning of fossil fuels releases carbon dioxide into the atmosphere, contributing to climate change, which has pushed for a shift towards renewable energy sources.

How did plants and animals get their energy before they became fossil fuels?

User Avatar

Asked by Wiki User

Plants derive energy through photosynthesis, where they convert sunlight into chemical energy. Animals obtain their energy by consuming plants or other animals. In this way, energy flows through the food chain, with each organism relying on the energy stored in the organisms they consume. Before the formation of fossil fuels, the primary sources of energy were natural phenomena such as sunlight, wind, and organic matter from living organisms.

Why does heat energy leave the house?

User Avatar

Asked by Wiki User

Heat energy leaves the house due to convection, conduction, and radiation. Convection occurs when warm air rises and is replaced by cooler air, carrying heat energy out. Conduction transfers heat through direct contact with colder objects like windows and walls. Lastly, radiation allows heat energy to escape as infrared radiation through windows and gaps in insulation.

What is a drawback for using fossil fuels?

User Avatar

Asked by Wiki User

Fossil fuels, such as coal, oil, and natural gas, have long been the primary source of energy for industrial, transportation, and residential purposes. However, they come with several significant drawbacks, including:

Environmental Impact: Fossil fuel combustion releases greenhouse gases like carbon dioxide (CO2) into the atmosphere, contributing to global climate change and causing air pollution. This results in various environmental problems, including rising temperatures, sea-level rise, and extreme weather events.

Depletion of Resources: Fossil fuels are finite resources. As they are extracted and consumed, reserves deplete, leading to concerns about future energy security and rising costs of extraction as resources become scarcer.

Air and Water Pollution: Burning fossil fuels produces pollutants like sulfur dioxide (SO2), nitrogen oxides (NOx), particulate matter, and volatile organic compounds. These pollutants can harm human health, lead to acid rain, and contaminate water sources.

Habitat Disruption: Extracting fossil fuels can disrupt ecosystems and wildlife habitats. For example, mining and drilling can destroy forests and wetlands, and the construction of infrastructure, such as pipelines and roads, can fragment habitats.

Spills and Accidents: Transportation and processing of fossil fuels can lead to accidents, such as oil spills from tankers or pipeline leaks, which can have devastating effects on ecosystems and local communities.

Geopolitical Tensions: Many nations depend on fossil fuels, and this dependence can lead to geopolitical tensions, conflicts, and power imbalances in regions with abundant reserves.

Price Volatility: Fossil fuel prices are subject to significant fluctuations due to factors such as supply disruptions, geopolitical events, and changes in demand. This volatility can impact energy security and economic stability.

Health Impacts: Air pollution from fossil fuel combustion is linked to respiratory and cardiovascular diseases. Long-term exposure to polluted air can lead to serious health problems.

Energy Inefficiency: The process of extracting, refining, and transporting fossil fuels is energy-intensive. This results in a significant energy loss before the final product reaches end-users.

Limited Energy Diversity: Overreliance on fossil fuels can make energy systems vulnerable to supply disruptions and price spikes. Diversifying energy sources can enhance energy security.

Given these drawbacks, there is a growing global shift towards cleaner and more sustainable energy sources, such as renewable energy (solar, wind, hydroelectric), to reduce the negative impacts associated with fossil fuels and combat climate change.

Why is petroleum called crude oil?

User Avatar

Asked by Wiki User

Commonly, Petroleum is regarded as a very close synonym of Crude Oil. However, according to Britannica Encyclopedia, petroleum as a technical term encompasses: the liquid (crude oil), gaseous (natural gas), and viscous or solid forms (bitumen and asphalt).

Why is crude oil called a fossil fuel?

User Avatar

Asked by Wiki User

Oil is called a fossil fuel because it is made from animals which died and were cemented in mud and heat many years ago. They turned into oil and a type of gas called methane thousands of years later. They are not actually fossils but the equivalent of them because they have been preserved by the mud and eventually turned into oil, a type of fuel.

Are Polyethylene and polypropylene made from crude oil?

User Avatar

Asked by Wiki User

NO. See Link. YES! From http://www.sustainablebusiness.com/index.cfm/go/news.feature/id/1363 Traditional foam "to-go" containers are made of polystyrene, while the clear plastic containers and bottles we see everywhere are made of polyethylene terephthalate (PET), polystyrene or polypropylene -- all petroleum-based plastic polymers. The ubiquitous paper coffee cup, and the paper take-out containers we see everywhere, also use a petroleum-based plastic coating to make them waterproof.

According to Green Seal, in 1997, 120 million pounds of foam polystyrene hinged containers were used in the U.S. food packaging industry and each American throws away an average of 100 polystyrene cups each year. Green Mountain Coffee Roasters recently estimated that last year Americans used 14.4 billion hot paper cups (placed end-to-end, this many cups would circle the world 55 times).

Not only do these plastic cups and take-out containers create garbage that ends up in the landfill for centuries to come (a polystyrene cup has an expected lifetime of over 500 years), they are made from non-renewable petrochemicals, and styrene, a key ingredient of polystyrene, is a suspected carcinogen and known hazardous substance.
