Aromatic hydrocarbon oils
Polycyclic aromatic hydrocarbons (aka polyaromatic hydrocarbons) and shortened to PAHs are present in low percentage amounts in crude oil, making them degrade multiple polycyclic aromatic hydrocarbons (PAHs) present in crude oil. The PAHs in the crude oil sample obtained from Digboi oil refinery, India were 11 Mar 2020 The pollutants were trihalomethane, volatile organic compounds, pesticides, nitrate, boron and polycyclic aromatic hydrocarbon.

A notable case is polycyclic aromatic hydrocarbons (PAHs), which have multiple carbon rings and can also be quite persistent in the environment.

Polycyclic aromatic hydrocarbons are primarily found in natural sources such as creosote. They can result from the incomplete combustion of organic matter. PAHs can also be produced geologically when organic sediments are chemically transformed into fossil fuels such as oil and coal.
Aromatic hydrocarbons, also known as arenes, are hydrocarbons that have at least one aromatic ring and are found in most Essential Oils. Hydrocarbons can be gases (e.g. methane and propane), liquids (e.g. hexane and benzene), waxes or low melting solids (e.g. paraffin wax and naphthalene) or polymers (e.g. polyethylene, polypropylene and polystyrene). Polycyclic aromatic hydrocarbons (PAHs) are aromatic hydrocarbons that consist of fused aromatic rings and do not contain heteroatoms or carry substituents. Naphthalene is the simplest example of a PAH. PAHs occur in oil, coal, and tar deposits, and are produced Polycyclic Aromatic Hydrocarbons (PAHs) This term is applied to any hydrocarbon that has two or more aromtaic rings. These molecules are highly lipophilic, which means they have a proclivity for oils and fats, and are also highly carcinogenic. Polycyclic aromatic hydrocarbons are primarily found in natural sources such as creosote. They can result from the incomplete combustion of organic matter. PAHs can also be produced geologically when organic sediments are chemically transformed into fossil fuels such as oil and coal. Mineral oil hydrocarbons (MOHs) are mixtures of thousands of different molecules, generally derived from crude oil [1]. MOHs are composed of open-chain, cyclic, and aromatic hydrocarbons (Figure 1). MOHs are grouped into mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH). MOHs are generally derived from crude oil. They mainly consist of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH). MOSH comprise open-chain, often branched hydrocarbons (commonly named paraffins) and cyclic, saturated hydrocarbons (commonly named naphthenes). MOAH include mono- or polycyclic aromatic hydrocarbons.
Aromatic hydrocarbons are also cyclic but are derivatives of benzene. The rings are characterized by alternating double bonds and, in contrast to olefins, are quite stable, though not as stable as paraffins. Crude oils are complex mixtures of these hydrocarbons. Oils containing primarily paraffin hydrocarbons are called paraffin-based or paraffinic.

MOAH include mono- or polycyclic aromatic hydrocarbons. Mineral oil hydrocarbons (MOH) comprise a diverse group of mixtures of hydrocarbons containing thousands of chemical compounds of different structures and size, derived mainly from crude oil but also produced synthetically from coal, natural gas and biomass. Aromatic hydrocarbons are also cyclic but are derivatives of benzene. The rings are characterized by alternating double bonds and, in contrast to olefins, are quite stable, though not as stable as paraffins. Crude oils are complex mixtures of these hydrocarbons. Oils containing primarily paraffin hydrocarbons are called paraffin-based or paraffinic.
