What are middle distillates?

Glossary Terms » Middle Distillates. A general classification of refined petroleum products that includes distillate fuel oil and kerosene, over-the-road diesel, and home heating oil.

What is the range of carbon for petrol oil?

The hydrocarbons of gasoline contain typically 4-12 carbon atoms with boiling range between 30 and 210 °C, whereas diesel fuel contains hydrocarbons with approximately 12–20 carbon atoms and the boiling range is between 170 and 360 °C.

How many carbons are in naphtha?

Light naphtha is the fraction boiling between 30 °C and 90 °C and consists of molecules with 5–6 carbon atoms. Heavy naphtha boils between 90 °C and 200 °C and consists of molecules with 6–12 carbon atoms.

What are TPH levels?

Total petroleum hydrocarbons (TPH) is typically defined as carbon chains in the range of C6 through C35. Products containing TPH include a wide variety of mixtures that may contain hundreds to thousands of hydrocarbon compounds including aliphatic (straight carbon chain) and aromatic (benzene ring) compounds.

What products are middle distillates?

Middle distillates, which are hence also known as gasoil, primarily include extra light heating oil (heating oil EL), and diesel fuel, as well as marine diesel oil (MDO) as an intermediate stage between middle distillates and heavy fuel oil, and jet fuel (also called Jet A-1 or kerosene).

What is middle distillates trader?

What are Middle Distillates? Middle distillates is the term used to describe a range of refined products, which result from the separation of crude oil through fractional distillation, between lighter products (LPG and gasoline) and heavier products (fuel oil).

How much carbon is there in a barrel of oil?

The average heat content of crude oil is 5.80 mmbtu per barrel (EPA 2021). The average carbon coefficient of crude oil is 20.31 kg carbon per mmbtu (EPA 2021).

How many carbon atoms are in lubricating oil?

The chemical composition of lubricating oils derived from crude oil is particularly complex. Normally lubricating oils contain a high proportion of naphthenic or paraffinic compounds. The hydrocarbons comprising a typical lubricating oil may have from 20 to 70 carbon atoms.

What is full range naphtha?

In petroleum engineering, full range naphtha is defined as the fraction of hydrocarbons in petroleum boiling between 30°C and 200°C. It consists of a complex mixture of hydrocarbon molecules generally having between 5 and 12 carbon atoms. It typically constitutes 15–30% of crude oil, by weight.

How is TPH measured?

]. Traditional wet chemistry methods for determining TPH level in soil samples is based on extracting the contaminant from the soil sample. The TPH level in the extracted solution is then determined by a gravimetric, FTIR, or GC measurement calibrated by an EPA calibration standard.

What is the safe limit of total petroleum hydrocarbon TPH in contaminated soil?

For total petroleum hydrocarbons (TPH) values range from 300 mg/kg to 1000 mg/kg. For soil -> groundwater they depend on protection zones, ranging from 200 mg/kg soil in highly protected areas to 1200 mg/kg for the vadoze zone and deep groundwater levels (>5 m).
