What is naphthenic base oil?

Naphthenic base oil are group V base oil and are derived from sweet crude distillates by hydro-treating process at a pressure above 2500 psi. Naphthenic base oil possess low pour point, high solvency, low wax, and low aromatic content.

What is heavy naphthenic?

Hydrotreated heavy naphthenic distillates (petroleum) Definition: A complex combination of hydrocarbons obtained by treating a petroleum fraction with hydrogen in the presence of a catalyst.

What is the difference between paraffinic and naphthenic oil?

The differences between these different types of oils are not clear-cut, but mainly depend on the predominant hydrocarbon types in the oil. Paraffinic oil, for example, contains primarily higher alkanes, whereas naphthenic oils have a high share of cyclic alkanes in the mixture.

What are the properties of naphthenic oil?

Its known characteristics are as follows: high solvency, good low temperature property, good compatibility with some resin and polymers, and good ability to plasticize rubber and miscibility with rubber. Due to these advantages, naphthenic oil has been studied a lot in the rubber industry in recent years.

What is the use of naphthenic oils?

MaxNap naphthenic base oils offer high solvency, low pour points, and good color characteristics that are perfect for a wide range of applications including metalworking fluids, grease, adhesives, printing inks, and transformer oils.

What is naphthenic acid used for?

The major uses of naphthenic acids are as oil-soluble metal soaps for driers and other catalysts, wood preservatives, tire cord adhesion promoters, and in amine derivatives for corrosion inhibitors.

What is another name for naphthenic crude?

Naphthenic compounds are sometimes called naphthenes, cycloparaffins, or hydrogenated benzenes. Naphtha is a refined petroleum fraction that contains a high percentage of these types of hydrocarbons.

Is naphthenic acid toxic?

Abstract. Naphthenic acids (NAs) are constituents of oil sands process-affected water (OSPW). These compounds can be both toxic and persistent and thus are a primary concern for the ultimate remediation of tailings ponds in northern Alberta’s oil sands regions.

Where is naphthenic acid found?

Abstract. Naphthenic acids (NAs) are widely present in crude oil and oil sands process-affected water (OSPW). NAs in crude oil lead to corrosion problems, promote emulsion formation, decrease oil quality, and deactivate catalysts, making it critical to isolate NAs.

What is naphthenic hydrocarbon?

1. n. [Drilling Fluids] A type of organic compound of carbon and hydrogen that contains one or more saturated cyclic (ring) structures, or contains such structures as a major portion of the molecule. The general formula is CnH2n.

Is glycerin a mineral oil?

Glycerol, also known as glycerin or glycerine, is actually an alcohol. Its molecules only contain 3 carbons, and it has a density of about 1.3 g/mL. Unlike mineral oil, it is soluble in water. In fact, it is hygroscopic, meaning glycerol will actually absorb water vapor from the air.

What are other names for mineral oil?

They can be found under names such as MINERAL OIL, PARAFFINUM LIQUIDUM, PETROLATUM, CERA MICROCRISTALLINA, MICROCRYSTALLINE WAX, OZOKERITE, CERESINE ISOPARAFFIN, PARAFFIN and SYNTHETIC WAX.

Is naphthenic oil toxic?

Abstract. Naphthenic acids (NAs) are considered to be a major toxic component of oil sands process-affected waters (OSPW) and are also widely used for industrial processes.

Can the toxicity of naphthenic acids in oil sands process affected water be mitigated by a green photocatalytic method?

Chronic toxicity of NAFC can be mitigated by high-intensity photocatalytic treatment.

Are naphthenic acids organic?

The organic fraction (often isolated as acid extractable organics; AEOs) contains a group of toxic compounds referred to as naphthenic acids (NAs).

What is heavy mineral oil used for?

Heavy Mineral Oil is used for relief of occasional constipation, particularly in the presence of hemorrhoids and painful conditions of the anus or rectum. Can also be used externally as a skin emollient.

Is glycerin the same as mineral oil?

What is the difference between light and heavy mineral oil?

The difference between light and heavy mineral oil (the low- and high-viscosity variants, respectively) is that the light variant contains more cyclic (saturated) molecules that prevent the consistent build-up of the palisade. Light mineral oil is therefore less occlusive than heavy mineral oil.

What are naphthenic oils?

Naphthenic oils have been proven to be suitable in the tyre oils segment because of their low content of polycyclic aromatic hydrocarbons (PAHs), which are hazardous to health and the environment. 3. Lubricating oils. Base oils are needed to manufacture products such as greases and industrial lubricants.

What is the difference between naphthenic oil and paraffinic oil?

The differences between these different types of oils are not clear-cut, but mainly depend on the predominant hydrocarbon types in the oil. Paraffinic oil, for example, contains primarily higher alkanes, whereas naphthenic oils have a high share of cyclic alkanes in the mixture.

Are distillates (petroleum) and hydrotreated heavy naphthenic hazardous to the environment?

Following UN GHS criteria, Distillates (petroleum), hydrotreated heavy naphthenic are not classified for environmental hazards. Distillates (petroleum), hydrotreated heavy naphthenic are liquid under normal conditions and if entering soil they will quickly adsorb to soil particles, be of low mobility and not contaminate ground water.

What is the difference between naphthenic hydrocarbons and kW high values?

High values of Kw (13-12.5) indicate a predominately paraffinic character of its components; naphthenic hydrocarbons vary between 12-11 and values near 10 indicate aromatic character. 2. Chemical composition
