What is the difference between paraffinic and naphthenic?
What is the difference between paraffinic and naphthenic?
The aniline point of paraffinic oil is much higher than a naphthenic meaning the solvency is worse. Paraffinic oil has a high viscosity index which is good for engine oil but bad for transformers. The naphthenic oil will reach a lower viscosity meaning more oil circulation in the transformer and better cooling.
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.
Is mineral oil a naphthenic?
Crude oil is extracted from the bedrock before being processed in several stages, removing natural contaminants and undesirable hydrocarbons. This separation process produces mineral oil, which can in turn be denoted as paraffinic, naphthenic or aromatic.
What is paraffinic crude oil?
Paraffinic crude oils are rich in straight-chain and branched paraffin hydrocarbons, whereas naphthenic crude oils contain mainly naphthenic and aromatic hydrocarbons. The composition and classification of many crude oils are obtained by ring analysis and by determination of the other constituents (Sachanen, 1950).
Why is paraffin bad?
Most candles today are made of paraffin wax which creates highly toxic benzene and toluene when burned (both are known carcinogens). In fact, the toxins released from paraffin candles are the same as those found in diesel fuel fumes and are linked to asthma and lung cancer.
How many types of base oil are there?
There are three types of base oils: mineral, vegetable, and synthetic.
Why is it called mineral oil?
Mineral oil is any of various colorless, odorless, light mixtures of higher alkanes from a mineral source, particularly a distillate of petroleum, as distinct from usually edible vegetable oils. The name ‘mineral oil’ by itself is imprecise, having been used for many specific oils over the past few centuries.
Is paraffinic oil mineral oil?
Liquid paraffin oil is a mineral oil, and is a by-product of petroleum distillation. It is transparent, colorless, odorless and tasteless oil, which is mainly composed of heavier alkanes.
What is the difference between base oil and mineral oil?
Mineral oil, which is derived from crude oil, can be produced to a range of qualities associated with the oil’s refining process. Vegetable base oils, which are derived from plant oils, represent a very small percentage of lubricants and are used primarily for renewable and environmental interests.
What is the problem with crude oil?
Even though new technology has addressed some of these problems to various extents, of most serious impacts of petroleum use is on global climate change. As a fossil fuel, its combustion contributes to polluting emissions, especially of carbon dioxide, one of the most dangerous of the greenhouse gases.
What are the components of naphthenic oil?
Naphthenic acid (NA) is one of the components of heavy crude oil. It is composed of a carboxylic acid functional group attached to a hydrocarbon molecule. Heavy crude oils with high concentration of NA are usually classified as poor quality oil and are sold at cheaper price.
What is naphthenic based crude?
Naphthenic-based crudes contain a large percentage of cycloparaffins in the heavy components. Examples of this type of crude come from the US midcontinent region. Highly aromatic crudes are less common but are still found around the world.
Is Pennzoil paraffin based?
No, there is not paraffin wax in any Pennzoil products. However, every conventional oil (and most synthetics) on the market today, including Pennzoil, use “paraffinic” base stocks. This is not the same as adding paraffin wax to the oil.
What is a naphthenic solvent?
Definition – What does Naphthenic Solvent mean? A naphthenic solvent is a chemical substance that is a mixture between cyclopently groups and cyclohexyl carboxylic acid that dissolves or extracts other substances, without causing chemical changes to itself.
