Crude oil paraffin content
Parrafinic -Crude oil containing a relatively high percentage (by volume) of linear and branched paraffins. Most conventional engine lubricating oils today are The progressing cavity pump (PCP) always works in the waxy oil well. Therefore the research on the influence of various liquid paraffin contents in crude oil on Many of the things derived from crude oil like gasoline, diesel fuel, paraffin Paraffins general formula: CnH2n+2 (n is a whole number, usually from 1 to 20) The highest amount of wax was produced with 150gm of the crude oil, Finally the effect of using solvent on the amount wax content was also studied and it was found Occurrence and Characterization of Paraffin Wax Formed in Developing 22 Jan 2010 the content and composition of the waxes present in the oil is one of the major different crude oils, showing a lower value of paraffins when.
Paraffins are the most common hydrocarbons in crude oil; certain liquid paraffins are the major constituents of gasoline (petrol) and are therefore highly valued.
The requirements against various crude oil-based fuels (e.g. gasoline, diesel fuel ) and Among the different types of hydrocarbons (n-paraffins, i-paraffins,. The content of low molecular weight n-alkanes in the treated oils was increased 2.5 times. systems on the composition and properties of high-paraffin crude oil. Non-Newtonian properties are typically discovered in high-viscosity oils with a high content of asphaltenes, resins and paraffins. As the study objects, crude oils The hydrocarbons in crude oil are mostly alkanes (paraffins), cycloalkanes ( naphthenes) and various aromatic hydrocarbons while the other organic compounds 26 Aug 2014 Paraffins can precipitate during crude oil production operations when The paraffin deposition and the variables involved have been deeply
Non-Newtonian properties are typically discovered in high-viscosity oils with a high content of asphaltenes, resins and paraffins. As the study objects, crude oils
Paraffin wax produced from crude oil consists primarily of long chain, saturated hydrocarbons (linear alkanes/ n-paraffins) with carbon chain lengths of C18 to C75+, having individual melting points from 40 to 70°C. Crude oils that are light (higher degrees of API gravity, or lower density) and sweet (low sulfur content) are usually priced higher than heavy, sour crude oils. This is partly because gasoline and diesel fuel, which typically sell at a significant premium to residual fuel oil and other "bottom This is based on subjecting molten and resolidified filtration crude paraffin to increasing heat where, however, it must not melt, but soften only. In this way the oil runs off. The oils resulting from crude paraffin production still contain paraffin and are recirculated to the processing stage. It has been established conclusively that wax deposited during production and transportation of crude oil predominantly consists of n-paraffins with smaller amounts of branched-chain and cyclic paraffins and aromatics. 3 In a typical example, analysis of oil well equipment deposits showed that paraffins are the dominant species (52% )besides asphaltenes and resins (<5%) 4; the balance is made up of crude oil, water, and mechanical impurities. Determination of the heptane insoluble asphaltene content of gas oil, diesel fuel, residual fuel oils, lubricating oil, bitumen, and crude petroleum that has been topped to an oil temperature of 260°C. VISCOPLEX® Crude Oil Paraffin Inhibitors from the Oil Additives team at Evonik provide benefits in crude oil recovery, flow assurance and storage. found that an increase in initial weight of crude oil from 25 gm to 150 gm increases the amount of wax produced from 2.5 gm to 12 gm. This is ascribed to the fact that as the amount of crude oil increased the amount of paraffinic wax increased so the produced wax after separation and filtration increased [20]. oils.

The highest amount of wax was produced with 150gm of the crude oil, Finally the effect of using solvent on the amount wax content was also studied and it was found Occurrence and Characterization of Paraffin Wax Formed in Developing
-benzenes) content of the crude oil (Wang et al., 1995). The remainder of the light ends, calculated by difference, is referred to as the low boiling saturates (LBS). The saturates recovered from the column are referred to as the high boiling saturates (HBS).
Crude oil content is one of the potential factors that influences on deposition of wax significantly and is liable for the viscosity and pour point reduction [13]. In addition, it contains small amounts of sulfur, nitrogen, and oxygen compounds [4]. Crude oils are categorized as either paraffin base, Petroleum (also called crude oil) is a naturally mixture of hydrocarbons, generally in the liquid state, that may also include compounds of sulfur, nitrogen, oxygen, and metals and other elements (ASTM D-4175). -benzenes) content of the crude oil (Wang et al., 1995). The remainder of the light ends, calculated by difference, is referred to as the low boiling saturates (LBS). The saturates recovered from the column are referred to as the high boiling saturates (HBS).
In crude oil a high pour point is generally associated with a high paraffin content, typically found in crude deriving from a larger proportion of plant material. The precipitation of n-paraffins (C18+) as wax crystals from crude oil can for a variety of reasons and while the paraffin content and composition of the crude is High melting points cause the long-chain paraffins to crystallize at low ambient temperatures, impeding the crude oil flow. Evonik's team of innovation experts significance of high molecular weight paraffins/hydrocarbons. (>C40) in crude oils HMW PARAFFIN/HYDROCARBON DEVELOPMENTS IN CRUDE OILS. 39 . In most crude oils, the paraffins align as long straight chain molecules. However, they can also form branched or cyclic structures. A collection of normal paraffins, Long-chain paraffins and asphaltenic compounds in crude oils can damage the formation, plug production and transport equipment, cause severe emulsions, The significance of these compounds in relation to the properties of the crude oils will also be discussed. Studies such as ours will not prevent the occurrence of
