Characterization of Paraffinic Composition in Crude Oils
crude oils besides depending on pressure temperature and composition of crude oils The paraffin in crude oil is of those normal hydrocarbons with high carbon number Normal hydrocarbons that composed of more than 16 carbons are called “wax” (Biao and Lijian 1995) |
What does paraffin mean in chemistry?
In chemistry, paraffin is used synonymously with alkane, indicating hydrocarbons with the general formula C n H 2n+2. The name is derived from Latin parum ("very little") + affinis, meaning "lacking affinity " or "lacking reactivity ", referring to paraffin's unreactive nature.
Are alkane-isoparaffinic products synthesized?
Cycloalkanes and aromatics are absent. They differ from petroleum distillates in the composition of the branched alkanes (pattern is not characteristic for crude oil), and in the absence of isoprenoïds (present in crude oil). These differences indicate that the Normal Alkane-Isoparaffinic products are produced synthetically.
What is the feedstock for paraffin?
The feedstock for paraffin is slack wax, which is a mixture of oil and wax, a byproduct from the refining of lubricating oil. The first step in making paraffin wax is to remove the oil (de-oiling or de-waxing) from the slack wax. The oil is separated by crystallization.
Is paraffin waxy in crude oil transport influenced by hydrocarbon structure?
Characterization of Paraffinic Composition in Crude Oils Lumpur, Malaysia. of paraffin waxy in crude oils transportation. This is highly influenced by the structure of hydrocarbons in the produced composition from the well. In this paper, investigations on the behaviour of waxy crudes, especially in Malaysian oil basins, were carried out.

What is paraffin in crude oil?
- The paraffin in crude oil is of those normal hydrocarbons with high carbon number.
. Normal hydrocarbons that composed of more than 16 carbons are called “wax”, (Biao and Lijian, 1995).
. The wax in crude oils is a mixture of normal hydrocarbons with different carbon number distributions.
How are distillates (petroleum) hydrotreated heavy paraffinic used?
- How are Distillates (petroleum), hydrotreated heavy paraffinic used? They are used as blending component in a variety of industrial and automotive lubricants and functional fluids.
. Health, Safety and Environmental considerations
Are hydrotreated heavy paraffinic base oils mutagenic?
- It can be concluded from extensive studies on the mutagenic potential of hydrotreated heavy paraffinic base oils that they are not considered to be germ cell mutagens.
. They are also not expected to be carcinogenic following the investigation of long-term dermal exposure of laboratory animals.
Is paraffin waxy gelation a significant risk to flow assurance?
- ABSTRACT One of the significant risks in flow assurance management would be the deposition and gelation of paraffin waxy in crude oils transportation.
. This is highly influenced by the structure of hydrocarbons in the produced composition from the well.
