Wax deposition or paraffin deposition refers to the accumulation of paraffin wax on the surface of a substance, typically a liquid or gas. This can occur in a variety of contexts, including the production and transport of oil and natural gas, the refining of petroleum products, and the storage and transport of chemicals.
Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F), [ 2 ] and its boiling point is above 370 °C (698 °F). [ 2 ]
Kerosene, or paraffin, is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from κηρฯς ( kฤrós ) meaning " wax ", and was registered as a trademark by Nova Scotia geologist and inventor Abraham Gesner in 1854 before evolving into a generic ...
Paraffin wax, used in the candle industry, among others. May be shipped in bulk to a site to prepare as packaged blocks. May be shipped in bulk to a site to prepare as packaged blocks. Used for wax emulsions, candles, matches, rust protection, vapor barriers, construction board, and packaging of frozen foods .
Paraffin waxes are mixtures of saturated n- and iso- alkanes, naphthenes, and alkyl- and naphthene-substituted aromatic compounds. A typical alkane paraffin wax chemical composition comprises hydrocarbons with the general formula C n H 2n+2, such as hentriacontane, C 31 H 64. The degree of branching has an important influence on the properties.
Chlorinated paraffins (CPs) are complex mixtures of polychlorinated n-alkanes (paraffin wax). The chlorination degree of CPs can vary between 30 and 70 wt% . CPs are subdivided according to their carbon chain length into short-chain CPs (SCCPs, C 10–13 ), medium-chain CPs (MCCPs, C 14–17 ) and long-chain CPs (LCCPs, C >17 ).
