Deparaffiniseres

Deparaffiniseres refers to the process of removing paraffin wax from a sample. This is a common procedure in various scientific and industrial fields, particularly in histology and oil refining. In histology, paraffin wax is used to embed tissue samples, making them firm enough to be thinly sliced for microscopic examination. The deparaffinisation step is crucial to remove this wax so that the tissue can be properly stained and viewed. Solvents such as xylene or limonene are typically used to dissolve the paraffin.

In the context of petroleum refining, deparaffinisation is the process of removing wax from crude oil or its fractions. Paraffin waxes can crystallize out of oil at lower temperatures, causing problems such as increased viscosity, solidification, and blockage of pipelines. Various methods are employed for deparaffinisation in the oil industry, including solvent dewaxing, catalytic dewaxing, and mild hydrocracking. These processes aim to improve the low-temperature flow properties of fuels and lubricants. The specific technique chosen depends on the type of oil product and the desired level of wax removal.
