INTRODUCTION
Wax is an organic, plastic-like substance that is solid at ambient
temperature and becomes liquid when melted.
In general terms, waxes are naturally or synthetically
derived.
Crude oil is transported to refineries where it is refined into
finished products by complex processes.
One of the many products derived from refining is lube/base
oils.
The waxes are produced in the lube/oil refining process.
Petroleum waxes as a mixture of hydrocarbons are classified into
three general categories. They include microcrystalline,
macrocrystalline, and semi-microcrystalline paraffin wax. our
Paraffin Waxes are macrocrystalline and provide a wide variety of
physical characteristics such as oil content and melting point,…
can be used in a wide range of industries.
PRODUCTION OF PETROLEUM WAXES
Base oils are produced in a series of steps that are designed to
enhance certain desirable properties such as viscosity index,
low-temperature properties...
In the base oil production process, the solvent extracted lube
fraction is dewaxed by chilling to a low temperature which removes
much of the wax.
This improves the low-temperature fluidity of the product and
produces dewaxed lube fractions and slack wax. Chart 1 illustrates
the refining process in our company. Through deoiling/sweating of
slack wax, paraffin waxes are obtained.
