Paraffin Wax Production
how paraffin wax is produced? 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 we refined into finished products by complex processes.
One of the many products derived from refining is lube/base oils.
Furthermore we produced the waxes in the lube / oil refining process.
Petroleum waxes as a mixture of hydrocarbons are classified in three general categories . They include microcrystalline, macrocystalline and semi-microcrystalline paraffin wax. Paraffinco Paraffin Waxes are macrocrystalline and provide a wide variety of physical characteristics such as oil content and melting point,… we can use in a wide range of industries.
PRODUCTION OF PETROLEUM WAXES
We produce Base oils in a series of steps which we design to enhance certain desirable properties such as viscosity index, low temperature properties…
In base oil production process, we dewax the solvent extracted lube fraction by chilling to a low temperature which removes much of the wax.
Also this improves the low temperature fluidity of the product, and produces dewaxed lube fractions and slack wax. Chart 1 illustrates refining process in PUBLTD oil Co.Through deoiling / sweating of slack wax, paraffin waxes we obtained that.
paraffin wax, colourless or white, somewhat translucent, hard wax consisting of a mixture of solid straight-chain hydrocarbons ranging in melting point from about 48° to 66° C (120° to 150° F). We obtained Paraffin wax from petroleum by dewaxing light lubricating oil stocks. We use that in candles, wax paper, polishes, cosmetics, and electrical insulators. It assists in extracting perfumes from flowers, forms a base for medical ointments, and supplies a waterproof coating for wood. In wood and paper matches, it helps to ignite the matchstick by supplying an easily vaporized hydrocarbon fuel.
How paraffin wax is produced? Paraffin wax was first produced commercially in 1867, less than 10 years after the first petroleum well that we drilled. Paraffin wax precipitates readily from petroleum on chilling. Technical progress has served only to make the separations and filtration more efficient and economical. Purification methods consist of chemical treatment, decolorization by adsorbents, and fractionation of the separated waxes into grades by distillation, recrystallization, or both. Crude oils differ widely in wax content.

In addition we introduced Synthetic paraffin wax commercially after World War II as one of the products obtained in the Fischer–Tropsch reaction, which converts coal gas to hydrocarbons. Snow-white and harder than petroleum paraffin wax, the synthetic product has a unique character and high purity that make it a suitable replacement for certain vegetable waxes and as a modifier for petroleum waxes and for some plastics, such as polyethylene. Synthetic paraffin waxes may be oxidized to yield pale-yellow, hard waxes of high molecular weight that we can saponified with aqueous solutions of organic or inorganic alkalies, such as borax, sodium hydroxide, triethanolamine, and morpholine. These wax dispersions serve as heavy-duty floor wax, as waterproofing for textiles and paper, as tanning agents for leather, as metal-drawing lubricants, as rust preventives, and for masonry and concrete treatment.
