White Spirit Production

White spirit production turns petroleum naphtha or kerosene fractions into a clear, low-odour solvent used across paints, cleaning, and degreasing. The essence of the process is taking a feedstock rich in hydrocarbons and refining it to a narrow boiling range with the impurities and colour removed, so it performs reliably and safely in industrial and household applications.

Purifying the Feedstock

The chosen fraction first passes through purification, often hydrotreating, which reacts the feedstock with hydrogen over a catalyst to strip out sulfur and other impurities that would hurt quality or odour. This step is what gives white spirit its clean profile and low reactivity, making it suitable for formulations where residual contamination would be unacceptable.

Fractionating to a Tight Cut

Purified feedstock is then fractionally distilled, separating components by boiling point so the producer can collect the specific range that defines white spirit. Precise control of temperature and pressure isolates the desired cut from lighter and heavier fractions, and the collected material may be blended or dosed with additives to tune drying time and odour to a given market.

Alternative Separation Routes

Beyond straight fractionation, solvent extraction uses the differing solubility of components in a chosen solvent to isolate the target product, while hydrogenation saturates unsaturated bonds to lift stability and shelf life. Each route has a role depending on feedstock and purity targets, and the right white spirit production path balances yield, quality, and cost.
