Hydroprocessing Applications


Fuel and solvent manufacturers can now meet current and future olefin and aromatic strict saturation standards with a high availability process at low cost. Neste's Engineering Solutions' NEXSATTM is the optimum process for hydroprocessing of low-sulphur feedstock in mild operating conditions, followed by product property fine-tuning in a stabilization or fractionation section for the ultimate quality gain.Typical products are low aromatic fuels, aromatic free solvents and highly saturated fine hydrocarbon chemicals.

Our flexible NEXSATTM process can be used for saturation of wide range of olefinic feedstocks or de-aromatization of middle distillates and naphtha, in a design optimized for single or multiple feedstocks. Capital outlay is kept to a minimum, commonly with no need of a dedicated fired heater nor recycle compressor, yet retaining excellent operational availability and low maintenance requirements. Add to that the low cost of catalyst, excellent reactor performance and its high-quality output, and you are sure to consider it a wise investment.


Reliable processing with high availability is of greatest importance for producers of petrochemicals. Light cracked naphtha always contains diolefins that form gums and cause equipment fouling and product degradation amongst others in etherification units. Neste's Engineering Solutions' NEXSELECTTM process removes this problem by selective hydrogenation. Mild temperature eliminates the formation of paraffins, improving the overall yield in these downstream units.

The result is a clean and trouble-free flow throughout your process and better quality in your final product. Investment is minimal because NEXSELECTTM operates in liquid phase and doesn’t need hydrogen recycle compressor. It is easily integrated into the NEXTAMETM and NEXETHERSTM units without more degasification equipment. Low cost for high return is always a wise business choice.
