Purification process of high-purity liquefied gases from Repsol

From petroleum distillation, we obtain gas currents that are subject to several selective purification processes, eliminating odours, impurities, and heavy components.

In the first phase, liquefied gases are mixed in the appropriate proportion.

HYDROGENATION (High temperatures and pressures).

Gases are mixed in a bi-catalytic hydrogenation reactor where they are subject to high pressures and temperatures for purification, eliminating olefins and sulphur.

STRIPPING Separation phase.

During the Stripping phase, light compounds, excess H2, and H2S are separated with the help of N2.

FILTRATION OF HEAVY COMPOUNDS

The remaining gases are subject to a filtration process that extracts heavy compounds and eliminates any residual impurities.

The content of 1,3-butadiene is much lower than the 0.1% required for these products.

FINAL PRODUCT High-purity liquefied gas

Once purified and having the quality required, liquefied gases are stored at room temperature in closed containers and in a liquid phase, thanks to their own vapour pressure, thereby minimising the space they occupy.
