Newton’s briquettes : drying and neutralization of hydrocarbons

Our Oil&Gas Business Unit is specialized in the drying and the neutralization of hydrocarbons, solvents and liquid gas.

Our production plant, located in Cavaillon (South of France), produces briquettes adapted to each customer requirement.

Newton’s dehydrating briquettes for drying and neutralization of hydrocarbons


Produced in France, the briquettes (or « pillows ») Newton’s are used to dry and neutralize hydrocarbons, solvents and liquid gas. Their shape was developed by our R&D department in order to optimize the water absorption (both dissolved and free water) in hydrocarbons while avoiding « preferential channels ».

Those briquettes have a higher contact area between the solid and the liquid parts, compared to pearls for the same volume. With a similar pressure drop, the contact area increases by around 20.

Other shapes and sizes are available (such as small prills or flakes) but these shapes cause a higher pressure drop through the bed. In this case, chimneys or preferential paths will be formed during the drying operation.

The brine formed from the water collected with the consumption of the briquettes in contact with water is then :

  • Restated (wastewater treatment)
  • Reused as a raw material in other units of the refinery

The benefits of Newton’s briquettes 


Our range of briquettes have many advantages :

  • Significant improvement of the drying timing
  • The briquette shape allows avoiding the « chimney effect ».
  • Product « made in France » in our factory in Cavaillon (certified ISO 9001)
  • Our packaging is adapted to each customer

Besides the hygroscopic properties used for the drying, our briquettes have also optimal alkaline characteristics to be able to neutralize the acid components and impurities in the hydrocarbons (HF, HCl, H2S).
