Vapour Recovery Units & hydrocarbon Volatile Organic Compounds (VOCs) treatment

CARBOVAC solutions are in line with the various regulations implemented as part of the “fight against Volatile Organic Compound (VOC) emissions” resulting from the distribution of petrol from terminals to service stations (trucks, railcars, marine vessels, storage tanks).

CARBOVAC implements “pressure swing” Vapour Recovery Units (VRUs) based on the most recognized and used process to treat hydrocarbon vapours and overcome losses of valuable product:

  • Adsorption on activated carbon
  • Desorption by vacuum
  • Absorption and recovery of products in liquid phase product


CARBOVAC is the reference company in the use of state-of-the-art dry screw vacuum pumps, specifically adapted to the “pressure swing” VRU process. This choice if vacuum technology ensures robustness of equipment, maximized lifetime of the solution, simplicity of use, optimization of power consumption and minimization of maintenance costs.
