The emission of light solid aromatic particles from any tobacco industry affects the surrounding inhabitants, commonly causing allergies and eye irritation and, of course, uncomfortable odours, therefore, these emissions to the air must be regulated. An increasing in production must be considered in the sizing of mechanisms used to achieve the precipitation and final filtration, before discharging to the atmosphere. A numerical tool was applied to study the internal behaviour of low velocity precipitation tunnel and discharge chimney of the refuses treatment system. The characterization of the two-phase flow streamlines allows determining the velocity gradient profiles across the whole tunnel; which is intimately related with the particle concentration, and deposition zones locations. The application of CFD techniques gives the bases to find new design parameters to improve the precipitation tunnel behaviour capability to manage the increment of the mass flow of particles, due to changes in mass cigarette production.
