Biogas Treatment and Washing Plant for Livestock Waste Valorization

Project Description

Integral design of a biogas purification plant derived from slurry fermentation. The system consists of a set of large-scale tanks manufactured in Glass-Fiber Reinforced Polyester (GRP), interconnected by a complex network of piping for the recycling and regeneration of filtering material across different washing stages.

Industrial Sector

Renewable Energy / Waste Treatment (Biogas and Environment).

Technological Challenge

The primary challenge was to ensure a completely homogeneous flow distribution of gas inside the reactors to maximize filter bed efficiency. At a constructive level, it was necessary to design complex internal compartments and integrated access structures within the GRP tanks—a material requiring highly precise stiffness calculations and mechanical joints to prevent deformation under load.

Development

Parametric 3D modeling was carried out with SolidWorks, integrating all internal components and the piping architecture. Parallelly, a Computational Fluid Dynamics (CFD) simulation was developed to analyze gas behavior upon entering the tanks, allowing for the optimization of diffuser geometry to ensure gas hits the bed uniformly without preferential channeling. Finally, detailed construction plans were generated in AutoCAD, strictly adapted to the client’s manufacturing specificities and sector quality standards.

Result

Generation of a set of plans to build a high-efficiency washing plant that guarantees biogas purity for subsequent energy use. Thanks to the prior simulation, the risk of dead zones inside the reactors was eliminated, extending the filter material’s lifespan and reducing maintenance costs. The technical documentation facilitated deviation-free manufacturing and assembly, meeting the most demanding technical requirements of the installation.
