Engineering and Simulation of Environmental Processes Group

(GESPA)

GESPA’s research is framed within environmental engineering and molecular and process simulation. The group consists of a team of multidisciplinary scientists who combine chemical engineering, biotechnology, and analysis with a theoretical-experimental approach to improve the sustainability of processes. The aim is to respond to the current challenges of society: climate change, water scarcity, and population growth.

 

The group’s main lines of research focus on three main areas:

 

  1. Water treatment and reuse: Development of new, more efficient, and more sustainable disinfection processes, advanced oxidation (AOP), adsorption, membranes, biofilms, removal of recalcitrant organic compounds by fungi and nitrogen removal by partial nitrification, and Anammox processes.
  2. Greenhouse gas impact mitigation: CO2 capture, transport, storage, and/or transformation and reduction of N2O emissions in water treatment and fluorinated gas treatment.
  3. Sustainable energy growth: Energy recovery from biomass, optimization of lignocellulosic biorefinery processes to obtain 2nd and 3rd generation biofuels and phenolic resins from lignin, and the search for more efficient and environmentally sustainable alternative solvents.

These research areas are complemented by two major transversal lines applicable to the three previous areas:

 

Molecular and process modelling: development and application of advanced equations of state (SAFT) for thermophysical characterization of solvents and fluids of interest, molecular dynamics and Monte Carlo simulations, computational fluid dynamics (CFD), process simulations (Aspen Hysysys), and life cycle analysis (LCA).

 

Analytical Techniques: development of methods for the analytical determination of persistent organic pollutants (dioxins, furans, polychlorinated biphenyls, flame retardants, etc.) and their application to the monitoring of degradation processes and the establishment of their levels in environmental and food matrices.

 

In this environment, GESPA carries out its RD and technology transfer activities in the following areas:

  • Molecular and process modelling
  • Development and application of advanced equations of state (SAFT) for thermophysical characterization of solvents and fluids of interest.
  • Molecular dynamics and Monte Carlo simulations, computational fluid dynamics (CFD)
  • Process simulations (Aspen Hysys) and life cycle analysis (LCA)
  • Analytical techniques
  • Analytical determination of persistent organic pollutants (dioxins, furans, polychlorinated biphenyls, flame retardants, etc.)
  • Application to the monitoring of degradation processes and the establishment of levels in environmental and food matrices
  • Gas Chromatograph (HRGC) coupled to High Resolution Mass Spectrometer (HRMS)
  • Gas Chromatographs (HRGC) with flame ionisation detector (FID) and electron capture detector (ECD)
