Group of Intensification of Chemical and Environmental Processes (INPROQUIMA)

Department of Chemical Engineering and Materials
Facultad de Ciencias Químicas

INPROQUIMA focuses its activities on sustainable development research. The research lines are related to industrial and environmental processes, to improve the quality of products, the energy balance, the process safety and environmental concerns. The group’s evolution is strongly linked to the demand for knowledge in processes of industrial or environmental interest. Currently, the group collaborates with different companies (EMGRISA, SARGA, DISEPROSA, EthicalChem, etc), public organizations (Gov. Aragon, Gov. Madrid) and research groups, with a wide network of international contacts

INPROQUIMA has published more than 100 articles in the fields of chemical engineering, environmental engineering, biotechnology, aquatic resources and environmental sciences and has participated in 10 competitive national projects one European project and 8 projects with private companies, some of them of great importance in the chemical and environmental sector.

The research group has a lab for the chemical treatment of soil and groundwater remediation at batch and column scale and the software, commercial and developed by INPROQUIMA, for modelling and optimizing chemical and environmental processes.

The current research lines are focused on Advanced Chemical Processes applied to the remediation of soil and water polluted with organic compounds. Catalyst and/or reagents are used in homogeneous or heterogeneous media.
The candidate will work on the remediation of sites highly polluted with wastes coming from the manufacture of obsolete pesticides, spills/leaks of chlorinated solvents or hydrocarbons. Different treatments can be applied depending on the type and location of the contamination:
– in situ (injecting the reagents in the subsurface)
– on-site (treatment of the extracted groundwater or excavated soils)
The treatments currently studied are:
ISCO (In situ chemical oxidation): injection of the oxidants/activators in the subsurface. The oxidants used are the Fenton´s reagent and Persulfate activated by alkali/ metals/ temperature, etc.
S-ISCO, ISCO enhanced by the addition of surfactants. The surfactants increase the solubility of the organic compounds in the aqueous phase, enhancing their oxidation rate and removal.
SEAR (Surfactant Enhancement Aquifer Remediation). Injection of biodegradable surfactants to extract residual DNAPLs and further treatment of the fluids recovered.
Chemical reduction, using zero valent iron (doped or not with metallic catalysts). It can be applied in situ by injecting micro or nanoparticles or building PRBs, or on site, to polluted groundwater or soils.
Advanced oxidation treatments (on site) applied to polluted water (electrooxidation, Fenton, electro-Fenton, catalytic wet peroxide oxidation, photocatalysis, etc.) or to excavated soils and sediments (Fenton Like, Persulfate, etc.).
Adsorption of pollutants onto AC (with or without previous stripping of pollutants to the gas phase) and regeneration of spent adsorbents.
