The aim of this work was to study the operation costs of treating a real effluent from an integrated gasification combined cycle (IGCC) power station located in Spain. The study compares different homogeneous photocatalytic processes on a pilot plant scale using different types of radiation (artificial UV or solar UV with a compound parabolic collector). The efficiency of the processes was evaluated by an analysis of the total organic carbon (TOC) removed.The following processes were considered in the study: (i) a photo-Fenton process at an artificial UV pilot plant (with the initial addition of H2O2), (ii) a modified photo-Fenton process with continuous addition of H2O2 and O2 to the system and (iii) a ferrioxalate-assisted solar photo-Fenton process at a compound parabolic collector (CPC) pilot plant. The efficiency of these processes in degrading pollutants has been studied previously, and the results obtained in each of those studies have been published elsewhere. The operational costs due to the consumption of electrical energy, reagents and catalysts were calculated from the optimal conditions of each process.The results showed that the solar photo-Fenton system was economically feasible, being able to achieve up to 75% mineralization with a total cost of 6 €/m3, which can be reduced to 3.6 €/m3 by subtracting the electrical costs because the IGCC plant is self-sufficient in terms of energy.
► Different photocatalytic processes (with artificial or solar UV radiation) were compared. ► The operational costs due to the consumption of electrical energy and reagents were calculated. ► The solar photo-Fenton process is economically a feasible process. ► The treatment cost was 6 €/m3 (for 75% mineralization). ► The cost can be reduced to 3.6 €/m3 because of the energy self-sufficiency of the plant.
