The present work deals with optimization of culture conditions and process parameters for bioleaching of spent petroleum catalyst collected from a petroleum refinery. The efficacy of Ni bioleaching from spent petroleum catalyst was determined using pure culture of Acidithiobacillus thiooxidans DSM- 11478. The culture conditions of pH, temperature and headspace volume to media volume ratio were ...

Pipelines provide an economic fluid transportation mode for petroleum systems, especially when large amounts of petroleum derivatives have to be pumped for long distances. The system reported in this paper is composed by an oil refinery, one multiproduct pipeline connected to several depots and to the local consumer markets that receive large amounts of oil products. Extensive distances must be...

Experimental assessment of process kinetic is essential for modelling and can serve as a useful tool to improve performance. In this study, evaluation petroleum refinery wastewater (PRWW) biodegradation in an activated sludge (ASP) was carried out 25 L ASP reactor which operated within the conventional aeration mode 2-10 hours, hydraulic retention time (HRT), effluents from secondary sedimentat...

Abstract The present experimental study used a successful advanced electrochemical oxidation process (AEOP) and parallel-plate reactor to investigate the potential of (EO) treatment method for real produced wastewater by Al-Samawah petroleum refinery. In oxidation, several electrodes type were employed, with carbon felt graphite plate serving as anode. Tests total organic compounds chemical oxy...
