A chemical engineering approach for the rigorous construction, solution, and optimization of detailed kinetic models for biological processes is described. This modeling capability addresses the required technical components of detailed kinetic modeling, namely, the modeling of reactant structure and composition, the building of the reaction network, the organization of model parameters, the so...

In this present study the dissolved air flotation (DAF) system was investigated for the treatment of Kermanshah Oil Refinery wastewater. The effect of three parameters on flotation efficiency including of flow rate (outflow from the flotation tank), saturation pressure and coagulant dosage on chemical oxygen demand (COD) removal was examined experimentally. All the experiments were done under a...

Oil and gas field wastewater or produced water is a significant waste stream in the oil and gas industries. In this study, the performance of a membrane sequencing batch reactor (MSBR) and membrane sequencing batch reactor/reverse osmosis (MSBR/RO) process treating produced wastewater were investigated and compared. The MSBR was operated in different hydraulic residence time (HRT) of 8, 20 and ...

Submit Manuscript | http://medcraveonline.com J Microbiol Exp 2015, 2(3): 00048 are the main oil constituent release by industrial and domestic sources, accumulation of dispensed oil and oil derivatives released, separated in oil Refinery and from storage tanks create huge environmental hazard [1-4]. Therefore controlled and monitoring system was adapted to prevent the release of hydrocarbon in...

The main objective of this study is to identify the inherent benefits associated with integrating a new petrochemical facility existing refinery. Petrochemical complexes heavily rely on feedstocks like naphtha and refinery gases, which are frequently produced in oil refineries, ensuring reliable supply essential raw materials. Integration between becomes necessary due their downstream position ...

Kaewchai, S. and Prasertsan, P. Screening and application of thermotolerant microorganisms and their flocculant for treatment of palm oil mill effluent Songklanakarin J. Sci. Technol., 2002, 24(3) : 413-420 Among fifteen thermotolerant polymer-producing isolates, three strains SM 29, WD 90, and SM 38 produced polymer posessing very high flocculating activities (24.81, 14.63 and 10.84, respectiv...

Naphthenic acids and TAN are one of the ever-increasing crucial problems in oil, shale oil and sand oil industry and also environment protection. Furtherer, they increases the corrosion of some parts of a refinery and transport pipelines and also can create nanoemulsions and make complicated the refining process especially in desalters. To prevent these problems it is important to first obtain ...

Application of Granular Activated Carbon (GAC) in adsorption process has been studied for the advanced treatment of municipal and industrial wastewater. Because of entering poisonous compounds such as furfural, phenol and sulfides into the oily wastewater of Tehran refinery, biological aeration basins of wastewater treatment unit may not have the desired performance of COD reduction. In this st...

For the first time, this work investigates achievability of developing a biorefinery concept around almond hulls by hydrothermal treatment (HTT), thoroughly scrutinising influence temperature (200–300 °C), pressure (100–180 bar), time (20–180 min) and solid loading (5–25 wt%). This process allowed conversion into four main products: gas (2–13%), bio-oil (2–12%), aqueous (4–69%) hydro-char (17–8...

This paper presents chemical composition and aquatic toxicity characteristics of a commercial sample of naphthenic acids (NAs). Naphthenic acids are derived from the refining of petroleum middle distillates and can contribute to refinery effluent toxicity. NAs are also present in oil sands process-affected water (OSPW), but differences in the NAs compositions from these sources precludes using ...
