Removal of sulfur compounds from petroleum refinery wastewater through adsorption on modified activated carbon

The adsorption of sulfur compounds from petroleum refinery wastewater on a chemically modified activated carbon (MAC) was investigated. The modification technique (nitric acid, hydrogen peroxide and thermal modification) enhanced the removal capacity of carbon and therefore decreases cost-effective removal of sulfide from refinery wastewater. Adsorption equilibrium and kinetics data were ...

Adsorption of polycyclic aromatic hydrocarbons from wastewater by using silica-based organic–inorganic nanohybrid material

Polycyclic aromatic hydrocarbons (PAHs) are a group of priority pollutants, which are classified as persistent hazardous contaminants. Herein, the adsorption of three PAHs, naphthalene (NAP), acenaphthylene (ACN), and phenanthrene (PHN), from wastewater onto NH2-SBA-15 organic–inorganic nanohybrid material as a function of pH of the media (2–10), sorbent dosage (0.5–3.5 g ...

Treatment of petroleum refinery wastewater using a sequential anaerobic–aerobic moving-bed biofilm reactor system based on suspended ceramsite

In this study, a novel suspended ceramsite was prepared, which has high strength, optimum density (close to water), and high porosity. The ceramsite was used to feed a moving-bed biofilm reactor (MBBR) system with an anaerobic–aerobic (A/O) arrangement to treat petroleum refinery wastewater for simultaneous removal of chemical oxygen demand (COD) and ammonium. The hydraulic retention ...

Biodegradation of phenol in refinery wastewater by pure cultures of Pseudomonas aeruginosa NCIB 950 and Pseudomonas fluorescence NCIB 3756

The potential of microorganisms to catabolise and metabolise xenobiotic compounds has been recognised as a potentially effective means of toxic and hazardous wastes disposal. Phenol and its derivatives have long been recognised as some of the most persistent chemicals in petroleum refinery wastewaters, with high toxicity even at low concentrations. Biodegradation of these compounds has been ...

Evaluating photo-degradation of COD and TOC in petroleum refinery wastewater by using TiO2/ZnO photo-catalyst

The aim of this study is to investigate the performance of combined solar photo-catalyst of titanium oxide/zinc oxide (TiO2/ZnO) with aeration processes to treat petroleum wastewater. Central composite design with response surface methodology was used to evaluate the relationships between operating variables for TiO2 dosage, ZnO dosage, air flow, pH, and reaction time to identify the optimum ...

Treatment of petroleum refinery wastewater by distillation-assisted catalytic oxidation under low temperature and low pressure

A distillation-assisted catalytic oxidation (DACO) process under low temperature (100 °C) and atmospheric pressure was investigated to treat heavily contaminated wastewater from oil refining industry. The DACO experiments were carried out in a distillation batch reactor, using CuO/γ-A12O3 as catalyst. The experimental temperature was kept at 100 °C and H2O2 oxidant was supplied into the reactive ...

Water Use and Reuse in Petroleum Refining

Refineries can be like cities, and opportunities for water reuse abound, from recycling of process water to sewage Although the water requirements of oil exploration make water reuse a hot topic for the upstream petroleum industry — the exploration and production end — there are significant opportunities for reuse downstream, which includes refining. Petroleum refineries are ...

An integrated approach for source contribution estimation: a case study

The efficiency of the CMB model for source contribution estimate is determined by the availability of accurate source profiles and therefore its use is limited when source profiles are not known. In this study the source contribution estimate of ambient VOC was carried out using the CMB model with the source profiles obtained from the PMF model. The PMF model fitted the monitored dataset very ...

PeCOD – Petrochemical Industry - Case Study

Optimizing process efficiency for petrochemical wastewater monitoring is a key step in achieving sustainable energy. Care must be taken to properly monitor and treat wastewater generated from petroleum refineries to ensure contaminants are not released into the surrounding environment. Fast, safe, and reliable detection technology is therefore highly sought after and enables plant operators to ...
