Control VOC`s in Refinery Wastewater

Oil and water do not mix, like many of life’s one-liners this statement is basically true but not the whole story. Many hydrocarbon liquids, particularly aromatics, have significant solubilities in water: Benzene 1800 PPMVToluene 470Ethyl Benzene 150Xylenes 150 Petroleum refineries do not like salts in their feedstock since these corrode and foul process equipment. The first refining step is ...

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 ...

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 ...

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 time ...

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 ...

Wastewater Treatment & Recycle

Fresh water is a scarce commodity; this fact is well acknowledged by one and all. People at all levels be it general public, governmental bodies, and industries understand the implications of good quality water availability in terms of quantity, cost and wastage. As a consequence, there is a growing consensus on wastewater treatment for recycle/reuse. This paper briefly describes the treatment ...

MBBR system performance improvement for petroleum hydrocarbon removal using modified media with activated carbon

Moving bed biofilm reactor (MBBR) system has a successful operation in the treatment of different types of wastewater. Since the media, i.e. the place of growth and formation of biofilm, play the main role in the treatment in this system, MBBR systems were operated in the present research with modified Bee-cell media. Activated carbon granules of almond or walnut shells were placed in media ...

Starndard Batch Treatment of Free and Soluble Oil Wastewater

Small and Medium metal-based manufacturing plants produce between 1,000 and 30,000 gallons per week of oil-laden wastewater. Typically, the oil load is less then 2,000mg/l as soluble oil. Free (globular) oil is typically removed by DAF, oil-water separator, or coalescer with the remaining soluble oil needing to be reduced to less then 100mg/l in order to discharge directly to the local sewerage ...

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 ...
