background: the refining process generates large volumes of wastewater containing a variety of chemical contaminants. the use of natural substitutes in treating wastewater which have fewer harmful effects is considered an effective step towards protecting the environment and sustaining the development of these industries. this study focused on the use of moringa oleifera and alum at the wastewa...

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 ...

Iran is very rich in oil and gas, which why the government investing billions of dollars every year gas facilities to improve country. The refinery construction industry are complex involves multidisciplinary contributors. In this environment, many changes claims appear. Changes commonly considered negative events, thus, should be kept away from project. With considering concept, paper presents...

this research was done in order to determine the basic criteria for “tehran oil refinery effluemt treatmentunit” to prove the feasibility of the application of powdered activated carbon in aeration zone of activated sludge system. the main stages of this research included: determination of qualitative and quantitative characteristics of raw wastewater preparation of two pilot scale units of act...

The present study aims for characterization and classification of five different spent petroleum refinery catalysts followed by metal recovery via bioleaching. nomenclature given to the catalyst (SC) is SC1, SC2, SC3, SC4 SC5 collected from an Indian refinery. All were crushed ground prior their X-Ray Fluorescence chemical composition Diffraction Scanning Electron Microscopy-Energy Dispersive S...

The fundamental purpose of the petroleum refining industry is to convert crude oil into refined products comprising more than 2,500 substances. Among are liquefied gasoline, aviation fuel, kerosene, fuel oils, diesel lubricating and feedstocks, which have a variety uses in petrochemical other industries. refinery process begins with storage continues handling operations before concluding separa...
