industrial wastewaters are of the major sources of heavy metal pollution in the environment. in the middle east, gas and oil industry is the major source of heavy metal pollution and releases significant amounts of metals into the terrestrial and aquatic environment. in this research the capability of the common reed ( phragmitis australis ) in absorbing heavy metals cd, pb and v from the waste...

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...

We introduce two generalized condensation principles: Local Club Condensation and Stationary Condensation. We show that while Strong Condensation (a generalized Condensation principle introduced by Hugh Woodin in [19]) is inconsistent with an ω1-Erdős cardinal, Stationary Condensation and Local Club Condensation (which should be thought of as weakenings of Strong Condensation) are both consiste...
