Caustic scrubbing is a technology that has been used for the removal of H2S and other acid species from gases in different industries for many years. Improvements in design and control strategies, favorable prices for caustic compared with other non-regenerable H2S scavenging chemicals, and the potential for sales value for the NaHS (sodium bisulfide) product have made caustic scrubbing an econ...

background: the objectives of this paper are three folds. first, an integrated framework for designing and development of the integrated health, safety and environment (hse) model is presented. second, it is implemented and tested for a large gas refinery in iran. third, it is shown whether the total ergonomics model is superior to the conventional ergonomics approach. this study is among the f...

background: millions of workers are the victims of different kinds of accidents every year throughout the world. the purpose of this study was to investigate the relationships between safety attitude and occurrence of the occupational accidents. methods: this investigation was a cross-sectional study performed in a gas refinery in south of iran in 2008. sample size of this study was 176 people....

A rise in CO2 and other greenhouse gases’ concentration from gas refinery flares and furnaces in the atmosphere causes environmental problems. In this work, a new process was designed to use waste gas (flue gas and flare gas) of a domestic gas refinery to produce pure hydrogen in a membrane reactor. In particular, the process foresees that the energy and CO2 content of flue gas can provide the ...

in this paper, using the value efficiency in dea pattern by taking decisive obtain. generally, non-radial model of ve and use proper weight to reduce input and output gain are the appropriate pattern. this paper introduces a multi-objective linear programming problem and efficiency determines the value of inefficient units. use interactive methods to solve molp proposed and applied. in conclusi...

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...

Nowadays, air pollution is one of the major challenges in Assaluyeh, therefore, in the present study, according to the importance of the fourth refinery gas as the largest gas refinery in the region, the amount of emissions from Stacks and flares has been initially determined and then the distribution has been identified in the region. In this research, AERMOD and CALPUFF models have been used ...

Chemical-Looping Combustion (CLC) is an emerging technology for CO2 capture because separation of this gas from the other flue gas components is inherent to the process and thus no energy is expended for the separation. Natural or refinery gas can
