Cryogenic air separation technology has been successfully employed for many years to supply oxygen for the gasification of a wide range of hydrocarbon feedstocks to generate synthesis gas for the production of fuels, chemicals and other valuable products. Examples include the conversion of liquid and solid refinery waste streams into hydrogen for use within the refinery Ž . along with the copro...

BACKGROUND This study investigated the relationship between people's attitudes towards the safety culture and comparing its perceptions among three levels of refinery Personnel: top management, supervisory staff and frontline workers by conducting safety culture survey. METHODS A questionnaire comprising general information and 59-safety attitude statement were distributed among 237 workers, ...

he 1980s brought changing trends into the waste market with increased reclamation, T recycling and waste minimization efforts. Adapting proven tcchnologies has aided in moving these three forms of waste managcment forward. A t EncycleITexas, Inc. (ETI), the fundamental objcctive of recycling is to convert hazardous waste into products. Founded in 1988, ET1 recycles metalbearing waste streams to...

Moderate effects of pollution on health may exert an important influence on labor market decisions. We exploit exogenous variation in pollution due to the closure of a large refinery in Mexico City to understand how pollution impacts labor supply. The closure led to an 8 percent decline in pollution in the surrounding neighborhoods. We find that a one percent increase in sulfur dioxide results ...

The microalgal community as primary producers has to play a significant role in the biotic and abitoic interactions of any aquatic ecosystem. Whenever a community is exposed to a pollutant, responses can occur because individuals acclimate to pollutant caused changes and selection can occur favouring resistant genotypes within a population and selection among species can result in changes in co...

The energy industry and in particular the Oil Refineries are extremely important elements in Iraq’s infrastructure. A terrorist attack on one oil refinery will have a catastrophic impact on oil production and the whole economy. It can also cause serious damage to the environment and even losses of human lives. The security of information systems and industrial control systems such as Supervisor...

To study the migration and variation rule of petroleum pollutants in soil evaluate condition, field investigation is carried out a refinery Yunnan Province relevant data are collected. Then, sampling leaching experiments on land refinery. Finally, experimental sorted out. The results show that pollution surface most serious. Because adsorb-ability soil, content deep less. diffusion process grea...

Advances in sensors, automation, and information technology have significantly changed the way refineries operate. High performance computing in physically small devices and high speed communication technology developments have been the foundation for many of these advances. Advanced analytical and optimization methods based on this infrastructure can simultaneously lower costs, increase profit...

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...
