Global flaring and venting of petroleum–associated gas is a significant source of greenhouse gas emissions and airborne contaminants that has proven difficult to mitigate over the years. In the petroleum industry, poor efficiency in the flare systems often result in incomplete combustion which produces a variety of volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs) and i...

Nowadays, many companies make a big effort to compete in the global energy market. Although there are many performance improvement strategies that can be implemented by an organization, it is not clear which strategies or combinations are most useful in improving performance.

A flare is a combustion device that uses air or steam to burn associated, unwanted or excess gases and liquids released during production or by pressure relief valves during unplanned over-pressuring of plant equipment in many industrial operations, such as oil-gas extraction, refineries, chemical plants, coal industry and landfills. Several environmental problems caused by gas flaring such as ...

The imposition of environmental regulations, such as greenhouse gas charges, to domestic manufacturing traditionally creates concerns over the impacts of those regulations on international competition and downstream product prices. The US Nitrogen fertilizer industry, an energy-intensive trade-exposed industry, has been considered by conventional metrics to be one of the most vulnerable to such...

High-volume hydraulic fracturing (HVHF) has revolutionized the oil and gas industry worldwide but has been accompanied by highly controversial incidents of reported water contamination. For example, groundwater contamination by stray natural gas and spillage of brine and other gas drilling-related fluids is known to occur. However, contamination of shallow potable aquifers by HVHF at depth has ...

Gender scholars draw on the "theory of gendered organizations" to explain persistent gender inequality in the workplace. This theory argues that gender inequality is built into work organizations in which jobs are characterized by long-term security, standardized career ladders and job descriptions, and management controlled evaluations. Over the past few decades, this basic organizational logi...
