Life-cycle production optimization of hydrocarbon fields: thermoeconomics perspective

Investigation on life cycle assessment of lead and zinc production

Lead and zinc production is one of the main predisposing factors of excessive greenhouse gases emissions, air pollution and water consumption. In this paper, the environmental problems of lead and zinc production in Calcimin plant are expressed and life cycle assessment of this plant is assessed. The data regarding the amount of induced global warming and pollution, acidification, and depletion...

Life-Cycle Assessment of Environmental Effects on Rapeseed Production

In recent years, increasing the awareness on the environmental problems, especially global warming, has increase the concerns about the impact of emissions on the global climate. The current study was conducted to evaluate and analyze the environmental effects of rapeseed production in the form of life cycle using SimaPro software with the aim concentration on climate changes and impact of acid...

Contribution of cyanobacterial alkane production to the ocean hydrocarbon cycle.

Hydrocarbons are ubiquitous in the ocean, where alkanes such as pentadecane and heptadecane can be found even in waters minimally polluted with crude oil. Populations of hydrocarbon-degrading bacteria, which are responsible for the turnover of these compounds, are also found throughout marine systems, including in unpolluted waters. These observations suggest the existence of an unknown and wid...

Adult Equivalence Scales: A Life-Cycle Perspective

In any policy-orientated study of family welfare, it is inevitable that some comparison of welfare between households with different compositions will be required, and the theory of (adult) equivalence scales aims to formalise the way in which these comparisons may be made. An adult equivalence scale is defined as the proportionate increase in income per adult necessary to maintain a certain le...
