In contrast to past regulations for power plant air pollutants, there is growing interest in a multi-pollutant perspective that would simultaneously address criteria pollutants, air toxics, and greenhouse gases. This paper addresses some of the key technical and economic questions needed to assess policy proposals, namely: What technical options are available to control each of these pollutants...

Chlorine, one of the most abundant elements in nature, undergoes a complex biogeochemical cycle in the environment, involved in the formation of volatile organochlorines (VOCls), which in turn can contribute to environmental problems, contaminate natural ecosystems, and are of public health concern. Several industrial and natural sources of VOCls have already been identified; however, data – pa...

The paper addresses the problem of real-time emission control in a given set of air pollution sources. The approach applied utilizes the optimal control technique for distributed parameter systems. A set of pointwise emission sources with a predefined location and emission characteristics is considered as the controlled object. The problem is formulated as on-line minimization of an environment...

Plants undergoing heat and low-CO2 stresses emit large amounts of volatile isoprenoids compared with those in stress-free conditions. One hypothesis posits that the balance between reducing power availability and its use in carbon assimilation determines constitutive isoprenoid emission rates in plants and potentially even their maximum emission capacity under brief periods of stress. To test t...

The South Pars zone in Iran encompasses the largest gas refineries and petrochemical complexes in the world. In the South Pars zone, elevated concentrations of reactive hydrocarbons co-emitted with nitrogen oxides from industrial facilities lead to substantial ozone production downwind. To understand the role of these emissions on the ozone formation and, to formulate appropriate control st...

In China, coal combustion to generate electric power is the primary method, the energy-saving and emission reduction is the urgent task. At present, the energy-saving dispatching trial method in some area evaluates energy-saving and emission reduction of coal combustion power generation according to power supply coal consumption rate only. But the power supply coal consumption rate can’t reflec...

The present study presents a framework to include environmental externalities into a system of national accounts. The paper develops estimates of air pollution damages for each industry in the United States. The first section proposes a framework for national economic accounting that values pollution using marginal damages. An integrated-assessment model (the Air Pollution Emission Experiments ...

In the paper the problem of the real-time emission control is discussed, where the air quality forecast is based on the regional-scale model of air pollution transport. The problem formulation utilizes the optimal control technique for distributed parameter systems, which is integrated with the governing equations of air pollution dispersion process. The approach presented in the paper is sulfu...

This paper a Multi-objective Honey Bee Mating Optimization (MOHBMO) is proposed for Environmental/ Economic Power Dispatch (EED) problem. This paper proposes a new environmental/economic load dispatch model that considers cost and emission function coefficients with uncertainties and the constraints of ramp rate. Due to the environmental concerns that arise from the emissions produced via fossi...
