In the Persian Gulf region, conditions are highly favorable for ozone air pollution and the region is a hot spot of photochemical smog. The vast activities in processing oil and gas play a major role in it. It was found that the elevated concentrations of reactive hydrocarbons co-emitted with nitrogen oxides from Hydrocarbon Processing facilities lead to substantial ozone production. South Pars...

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...

Methane is an important greenhouse gas due to its high warming potential. While quantifying anthropogenic methane emissions is important for evaluation measures applied for climate change mitigation, large emission uncertainties still exist for many source categories. To evaluate anthropogenic methane emission inventory in various regions over the globe, we extract emission signatures from colu...

A fuel-based methodology for calculating motor vehicle emission inventories is presented. In the fuel-based method, emission factors are normalized to fuel consumption and expressed as grams of pollutant emitted per gallon of gasoline burned. Fleet-average emission factors are calculated from the measured on-road emissions of a large, random sample of vehicles. Gasoline use is known at the stat...

0. The paper describes a bottom-up development and evaluation of a highly-resolved regional emission inventory for NMHCs in the area of Jiangsu, a strong industrialized region in Eastern China. The reference period is almost 10 years. The quantification of chemical processes is based on the determination of realistic source profiles for industrial activities by near-source measurements. The aut...

In this paper, we present a dynamic model modified with emission permit banking and pollution abatement, and investigate the effect of emission permit banking and pollution abatement on the production–inventory strategy of the firm. After introducing emission permit banking and pollution abatement, the cost function consists of the inventory holding and production costs, the cost of investment ...

The Sparse Matrix Operator Kernel Emissions (SMOKE) modeling system has been integrated with the Environmental Protection Agency's Models-3 air quality modeling system. This paper provides an overview of the emission processing capabilities of the revised SMOKE system (version 1.0), and describes how they can benefit the air quality modeling community. Like the SMOKE prototype, SMOKE version 1....
