Abstract
With the rapid development of China’s container port industry, the emissions of air pollutants in port areas have been increasing. Cargo handling equipment as a non-road mobile source of emissions has become a focus of public attention. This article adopted a full activity-based “bottom-up” method to establish the inventory of emissions by cargo handling equipment at a container port. Drawing on the OFFROAD model, we conducted investigation and analysis of cargo handling equipment holdings, activity levels, and equipment-related parameters and modified the emission factors. The Nanjing Longtan Container Port was taken as a case study. Results show that in 2014, emissions by cargo handling equipment of the Nanjing Longtan Container Port were as follows: PM10 4.25 t, PM2.5 3.91 t, NOx 82.98 t, SOx 1.06 t, CO 23.84 t, and HC 16.39 t, all lower than results from an earlier research based on 2013 fuel consumption data. Cargo handling equipment produced more PM and HC emissions than any other emission source at the port. The method and main conclusions of this article provide support for future work on energy conservation and emission reduction in port areas.
Highlights
With the rapid development of China’s container port industry, the emissions of air pollutants in port areas have been increasing
Based on power, equipment’s engine activity, fuel type, and engine type—to calculate EU non-road mobile source emissions of atmospheric pollutants in 1990, compared the results with pollutant emissions of onroad mobile sources, and proved that non-road emissions were a major source of atmospheric pollution; Kean et al.[9] estimated NOx and PM emissions of non-road mobile sources of the United States of 1996 with the method based on fuel consumption; M Lindgren and PA Hansson[10] studied the effects of transient operating conditions on emissions of non-road diesel engine and it was concluded that the air fuel ratio had an important influence on the formation of the College of Harbour, Coastal and Offshore Engineering, Hohai University, Nanjing, China
The local pollutant emission factor was selected on the basis of the field investigation results of various cargo handling equipment (CHE) in Nanjing Longtan Container Port (NLCP)
Summary
With the rapid development of China’s container port industry, the emissions of air pollutants in port areas have been increasing. The local pollutant emission factor was selected on the basis of the field investigation results of various CHE in Nanjing Longtan Container Port (NLCP).
