Material Flow and Spatial Data Analysis of the Petroleum Use to Carbon Dioxide (CO₂) Emissions in Northeast China

Abstract

This study investigated the petroleum consumption and petroleum-related CO 2 emissions (PCOEs) in Northeast China at city level using material flow analysis (MFA) and spatial data analysis (SDA). The petroleum flows for the year 2014 were plotted, and then the spatial patterns, weighted mean centers (WMCs), and spatial autocorrelations of petroleum consumption and PCOEs were calculated, respectively. It was found that Northeast China is a petroleum exploitation-processing-export region in China; the total input of petroleum flows comprised two parts-exploitation (about 60%) and import (about 40%). About one third of the total product oil supply flowed into other provinces. In the consumption process, the product oil was dominated by two sectors: the industry sector (45.5%) and the transportation sector (31%). The rate of PCOEs was 36.69 million tonnes in the waste discharge process. Meanwhile, the WMCs of the petroleum consumption and the PCOEs were located in the south of Northeast China. The location of the petroleum pipelines was the factor shown to determine the spatial patterns of petroleum consumption and PCOEs and the hotspots were distributed along the petroleum pipeline, especially in the Circum-Bohai Sea regions. Economic development in these regions shows a positive dependence on petroleum consumption and generates larger PCOEs. The findings obtained in this study could provide important decision-making support to low-carbon development in Northeast China.

“…This research institution works closely with other institutions (Politecnico Milano, Azad University, Sharif University, and the University of Regina), revealing its strong ability to cooperate with other institutions. The China University of Petroleum ranks rst in the number of publications, and its research focuses are CO 2 emission material ow and spatial data analysis in the petrochemical industry, 22 analysis of the effect of natural gas and renewable energy replacing fossil energy on CO 2 emissions, 35,36 development of detection and remediation techniques for VOC leaks in the petroleum industry, 37 and the conversion of CO 2 emissions from the petrochemical industry into methanol and other chemical industrial products to achieve emission reduction and resource utilization. 38 Recent papers reveal that China attaches great importance to the study of PWG, and the research is mainly focused on CO 2 recycling and utilization as well as the establishment of relevant models to evaluate petrochemical emissions, control their escape range, and reduce environmental hazards.…”
