As a highly energy-intensive and carbon-emitting industry with significant emissions of volatile organic compounds (VOCs), the petroleum and chemical industry is a major contributor to global greenhouse effect and ozone layer destruction. Improper treatment of petrochemical waste gas (PWG) seriously harms human health and the natural environment. This study uses CiteSpace and VOSviewer to conduct a scientometric analysis of 1384 scholarly works on PWG and carbon sequestration published between 1981 and 2022, revealing the basic characteristics, knowledge base, research topic evolution, and research hotspots of the field. The results show: 1) In the early stages of the petrochemical industry, it was combustion flue gas, not process tail gas or plant leakage waste gas, that was given the top priority in PWG research. 2) Later, researchers studied the emission model of PWG (such as VOCs) and the treatment and recovery technology of PWG (condensation, pyrolysis, membrane separation, and adsorption methods). Pyrolysis is one of the main treatment methods for PWG at present, but insufficient combustion may lead to secondary pollution. 3) In recent years, research has centered on using new energy to replace fossil energy to reduce the PWG and carbon emissions of the petrochemical industry in the context of the Paris Agreement, and the number of publications related to this topic has increased rapidly. The results of our analysis can provide funding agencies and research groups with information to better understand the global trends and directions that have emerged in this field from 1981 to 2022 and serve as a reference for future research.

“…Petrochemical industry Certain procedures in petrochemical industry have been identified as the main contributors to AVOCs emissions from the sector. For example, equipment leaks, storage tanks, and manufacturing lines were estimated to be responsible for over 90% of the total emissions (Ke et al, 2020;Liu et al, 2020;Yen and Horng, 2009). Through field measurements and in-depth analysis of different emission calculation methods, Zhang et al (2021a) suggested that procedure-based method should provide better estimate of NMVOCs emissions for petroleum industries than the commonly approach that applied a full emission factor for the whole factory.…”

Abstract. China has been conducting a series of actions on air quality improvement for the past decades, and air pollutant emissions have been changing swiftly across the country. Province is an important administrative unit for air quality management, thus reliable provincial-level emission inventory for multiple years is essential for detecting the varying sources of pollution and evaluating the effectiveness of emission controls. In this study, we selected Jiangsu, one of the most developed provinces in China, and developed the high-resolution emission inventory of nine species for 2015–2019, with improved methodologies for different emission sectors, best available facility-level information on individual sources, and real-world emission measurements. Resulting from implementation of strict emission control measures, the anthropogenic emissions were estimated to have declined 53 %, 20 %, 7 %, 2 %, 10 %, 21 %, 16 %, 6 % and 18 % for SO2, NOX, CO, NMVOCs, NH3, PM10, PM2.5, BC, and OC from 2015 to 2019, respectively. Larger abatement of SO2, NOX and PM2.5 emissions were detected for the more developed southern Jiangsu. Since 2016, the ratio of biogenic volatile organic compounds (BVOCs) to anthropogenic volatile organic compounds (AVOCs) exceeded 50 % in July, indicating the importance of biogenic sources on summer O3 formation. Our estimates in annual emissions of NOX, NMVOCs, and NH3 were generally smaller than the national emission inventory MEIC, but larger for primary particles. The discrepancies between studies resulted mainly from different methods of emission estimation (e.g., the procedure-based approach for AVOCs emissions from key industries used in this work) and inconsistent information of emission source operation (e.g., the penetrations and removal efficiencies of air pollution control devices). Regarding the different periods, more reduction of SO2 emissions was found between 2015 and 2017, but NOX, AVOCs and PM2.5 between 2017 and 2019. Among the selected 13 major measures, the ultra-low emission retrofit on power sector was the most important contributor to the reduced SO2 and NOX emissions (accounting for 38 % and 43 % of the emission abatement, respectively) for 2015–2017, but its effect became very limited afterwards as the retrofit had been commonly completed by 2017. Instead, extensive management of coal-fired boilers and upgradation and renovation of non-electrical industry were the most important measures for 2017–2019, accounted collectively for 61 %, 49 % and 57 % reduction of SO2, NOX and PM2.5, respectively. Controls on key industrial sectors maintained the most effective for AVOCs reduction for the two periods, while measures on other sources (transportation and solvent replacement) became increasingly important for more recent years. Our provincial emission inventory was demonstrated to be supportive for high-resolution air quality modeling for multiple years. Through scenario setting and modeling, worsened meteorological conditions were found from 2015 to 2019 for PM2.5 and O3 pollution alleviation. However, the efforts on emission controls were identified to largely overcome the negative influence of meteorological variation. The changed anthropogenic emissions were estimated to contribute 4.3 and 5.5 μg·m-3 of PM2.5 concentration reduction for 2015–2017 and 2017–2019, respectively. While elevated O3 by 4.9 μg·m-3 for 2015–2017, the changing emissions led to 3.1 μg·m-3 of reduction for 2017–2019, partly (not fully though) offsetting the meteorology-driven growth. The analysis justified the validity of local emission control efforts on air quality improvement, and provided scientific basis to formulate air pollution prevention and control policies for other developed regions in China and worldwide.

“…Some have been classified as carcinogens, such as formaldehyde, benzene, chlorotoluene [5,6] . The formation of haze and photochemical smog, which cause secondary pollution in the atmosphere, is the main hazard of VOCs to the atmosphere [7,8] . According to the research on wood drying at home and abroad, the VOCs produced during wood drying can be roughly divided into two categories: terpenoids and non‐terpenoid volatiles [9,10] …”

This work reported the synthesis of Ce-MOF and Nd-MOF adsorption materials using the solvothermal method with the rare earth metals Ce 3 + and Nd 3 + as the particle center and discussed the adsorption effect of the two synthesized nanomaterials on the VOCs released by dry wood. The porous morphology of the material increases the benzene gas contact area. The maximum adsorption capacity of benzene, according to the Langmuir model, is 128.98 mg/g and 132.22 mg/g, respectively. The method has a large adsorption capacity, good adsorption effect, non-toxic and harmless, low recycling cost, recyclable multiple times, simple operation, stable structure, no secondary environmental pollution, etc., and has good application prospects in the wood drying industry.
