Emission Characteristics, OFPs, and Mitigation Perspectives of VOCs from Refining Industry in China's Petrochemical Bases

China's petroleum refining industry has set off another climax and entered a new rapid development by building seven petrochemical bases. Sector-based volatile organic compound (VOC) emissions from the in petrochemical-developed provinces China were estimated for 1990–2019 projected 2020–2030 under business-as-usual (BAU), policy control (NPC), highest (HC) scenarios. Furthermore, speciated VOCs their ozone formation potentials (OFP) 2019. Total VOC existing refineries 541.14 Gg 2019, of which 43.9%, 31.3%, 18.3%, 6.6% fugitive, end-of-pipe, tank storage, wastewater treatment sources, respectively. Alkanes most dominant refineries, accounting 55.2% total emissions, followed alkenes (18.9%) aromatics (12.5%). Alkenes contributor to OFP, 59.5% alkanes (22.3%) (13.7%). n-Butane, ethylene, cis-2-Butene, n-Decane, n-Pentane top five species with approximately 50% emissions. Whilst, n-Pentane, m/p-Xylene contribution OFPs, 78% OFPs. In 2030, 741.03 165.28 more will be released than 2019 non-control condition BAU scenario. It is that 75.05 228.67 all can reduced NPC 2030 HC To effectively reduce industries, priority should given fugitive improving upgrading production processes implementing enhanced leak detection Repair system. More efficient technologies invented end-of-pipe sources. Vapor recovery systems secondary seals have great potential emission reduction storage tanks.
