To　effectively　reduce　the　compound　pollution　of　fine　particulate　matter　(PM2.5)　and　ozone　(O-3),　volatile　organic　compound　(VOC)　emission　sources　are　being　extensively　studied.　Studies　on　VOC　emission　characteristics　have　mainly　focused　on　solvent-using　and　technological　sources,　while　research　on　the　combustion　processes　of　high-energy-consuming　industries　remains　limited.　Here,　we　investigate　the　emission　characteristics　of　102　VOC　species　emitted　from　eight　sources　(sintering,　pelletizing,　steel　smelting,　a　coke　oven　chimney,　the　topside　of　a　coke　oven,　thermal　power,　and　two　types　of　cement　kilns)　used　in　four　types　of　high-energy-consuming　industries.　Our　results　show　significant　differences　among　these　sources.　The　average　VOC　mass　concentrations　varied　from　0.14　to　7.08　mg/m(3).　Alkanes　had　the　highest　percentage　contribution　to　VOCs　from　sintering　(45.9%)　and　thermal　power　(44.6%),　while　aromatics　had　the　highest　percentage　contribution　from　steel　smelting　(47.8%)　and　the　topside　of　the　coke　oven　(52.9%).　Alkenes　were　abundant　in　the　coke　oven　chimney　(49.1%),　and　oxygenated　VOCs　accounted　for　65.3%　of　the　total　VOCs　from　pelletizing.　We　also　observed　notable　differences　between　the　two　types　of　cement　kilns.　In　general,　ethane,　ethene,　benzene,　propane,　acetaldehyde,　and　chloromethane　were　the　dominant　VOC　species　in　all　sources.　The　differences　between　the　sources　were　due　to　factors　such　as　the　applied　raw　materials,　calcination　temperature,　and　end-of-pipe　treatment.　By　reviewing　studies　from　the　past　20　years,　we　found　that　differences　in　the　number　of　VOC　species　and　the　implementation　of　ultra-low　emissions　affect　VOC　emission　characteristics.　The　coke　oven　chimney　and　cement　kiln　chimney-1　had　the　highest　ozone　formation　potential　and　secondary　organic　aerosol　potential,　respectively.　The　VOC　emissions　from　coking,　iron　and　steel,　thermal　power,　and　cement　industries　were　1162.1,　289.9,　311.0,　and　470.2　Gg,　respectively.　Our　results　highlight　the　need　for　more　effective　control　measures　to　minimize　VOC　emissions　from　high-energy-consuming　industries.　(C)　2021　Elsevier　B.V.　All　rights　reserved.
