  "heading": "In order to reduce emissions of organic compounds to air from wood and wood products preservation using creosote, BAT is to enclose emitting equipment or processes (e.g. storage and impregnation tanks, depressurisation, creosote reconditioning), extract the off-gases and use one or a combination of the treatment techniques given below.",
  "text": "Technique\nDescription\nApplicability\n(a)\nThermal oxidation\nSee BAT 15 (i). Exhaust heat can be recovered by means of heat exchangers.\nGenerally applicable.\n(b)\nSending off-gases to a combustion plant\nPart or all of the off-gases are sent as combustion air and supplementary fuel to a combustion plant (including CHP (combined heat and power) plants) used for steam and/or electricity production.\nNot applicable for off-gases containing substances referred to in IED Article 59(5). Applicability may be restricted due to safety considerations.\n(c)\nAdsorption using activated carbon\nOrganic compounds are adsorbed on the surface of activated carbon. Adsorbed compounds may be subsequently desorbed, e.g. with steam (often on site) for reuse or disposal and the adsorbent is reused.\nGenerally applicable.\n(d)\nAbsorption using a suitable liquid\nUse of a suitable liquid to remove pollutants from the off-gases by absorption, in particular soluble compounds.\nGenerally applicable.\n(e)\nCondensation\nA technique for removing organic compounds by reducing the temperature below their dew points so that the vapours liquefy. Depending on the operating temperature range required, different refrigerants are used, e.g. cooling water, chilled water (temperature typically around 5 °C), ammonia or propane.\nCondensation is used in combination with another abatement technique.\nApplicability may be restricted where the energy demand for recovery is excessive due to the low VOC content.\nTable 36\nBAT-associated emission levels (BAT-AELs) for TVOC and PAH emissions in waste gases from wood and wood products preservation using creosote and/or solvent-based treatment chemicals\nThe BAT-AEL refers to the sum of the following PAH compounds: acenaphthene, acenaphthylene, anthracene, benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(g,h,i)perylene, benzo(k)fluoranthene, chrysene, dibenzo(a,h)anthracene, fluoranthene, fluorene, indeno(1,2,3-cd)pyrene, naphthalene, phenanthrene and pyrene.\nParameter\nUnit\nProcess\nBAT-AEL(Average over the sampling period)\nTVOC\nmg C/Nm3\nCreosote and solvent-based treatment\n< 4–20\nPAHs\nmg/Nm3\nCreosote treatment\n< 1\nThe associated monitoring is given in BAT 45.",
