  "text": "For the purposes of these BAT conclusions, the following acronyms and definitions apply.\nCommission Implementing Decision 2012/119/EU of 10 February 2012 laying down rules concerning guidance on the collection of data and on the drawing up of BAT reference documents and on their quality assurance referred to in Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions (OJ L 63, 2.3.2012, p. 1).\nTerm used\nDefinition\nBAT-AEPL\nEnvironmental performance level associated with BAT, as described in Commission Implementing Decision 2012/119/EU. BAT-AEPLs include emission levels associated with the best available techniques (BAT-AELs) as defined in Article 3(13) of Directive 2010/75/EU\nBTX\nCollective term for benzene, toluene and ortho-/meta-/para-xylene or mixtures thereof\nCO\nCarbon monoxide\nCombustion unit\nAny technical apparatus in which fuels are oxidised in order to use the heat thus generated. Combustion units include boilers, engines, turbines and process furnaces/heaters, but do not include waste gas treatment units (e.g. a thermal/catalytic oxidiser used for the abatement of organic compounds)\nContinuous measurement\nMeasurement using an ‘automated measuring system’ permanently installed on site\nContinuous process\nA process in which the raw materials are fed continuously into the reactor with the reaction products then fed into connected downstream separation and/or recovery units\nCopper\nThe sum of copper and its compounds, in dissolved or particulate form, expressed as Cu\nDNT\nDinitrotoluene\nEB\nEthylbenzene\nEDC\nEthylene dichloride\nEG\nEthylene glycols\nEO\nEthylene oxide\nEthanolamines\nCollective term for monoethanolamine, diethanolamine and triethanolamine, or mixtures thereof\nEthylene glycols\nCollective term for monoethylene glycol, diethylene glycol and triethylene glycol, or mixtures thereof\nExisting plant\nA plant that is not a new plant\nExisting unit\nA unit that is not a new unit\nFlue-gas\nThe exhaust gas exiting a combustion unit\nI-TEQ\nInternational toxic equivalent – derived by using the international toxic equivalence factors, as defined in Annex VI, part 2 to Directive 2010/75/EU\nLower olefins\nCollective term for ethylene, propylene, butylene and butadiene, or mixtures thereof\nMajor plant upgrade\nA major change in the design or technology of a plant with major adjustments or replacements of the process and/or abatement units and associated equipment\nMDA\nMethylene diphenyl diamine\nMDI\nMethylene diphenyl diisocyanate\nMDI plant\nPlant for the production of MDI from MDA via phosgenation\nNew plant\nA plant first permitted on the site of the installation following the publication of these BAT conclusions or a complete replacement of a plant following the publication of these BAT conclusions\nNew unit\nA unit first permitted following the publication of these BAT conclusions or a complete replacement of a unit following the publication of these BAT conclusions\nNOX precursors\nNitrogen-containing compounds (e.g. ammonia, nitrous gases and nitrogen-containing organic compounds) in the input to a thermal treatment that lead to NOX emissions. Elementary nitrogen is not included\nPCDD/F\nPolychlorinated dibenzo-dioxins and -furans\nPeriodic measurement\nMeasurement at specified time intervals using manual or automated methods\nProcess furnace/heater\nProcess furnaces or heaters are:\ncombustion units whose flue-gases are used for the thermal treatment of objects or feed material through direct contact, e.g. in drying processes or chemical reactors; or\ncombustion units whose radiant and/or conductive heat is transferred to objects or feed material through a solid wall without using an intermediary heat transfer fluid, e.g. furnaces or reactors heating a process stream used in the (petro-)chemical industry such as steam cracker furnaces.\nIt should be noted that, as a consequence of the application of good energy recovery practices, some of the process furnaces/heaters may have an associated steam/electricity generation system. This is considered to be an integral design feature of the process furnace/heater that cannot be considered in isolation.\nProcess off-gas\nThe gas leaving a process which is further treated for recovery and/or abatement\nNOX\nThe sum of nitrogen monoxide (NO) and nitrogen dioxide (NO2), expressed as NO2\nResidues\nSubstances or objects generated by the activities covered by the scope of this document, as waste or by-products\nRTO\nRegenerative thermal oxidiser\nSCR\nSelective catalytic reduction\nSMPO\nStyrene monomer and propylene oxide\nSNCR\nSelective non-catalytic reduction\nSRU\nSulphur recovery unit\nTDA\nToluene diamine\nTDI\nToluene diisocyanate\nTDI plant\nPlant for the production of TDI from TDA via phosgenation\nTOC\nTotal organic carbon, expressed as C; includes all organic compounds (in water)\nTotal suspended solids (TSS)\nMass concentration of all suspended solids, measured via filtration through glass fibre filters and gravimetry\nTVOC\nTotal volatile organic carbon; total volatile organic compounds which are measured by a flame ionisation detector (FID) and expressed as total carbon\nUnit\nA segment/subpart of a plant in which a specific process or operation is carried out (e.g. reactor, scrubber, distillation column). Units can be new units or existing units\nValid hourly or half-hourly average\nAn hourly (or half-hourly) average is considered valid when there is no maintenance or malfunction of the automated measuring system\nVCM\nVinyl chloride monomer\nVOCs\nVolatile organic compounds as defined in Article 3(45) of Directive 2010/75/EU",
