  "text": "BAT is to reduce emissions from downstream processes by using one or a combination of the following techniques:\nA description of the techniques is given in Sections 1.10.7 and 1.10.9.\nTechnique\nApplicability\n(i)\nImpact jets and cyclones\nThe technique is based on the removal of particles and droplets from waste gases by impaction/impingement, as well as gaseous substances by partial absorption with water. Process water is normally used for impact jets. The recycling process water is filtered before it is reapplied\nThe technique is generally applicable to the mineral wool sector, in particular to glass wool processes for the treatment of emissions from the forming area (application of the coating to the fibres).\nLimited applicability to stone wool processes since it could adversely affect other abatement techniques being used.\n(ii)\nWet scrubbers\nThe technique is generally applicable for the treatment of waste gases from the forming process (application of the coating to the fibres) or for combined waste gases (forming plus curing)\n(iii)\nWet electrostatic precipitators\nThe technique is generally applicable for the treatment of waste gases from the forming process (application of the coating to the fibres), from curing ovens or for combined waste gases (forming plus curing)\n(iv)\nStone wool filters\nIt consists of a steel or concrete structure in which stone wool slabs are mounted and act as a filter medium. The filtering medium needs to be cleaned or exchanged periodically. This filter is suitable for waste gases with a high moisture content and particulate matter with an adhesive nature\nThe applicability is mainly limited to stone wool processes for waste gases from the forming area and/or curing ovens\n(v)\nWaste gas incineration\nThe technique is generally applicable for the treatment of waste gases from curing ovens, in particular in the stone wool processes.\nThe application to combined waste gases (forming plus curing) is not economically viable because of the high volume, low concentration, low temperature of the waste gases\nTable 53\nBAT-AELs for air emissions from downstream processes in the mineral wool sector, when treated separately\nEmission levels expressed in kg/tonne of finished product are not affected by the thickness of the mineral wool mat produced nor by extreme concentration or dilution of the flue-gases. A conversion factor of 6,5 × 10–3 has been used.\nIf high density or high binder content mineral wools are produced, the emission levels associated with the techniques listed as BAT for the sector could be significantly higher than these BAT-AELs. If these types of products represent the majority of the production from a given installation, then consideration should be given to other techniques.\nParameter\nBAT-AEL\nmg/Nm3\nkg/tonne finished product\nForming area – Combined forming and curing emissions-Combined forming, curing and cooling emissions\nTotal particulate matter\n< 20 – 50\n—\nPhenol\n< 5 – 10\n—\nFormaldehyde\n< 2 – 5\n—\nAmmonia\n30 – 60\n—\nAmines\n< 3\n—\nTotal volatile organic compounds expressed as C\n10 – 30\n—\nCuring oven emissions\nTotal particulate matter\n< 5 – 30\n< 0,2\nPhenol\n< 2 – 5\n< 0,03\nFormaldehyde\n< 2 – 5\n< 0,03\nAmmonia\n< 20 – 60\n< 0,4\nAmines\n< 2\n< 0,01\nTotal volatile organic compounds expressed as C\n< 10\n< 0,065\nNOX, expressed as NO2\n< 100 – 200\n< 1",
