  "text": "Technique\nDescription\nApplicability\nProcess-integrated techniques\na.\nStaged CO2 desorption\nThe technique consists of conducting the depressurisation necessary to liberate the carbon dioxide from the absorption medium in two steps rather than one. This allows an initial hydrocarbon-rich stream to be isolated for potential recirculation, leaving a relatively clean carbon dioxide stream for further treatment.\nOnly applicable to new plants or major plant upgrades\nAbatement techniques\nb.\nCatalytic oxidiser\nSee Section 12.1\nGenerally applicable\nc.\nThermal oxidiser\nSee Section 12.1\nGenerally applicable\nTable 6.1\nBAT-AEL for emissions of organic compounds to air from the desorption of CO2 from the scrubbing medium used in the EO plant\nThe BAT-AEL is expressed as an average of values obtained during 1 year.\nIn the case of significant methane content in the emission, methane monitored according to EN ISO 25140 or EN ISO 25139 is subtracted from the result.\nEO produced is defined as the sum of EO produced for sale and as an intermediate.\nParameter\nBAT-AEL\nTVOC\n1–10 g/t of EO produced\nThe associated monitoring is in BAT 2.",
