  "heading": "In order to prevent or reduce emissions of organic compounds to air and emissions to water of organic substances from the vacuum systems, BAT is to use one or a combination of the techniques given below.",
  "text": "Technique\nDescription\nApplicability\na.\nWater-free vacuum generation\nUse of dry-running pumps, e.g. positive displacement pumps\nApplicability to existing plants may be restricted by design and/or operational constraints\nb.\nUse of water ring vacuum pumps with recirculation of the ring water\nThe water used as the sealant liquid of the pump is recirculated to the pump casing via a closed loop with only small purges, so that waste water generation is minimised\nOnly applicable when technique a. cannot be applied.\nNot applicable for triethanolamine distillation\nc.\nReuse of aqueous streams from vacuum systems in the process\nReturn aqueous streams from water ring pumps or steam ejectors to the process for recovery of organic material and reuse of the water. The extent to which water can be reused in the process is restricted by the water demand of the process\nOnly applicable when technique a. cannot be applied\nd.\nCondensation of organic compounds (amines) upstream of vacuum systems\nSee Section 12.1\nGenerally applicable",
