  "heading": "In order to reduce odour emissions and total reduced sulphur emissions due to strong and weak odorous gases, BAT is to prevent diffuse emissions by capturing all process-based sulphur containing off-gases, including all vents with sulphur-containing emissions, by applying all of the techniques given below.",
  "text": "The SOx emission levels of the lime kiln increase significantly when strong non-condensable gases (NCG) are fed to the kiln and no alkaline scrubber is used.\nApplicable for the treatment of weak odorous gases.\nApplicable for the treatment of strong odorous gases.\nTechnique\nDescription\na\nCollection systems for strong and weak odorous gases, comprising the following features:\ncovers, suction hoods, ducts, and extraction system with sufficient capacity;\ncontinuous leak detection system;\nsafety measures and equipment.\nb\nIncineration of strong and weak non-condensable gases\nIncineration can be carried out using:\nrecovery boiler\nlime kiln\ndedicated TRS burner equipped with wet scrubbers for SOx removal; or\npower boiler\nTo ensure the constant availability of incineration for odorous strong gases, back-up systems are installed. Lime kilns can serve as back-up for recovery boilers; further back-up equipment are flares and package boiler\nc\nRecording unavailability of the incineration system and any resulting emissions",
