  "number": "BAT 35",
  "heading": "In order to reduce the consumption of treatment chemicals and the consumption of energy and to reduce emissions of treatment chemicals, BAT is to optimise the wood charge of the vessel and to avoid trapping of treatment chemicals by using a combination of the techniques given below.",
  "text": "Technique\nDescription\nApplicability\n(a)\nSeparation of wood in packs by spacers\nSpacers are placed at regular intervals in the packs to facilitate the flow of treatment chemicals through the pack and the draining after treatment.\nGenerally applicable.\n(b)\nSloping of wood packs in traditional horizontal treatment vessels\nWood packs are inclined in the treatment vessel to facilitate the flow of treatment chemicals and the draining after treatment.\nGenerally applicable.\n(c)\nUse of tilting pressure treatment vessels\nThe whole treatment vessel is inclined after treatment so that excess treatment chemicals drain easily and can be recovered from the bottom of the vessel.\nOnly applicable to new plants or major plant upgrades.\n(d)\nOptimised positioning of shaped wood pieces\nShaped wood pieces are positioned so as to prevent trapping of treatment chemicals.\nGenerally applicable.\n(e)\nSecuring wood packs\nThe wood packs are secured inside the treatment vessel in order to limit the movement of wood pieces which could change the structure of the pack and reduce the impregnation efficiency.\nGenerally applicable.\n(f)\nMaximisation of the wood load\nThe wood load in the treatment vessel is maximised to ensure the best ratio between the wood to be treated and the treatment chemicals.\nGenerally applicable.",
