In viscose fibre factories, where a chemical regeneration takes place during the spinning process and sodium sulphate and water develop from soda lye and sulphuric acid, the so-called spinbath is used and diluted. In former times this spinbath was used once and then drained as waster water. This caused enormous environment
      Problems and high operating costs, and made it absolutely necessary to regenerate the spinbath and lead it back into the process, respectively recover a saleable production from a part of the spinbath.
In a regeneration plant the following process steps are necessary:
      ¡ª¡ªdegassing (if necessary )
      ¡ª¡ªevaporation
      ¡ª¡ªcrystallization of the glauber¡¯s salt
      ¡ª¡ªregeneration of the glauber¡¯s salt to sodium sulphate (melting crystallization)
      EBNER is also specialized in the planning and construction of complete spinbath regeneration plants. Each plant section is designed according to the prevailing conditions. As the planning and the fabrication are in one hand, existing plant components can be integrated. EBNER not only constructs new plants, but is also engaged in the conversion and extension of existing plants.
      EBNER can design and supply the apparatus and process with the newest idea for customer producing Viscose Model and Lyocell. Advanced process of regeneration of NMMO solvent has been applied widely in the world.
