Abstract

Inventia se refera la un procedeu si o instalatie de uscare a amoniacului utilizat la tratamentul termochimic de nitrurare a pieselor si sculelor din oteluri inoxidabile si înalt aliate, în vederea realizarii conditiilor de obtinere a straturilor cu grosime uniforma, lipsite de oxizi si cu caracteristici superioare, prin utilizarea unei instalatii formata din coloane cu adsorbanti solizi si sistem de regenerare termica. Functionarea coloanelor are loc alternativ, una fiind în faza de uscare, alta în faza de regenerare (încalzire-racire). Prin dizolvarea în apa a gazelor utilizate la regenerarea coloanelor se poate obtine apa amoniacala, utilizata în scopuri industriale.
