FIELD: heating, drying.
SUBSTANCE: unit for liquid mercaptans adsorptive dehydration can be used in gas processing, oil refining, chemical and other industries, in particular, for dehydration or pre-dehydration of the natural odorant. The unit uses zeolites KA or NaA as adsorbent filling at least four vessels functioning as adsorber-desorber, wherein dehydration of the liquid mercaptans is performed in two adsorbers connected in series, the first adsorber ensures coarse dehydration of the mercaptans, ther second adsorber ensures fine dehydration of the mercaptans; the adsorbent regeneration is performed in the third adsorber by flow of hot stripping methane containing gas, and the adsorbent is cooled after regeneration by flow of cold methane containing gas in the forth adsorber.
EFFECT: improved dehydration efficiency.
