Adsorbent Allocation within the Molex Process

The adsorbent used in the Sorbex process is partitioned into discrete beds within the Sorbex chambers. These beds are then allocated among four main Sorbex zones. Table 8.2 lists these zones and their corresponding function. 

I Adsorption Adsorption of normal paraffins from the feed with simultaneously displacement of desorbent normals from the adsorhenf s selective volume 

II Purification Enrichment of feed normals and displacement of non-normals 

III Desorption Desorption of the normal paraffins from the adsorbent selective volume by Desorbent normals 

IV Buffer Maintains reject or Raffinate non-normals hydrocarbons from entering Zone 111 and contaminating the Extract product (normal paraffins)
