**For stable operation replacement of adsorbent is required after every 4 years of
operation. However due to inappropriate use or unexpected inlet/operating conditions
adsorbent can be damaged sooner and in this case replacement is required sooner.
It is necessary to wear respiratory protective equipment when working with the
adsorbent. Adsorbent is a crumbling material that is producing fine dust which can
cause respiratory complications if inhaled in sufficient quantities.
