Gas Absorber :
For this application a re-circulatory system incorporating a holding
vessel is the best solution , where the
proportion of feed gas can be reduced
to zero . The tank is pre-charged with a
calculated mass of absorbent , which is
circulated through the column. The gas
is introduced at a point between the two
heat exchangers , and rises through the
packing against the failing stream of
absorbent.The upper exchanger removes
the heat of solution , and the lower one
cools the product.
