Recent experimental work with currently available adsorbents indicates
that operating the adsorption section at lower temperatures improves the
para-xylene productivity. As a result, an aromatics complex and heat
recovery network for a low temperature adsorptive
separation-isomerization loop is disclosed resulting in adsorbents
savings in combination with higher capacity thereby enabling smaller
adsorbents chambers, a smaller total heat exchanger area and a lower heat
exchanger shell count.
