Product purity
increase at the expense of energy of the exhaust gas in the pressure swing
adsorption process
Abstract
It has been
shown that purity of the product gas
increases while ratio of gas pressure during the gas-vent step to gas pressure
during the adsorption step, decreases. As applied to a series of the adsorbers
operated in-parallel, this ratio is proposed to be reduced by means of the
adsorber vacuumization during the gas-vent step with the help of ejection by
using the exhaust gas flow, discharging from other adsorbers.
