US 2026/0131276 A1 · APPARATUS AND PROCESS FOR LOW TEMPERATURE REGENERATION OF ADSORBENT MATERIAL

Abstract

An apparatus and process for low temperature regeneration that can be utilized in adsorption systems can include feeding low temperature regeneration gas to at least one off-line adsorber for regeneration of the adsorbent material within the vessel of the off-line adsorber(s). The regeneration time period can be set to facilitate regeneration of the adsorbent material without a need for a high temperature regeneration to occur. Some embodiments can be configured so a post-cooling operation while the regeneration gas is fed to the adsorber(s) can be avoided to permit embodiments to more effectively utilize heating time.

A process for operation of an adsorption apparatus, comprising:

feeding a compressed gas to at least one first adsorber of an adsorption apparatus in an online state to remove one or more impurities from the compressed gas via adsorbent material of the at least one first adsorber for a pre-selected purification time period;
and
feeding a regeneration gas to at least one second adsorber of the adsorption apparatus in an offline state at a pre-selected regeneration temperature within a pre-selected regeneration low temperature range for a pre-selected regeneration time period to heat adsorbent material of the at least one second adsorber to the pre-selected regeneration temperature to regenerate the adsorbent material of the at least one second adsorber.

An adsorption apparatus, comprising:

a first adsorber adjustable between an online state in which a compressed gas is feedable into a vessel of the first adsorber to contact a bed of adsorbent material to remove one or more impurities from the compressed gas and an offline state in which a regeneration gas is feedable into the vessel of the first adsorber to contact the bed of adsorbent material of the first adsorber to desorb the one or more impurities from the bed of adsorbent material of the first adsorber to regenerate the bed of adsorbent material of the first adsorber;
and
a second adsorber adjustable between an online state in which the compressed gas is feedable into a vessel of the second adsorber to contact a bed of adsorbent material of the second adsorber to remove one or more impurities from the compressed gas and an offline state in which the regeneration gas is feedable into the vessel of the second adsorber to contact the bed of adsorbent material of the second adsorber to desorb the one or more impurities from the bed of adsorbent material of the second adsorber to regenerate the bed of adsorbent material of the second adsorber;
at least one regeneration gas heating device positioned upstream of the first adsorber and the second adsorber to heat the regeneration gas to a pre-selected regeneration temperature within a pre-selected regeneration low temperature range for a pre-selected regeneration time period.
