Processes for sorbent regeneration

A method for operating regeneration cycles of a sorbent housing array (100), wherein the sorbent housing array comprises two or more sorbent housing apparatuses (102a, 102b, . . . ), each housing apparatus comprising two or more sorbent housing modules (104a, 104b, . . . ), each housing module configured to hold a sorbent to capture a gas from a gas mixture, wherein the sorbent housing modules (104a, 104b, . . . ) of each respective sorbent housing apparatus (102a) are coupled to one another for sequential regeneration by a regenerating unit (106) in a regeneration cycle (270), the method comprises:

• a. starting a regeneration cycle for a first group (220a or 320a) of sorbent housing apparatuses (102a, 102b, . . . ) at time TS1, wherein the first group comprises at least one sorbent housing apparatus (102a),
• b. starting a regeneration cycle for a second group (220b or 320b) of sorbent housing apparatuses at time TS2, wherein the second group (220b or 320b) comprises at least one sorbent housing apparatus (102a)
• c. starting a regeneration cycle for applicable remaining groups (220c, . . . or 320c, . . . ) of sorbent housing apparatuses (102a, 102b, . . . ) in the array (100), wherein each group has its own respective start time (TSi) at which the respective regeneration cycle is started;
• wherein the start time, TSi, for each of the groups in the array is not the same as one another;
• d. sequentially performing regeneration of the sorbent in the respective sorbent housing modules (104a, 104b, . . . ) of the sorbent housing apparatus(es) (102a) in each group (220a, 222b, . . . ) to complete the respective regeneration cycle;
• wherein performing the regenerating cycle generates a desorbed stream (180) from each respective sorbent housing apparatus (102a, 102b, . . . );
• and
• e. providing the desorbed streams from all sorbent housing apparatuses of the array to a processing equipment (108).
