Method for operating an adsorption apparatus with cooling steps
The patent US12064723B2 outlines a method for operating an adsorption apparatus designed to efficiently adsorb target components from a gas stream using physical adsorbents. The apparatus consists of multiple adsorption beds that can alternate between two primary functions: one set of beds is used for the adsorption process, while another bed undergoes a regeneration process to remove the adsorbed components. The regeneration involves a desorption step where the adsorbent is heated to release the target component, followed by a cooling step that uses a cooling gas to lower the temperature of the adsorbent. This cooling continues until a predetermined outlet temperature is achieved, after which a standby phase is initiated, maintaining the cooled state with the gas to be treated.
Further details in the claims specify that during the desorption step, a regeneration gas is supplied to heat the adsorbent, and the cooling step involves a separate gas for cooling. The apparatus is designed with two gas lines: one for the gas to be treated during adsorption and another for the standby gas during the cooling phase. Notably, the standby gas is drawn from the gas to be treated, allowing for efficient resource use. Additionally, the flow rate of the standby gas is intentionally set lower than that of the gas used in the adsorption step, optimizing the operational efficiency of the adsorption apparatus. This method aims to enhance the performance and sustainability of gas treatment processes by effectively managing the adsorption and regeneration cycles.
