Abstract
This invention provides a method to smooth out the concentration peak generated from the regeneration stream of a cyclic adsorption process such as PTSA or TSA process. A fixed-bed adsorber (called a capacitor) to process the spent regeneration gas from a TPSA or TSA unit to maintain a constant composition of the spent regeneration gas to the downstream unit. The adsorber operates in a once-through non-cyclic manner, very similar to the conventional fixed bed reactor or adsorber. The spent regeneration gas stream coming out of the adsorber will have a more uniform COcomposition than without the capacitor.
