Abstract:
Gas processing plants and methods are contemplated in CO 2  is effectively removed to very low levels from a feed gas to an NRU unit by adding a physical solvent unit that uses waste nitrogen produced by the NRU as stripping gas to produce an ultra-lean solvent, which is then used to treat the feed gas to the NRU unit. Most preferably, the physical solvent unit includes a flash unit and stripper column to produce the ultra-lean solvent.

Claim (Index 1):
A method of regenerating an ultra-lean solvent for deep CO 2  removal of a treated feed gas, comprising:\n using an ultra-lean physical solvent in an absorber to remove CO 2  from the treated feed gas to thereby form a CO 2 -loaded physical solvent and a CO 2 -depleted feed gas; removing in a nitrogen rejection unit N 2  from the CO 2 -depleted feed gas to thereby produce a N 2  waste stream and a pipeline gas; and regenerating the ultra-lean physical solvent from the CO 2 -loaded physical solvent in a process that includes flashing the CO 2 -loaded physical solvent and stripping the flashed CO 2 -loaded physical solvent using the N 2  waste stream as a stripping gas.
