Abstract:
A method for providing upgraded biogas includes feeding a stream of biogas into a biogas upgrading system in order to remove carbon dioxide from the stream of biogas. The biogas upgrading system, which may be based on absorption, adsorption, membrane permeation, and/or cryogenics, provides a stream of upgraded biogas and a tail gas stream. The tail gas stream, which may be CO 2 -rich, is enriched with natural gas so that it is combustible in medium-BTU equipment. The upgraded biogas is used for transportation use and/or the generation of fuel credits. Accordingly, both the tail gas and the upgraded biogas are used effectively and at lower cost.

Claim (Index 60):
The method according to  claim 50 , wherein the biogas upgrading system comprises:\n a separating unit for removing carbon dioxide from biogas to provide upgraded biogas and tail gas, said separating unit including a first inlet configured to receive the biogas, a second inlet configured to receive natural gas; a first outlet configured to provide the upgraded biogas, and a second outlet configured to provide the tail gas, said separating unit comprising the membrane having a feed side and a permeate side, wherein passing biogas across the feed side of the membrane comprises passing biogas received at the first inlet across said feed side of the membrane such that upgraded biogas is provided at the first outlet, and wherein passing natural gas across the permeate side of the membrane as a sweep stream comprises passing natural gas received at the second inlet across the permeate side of the membrane such that the permeate comprising carbon dioxide is conveyed with the natural gas to the second outlet.
