Biogas / RNG

Nitrogen rejection

checkmark

Landfill gas (LFG) often contains nitrogen. RNG pipelines have maximum nitrogen specifications which can be met using NORIT® RB3 in the Nitrogen Rejection Unit's (NRU) pressure swing adsorption (PSA) process.

checkmark

With the shift to RNG, the removal of nitrogen is important to biogas upgrading systems and maximizing the Btu value of the gas.

PSA Systems using NORIT activated carbon are one of the most effective and economical means for separating nitrogen from methane to upgrade biogas to RNG.

NORIT RB3 and RB4 activated carbon has been optimized for robust and highly efficient PSA nitrogen separation systems.
