1. Sending 97% Nitrogen and 3% methane from Nitrogen rejection stream to NH3 plant.
2.Using thermal swing adsorber instead of a pressure swing adsorber.
To prevent the loss of feed gas in the bed during depressurization and also,the short time cycle in PSA can cause rapid re-pressurization that will lead to transient variation in the feed and product flow which will affect the operation of the plant
3. Using only one turboexpander for Hydrocarbon recovery.
