Products for Nitrogen Rejection Units (NRUs)

NitroRyd 2 – molecular sieve
Specialized molecular sieve that can selectively reject nitrogen from natural gas streams.
NitroRyd C – activated carbon
A unique adsorbent that can selectively separate nitrogen from natural gas.

Overview of Nitrogen Rejection Units

Nitrogen (N2) is commonly found in natural gas streams. Natural occurrences of nitrogen are typically low, but higher compositions can be caused by the injection of nitrogen into a gas pocket to increase the pressure inside and enhance drilling processes. For natural gas to maintain value and working ability, the composition of nitrogen should be below one percent and any excess nitrogen will need to be removed. Removing nitrogen from natural gas streams will also reduce the overall product stream volume during transportation, creating cost savings. Nitrogen Rejection Units (NRUs) are used to remove nitrogen from natural gas streams. Some NRU designs utilize molecular sieve under Pressure Swing Adsorption technology to selectively remove nitrogen to under one percent.
