The document discusses Nitech nitrogen rejection unit (NRU) technology for processing natural gas. It notes that the NRU uses cryogenic processing to economically remove nitrogen from gas streams without the complexity of traditional cryogenic methods. The NRU typically only includes an inlet compressor, heat exchanger, and cryogenic box, providing a small footprint and lower costs than other options. Over 24 NRU systems have been installed to process low-BTU gas, enhance oil recovery, and remove nitrogen, carbon dioxide, helium, and oxygen from treated gas streams. The document promotes the NRU technology and experience of the company for various gas processing applications.

Nitech™ Nitrogen Rejection (NRU) Technology
Enables producers to recover once by-passed reserves, regardless of nitrogen content. It
economically removes nitrogen from natural gas streams without the complexity and
inexibility typically associated with traditional cryogenic processes.
Typically only three major components;
The NRU generally only includes an inlet compressor, a heat exchanger and the cryogenic
box. The design will provide you a small footprint and the module equipment will provide a
lower investment cost.
No cryogenic rotating equipment required;
Upstream of the heat exchanger, the necessary compression is performed for the remaining
of the process. Therefore there are no cryogenic compressors or pumps required.
A less complex, more reliable and lower cost design;
No double column with external refrigerant lines or cryogenic pumps. Therefore, lower
investment, less maintainance costs and much lower power and compression requirements
than other (non-)cryogenic technologies.
High methane recovery in excess of 99%;
The Nitech NRU can easily recovery over +99% of the methane inlet. This will deliver you the
largest high quality natural gas stream and the lowest emissions from the nitrogen vent.
Variable nitrogen contents with only operator set point changes required;
Nitrogen content can easily range from 5% to 70% without any changes required. Moreover,
regardless of the nitrogen varation, the NRU can keep a constant nitrogen outlet (within the
sales gas pipeline) as low as 1%, depending on pipeline requirements.
Flexible in size and inlet content;
Available for ow rates of 30 to 2500+ million cubic meters per year. Also the design can
handle nitrogen contents between 5% to 90%. This range has a wide coverage and will
certainly assist you in creating high quality natural gas, which brings you the economic
results.
