Membrane Systems for Nitrogen Rejection By Kaaeid A. Lokhandwala, Andre Da Costa, Marc Jacobs and ... CH 4 ~ 200 Units O 2 /N 2 ~ 5,000 Units CO 2 /CH 4 ~ 200 Units Vapor/Gas Separation Systems VOC/Air Hydrocarbon/N 2. Cryogenic nitrogen rejection units (NRUs) play a critical role in gas processing operations. The primary goal of NRU operation is to maximize the amount of nitrogen that is removed from the residue sales gas stream. Phoenix Equipment Corporation has this used Nitrogen Rejection Unit (NRU) for sale immediately available. Nitrogen Rejection Units are installed in gas processing facilities to remove nitrogen from the residue sales gas so that this product stream complies with transmission pipeline specifications for nitrogen concentration. Most pipeline standards require that natural gas contain less than 4% nitrogen. Installed Cost $ 35,000 $ 35,000 $ 35,000 Operating Cost $ 15,000 $ 15,000 $ 15,000 Payback Period (months) 1.1 0.7 0.5. Nitrogen Rejection Unit This system offers a solution for the selective absorption of either Methane (released at low pressure) or Nitrogen, depending on needs, capturing Methane or rejecting Nitrogen (down to 3~4% output) depending on gas grid network standards. There is a great opportunity for nitrogen rejection with integrated NGL extraction, and specifically high NGL recovery. Nitrogen Rejection Units (NRUs) Tailored process technologies complemented by modular builds to meet all performance, efficiency and cost targets. Demand for natural gas is growing. Usually, nitrogen is not injected into these reserves to enhance recovery, so the rejected nitrogen has little or no value as a product stream. According to the Gas Research Institute, 17% of US gas reserves have high nitrogen. • World’s largest nitrogen rejection plant, optimised to minimise lifecycle costs and hydrocarbon emissions. Nitrogen Removal Units (NRU) can be expensive to build and difficult to operate. The challenges facing the gas industry are highlighted by the Gas Technology Institute (GTI, USA) in their estimates that 11% of current daily gas production and 16% of all known gas reserves in the USA contain some nitrogen. For this reason, the product nitrogen pressure at the outlet of the process is not important. Plus, the patented NiTech ® NRU delivers the efficiency of cryogenic processes with a much simpler, more reliable design. Phoenix Equipment is a global buyer and seller of used Nitrogen Rejection Unit and other natural gas process plants. NiTech ® Nitrogen Rejection Process. The NiTech ® process is an economical, effective and highly efficient way to remove high concentrations of nitrogen from as little as 5 MMSCFD. ... • Processing Costs about 0.25 to 0.5 $/MCF are very favorable • … concentrations following initial nitrogen breakthrough due to injection into the Cantarell oil field. E.ON UK - Gas processing plant with nitrogen rejection Installation of nitrogen rejection unit for a 200 In addition to helping meet pipeline reid vapor pressure (RVP) specifications and reducing emissions, removal of inert nitrogen from the raw stream reduces transport volume and increases the calorific (i.e., heating) value of natural gas. It is viewed as an increasingly important stepping stone on the journey towards a low-carbon economy. Nitrogen Rejection Units remove nitrogen from natural gas to prepare it for transport through pipelines. Removing nitrogen to increase thermal efficiency.

As nitrogen rejection unit (NRU) technology advanced, the obvious next step was to integrate NGL extraction with the cryogenic NRU process. It works equally well with inlet gas flows at 250 MMSCFD or greater.
