1) Nitrogen Rejection with Integrated High NGL Extraction

Estimates place as much as 25% of the natural gas in the United States out of specification with regard to nitrogen content. Typically, a processor can expect the pipelines to require less than 3.0 mole percent nitrogen in their natural gas stream. With a decline in conventional natural gas sources and with a recent increase in political desire to better utilize clean burning natural gas, there is a need for these unconventional sources of natural gas. For the United States to also become energy independent, natural gas will have to take a larger role in our daily lives in the future. There is no doubt that shale gas is propping up the decline curve with respect to conventional gas, but low-BTU gas is another economically viable option. With the recent increase in oil prices, there is now a greater opportunity for nitrogen rejection with integrated NGL extraction, and specifically high NGL recovery.

2) BCCK’s Nitech™ Nitrogen Rejection Process Provides Solution to Meeting Tighter US Pipeline Restrictions

As the demand for natural gas continues to escalate in the US and around the globe, unconventional gas sources are receiving more attention as viable energy options. Global environmental pressure is fueling demand for natural gas as a clean-burning, environmentally friendly power generation alternative to aging coal–fired power plants. Natural gas facilities have relatively low emissions of sulfur dioxide and particulate matter and far lower levels of“greenhouse” gas emissions, an advantage which politically supports a global shift from oil and coal to natural gas.

3) Nitrogen Separation Technologies: Best Served Hot or Cold?

Today’s market of sustainable high gas prices and dwindling reserves has caused producers to consider non-traditional sources of revenue generation. Once considered trash gas or a waste stream, high nitrogen reserves are now being reexamined as economically viable.In the past, smaller gas wells that tested high in nitrogen were simply shut in because the cost of producing such gas was not feasible. Today, however, advancements in technology, in both cryogenic separation and pressure swing adsorption and absorption have made nitrogen rejection a profitable reality, even for smaller gas streams.

4) Nitech™ Nitrogen Rejection Technology: Efficiency Without the Complexity Typically Associated with Nitrogen Rejection

In 1994, a new technology for separating nitrogen from natural gas was introduced with a full-scale processing plant located near Mist, Oregon. Several years of research and development by BCCK Engineering, Inc. preceded the installation of the facility. Prior to the installation of the Mist unit, BCCK engineers spent a significant amount of time optimizing the nitrogen rejection unit (NRU) simulation to ensure that hydrocarbon recovery was as efficient as possible, while providing a design that was economical and uncomplicated. To ensure a less complicated design, BCCK scheduled interviews with operators of conventional cryogenic NRUs to survey operational concerns. The results of these discussions prompted BCCK to develop and patent a nitrogen rejection technology, Nitech™, which requires no cryogenic rotating equipment, as these elements are consistently responsible for facility downtime and excessive operating expense.

5) PRESENTATION (midcontinent gpa, Oklahoma city, OK -- april 2009): Nitech™ - Proven technology for the gas industry

BCCK Engineering, Inc., a privately owned, Midland, Texas based firm, specializes in engineering and technology services to clients on a worldwide basis. BCCK has been in business for over 28 years and we are the licensor of the patented Nitech™ nitrogen rejection process, which the EPA recognized for clean and efficient nitrogen rejection from high nitrogen gas streams. BCCK has been the most active NRU supplier in the United States for the past 10 years. We maintain a complete staff of engineers, designers, technical support and financial specialists. We provide full fabrication facilities via the NG Resources Corporation.

6) Nitech™ Nitrogen Rejection with Integrated Helium Extraction

Formed through the radioactive decay of heavy metals uranium and thorium, the vast majority of the earth’s supply of helium permeates through the earth’s surface and, being lighter than air, eventually dissipates into outer space. As it is not currently feasible or economic to process the helium existing in the atmosphere, the majority of the world’s helium supply is processed from non-porous cavities which also contain high nitrogen natural gas. Should conditions merit, for gas processors fortunate enough to find helium reserves comingled in their low-BTU natural gas plays, the helium stream can be of significant monetary value.
