1) 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.

2) 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.

3) 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.
