Enhancing the Benefits and Overcoming the Limitations of LNG and CNG

 

Natural Gas – Storage  •  Transport  •  Supply

Optimal conditions for storage and bulk transport of natural gas were defined in the 1960’s by H. C. Secord. When the cost of containment is combined with the cargo density and cost (and/or energy) required for compression and refrigeration of the natural gas, true optima can be defined for containment in carbon and stainless steel tanks. The optimal conditions were explored and confirmed through the full scale test program of R. J. Broeker and the Columbia Gas System Service Corp. through the early 1970’s.

A massive R&D program by ExxonMobil in the 1990’s and 2000’s re-confirmed the advantages of liquefying natural gas at temperatures well above traditional LNG by applying modest containment pressure. A “Pressurized LNG (PLNG)” facility is much simpler and less than half the size, requiring only about half as much energy as conventional LNG while producing a fluid nearly as dense (ref. Bowen et al, GasTech 2005). The reduced, size, cost and complexity of a PLNG plant makes it possible to build a “warm LNG” plant on a big offshore barge.

Now, ezNG Solutions LLC offers a tank concept that provides containment for traditional LNG or “warm LNG” as well as patented gas handling technology for injecting natural gas fluids into and extracting them from containment. The ezNG® cells can be used individually or in assemblies that efficiently fill storage volume spaces (e.g., in storage vaults or transportable intermodal containers). The storage efficiency for ezNG® is an order of magnitude higher than that of CNG.
