El Paso Natural Gas Company

The raw material at this plant is natural gas supplied by the El Paso Natural Gas Company from a nearby pumping station. In each process train, gas is compressed to 850 psig, dehydrated by an adsorption method to remove 100% of the water, then passed through a refrigeration unit to lower the temperature to -60°F. A separator removes liquids upstream of the turboexpander. 

A methane gas stream taken off the demethanizer process, and still at 350 psig, is compressed via byproduct energy from the turboexpanders and raised to 410 psig. The gas is then introduced into a 15,000 hp compressor and raised to 850 psig for delivery back to the El Paso Natural Gas Company. The 60 psig boost by each turboexpander represents a 15% reduction in required horsepower. This amounts to considerable energy saved and is yet another reason why the turboexpander is useful in a cryogenic process of this type. 

Econamine A process for removing acid gases from natural gas by selective absorption in diglycolamine (also called [2-(2-aminoethoxy) ethanol], and DGA). Developed by the Fluor Corporation, the El Paso Natural Gas Company, and the Jefferson Chemical Company and widely used. Later versions, developed by Fluor Daniel International, include the Fluor Daniel Econamine and the Econamine FG processes. More than 30 units were operating in 1996. See also Aromex. 

In helping to create a consensus set of guidelines, a number of individual and groups provided valuable assistance and review. These include Ted Krauthammer of Penn State, chairman of ACI committee 370 (Short Duration Dynamic and Vibratory Load Effects), Paul Mlakar of Jaycor, chairman of the ASCE Task Committee on Physical Security, and Quentin Baker of Wilfred Baker Engineering. Reviewers included Brad Otis of Shell Oil Company, Al Wusslcr of El Paso Natural Gas Company, and Eve Hinman of Failure Analysis Associates. 

It is intended to install on-site energy measurement at all of Southern California Gas Compare utility electric generating plants as well as its wholesale customers (approximately 30 locations). Currently, however, only four pilot installations are in and operating and these are at our own facilities. They are located at Blythe, Needles, and Newberry Springs, the points where we measure the gas we purchase from El Paso Natural Gas Company and Transwestem Pipeline Compaity, our major out-of-state suppliers. These locations are all in the Mojave Desert and it is believed that if the eqiripment will operate under these severe conditions, it will operate anyv/here. Temperatures at these locations may vary on a daily basis by as much...
