Natural gas plays a growing role in the energy mix by displacing coal due to its relative economic and/or environmental advantages A process of natural liquid (NGL) recovery utilizing internally generated achieve efficiency was designed. The utilizes heat from compressor end turbo-expander provide required maintain appropriate operating conditions at intermediate and bottom sections demethanize...

The escalating cost for next generation lithography ~NGL! tools is driven in part by the need for complex sources and optics. The cost for a single NGL tool could exceed $50M in the next few years, a prohibitive number for many companies. As a result, several researchers are looking at low cost alternative methods for printing sub-100 nm features. In the mid-1990’s, several research groups star...

Abstract Numerical weather models (NWMs) are important data sources for space geodetic techniques. Additionally, the Global Navigation Satellite System (GNSS) provides many observations to continuously improve and enhance NWM. Existing comparative analysis experiments on NWM tropospheric GNSS delays suffer from being conducted in highly specific regions with limited spatial coverage; furthermor...

Abstract Recent technological improvements have driven the rapid increase in natural gas production from unconventional reservoirs. The heaviest hydrocarbon fraction of this fossil fuel, so-called liquids (NGL), greater economic interest justifying attention on its separation process raw gas. Various schemes been developed and studied for NGL recovery, including conventional, cold residue recyc...

The development of floating liquefied natural gas (FLNG) plants has resulted in a focus on reducing the weight and size of the topside processing facilities for these units. The conventional fractionation of natural gas liquids (NGL) in LNG plants implies a direct sequence of three or more conventional distillation columns requiring different levels of refrigeration. The results of a feasibilit...
