Abstract: LNG vapor from an LNG storage vessel is absorbed using C3 and heavier components provided by a fractionator that receives a mixture of LNG vapors and the C3 and heavier components as fractionator feed. In such configurations, refrigeration content of the LNG liquid from the LNG storage vessel is advantageously used to condense the LNG vapor after separation. Where desired, a portion of the LNG liquid may also be used as fractionator feed to produce LPG as a bottom product.

Abstract: LNG is pumped to supercritical pressure and vaporized, preferably in an offshore location to thereby form a natural gas stream with an intermediate temperature. A first portion of that stream is then processed in an onshore location to remove at least some non-methane components to thereby form a lean LNG, which is then combined with a second portion of that stream to form a sales gas having desired chemical composition. The intermediate temperature and the split ratio of the gas stream in first and second portion are a function of the concentration of the non-methane components in the LNG.
Abstract translation: LNG被泵送到超临界压力并蒸发，优选在海上位置，从而形成具有中间温度的天然气流。 然后将该物流的第一部分在陆上处理以除去至少一些非甲烷组分，从而形成贫LNG，然后将其与该流的第二部分组合以形成具有所需化学成分的销售气体。 第一和第二部分中的气流的中间温度和分流比是LNG中非甲烷组分的浓度的函数。

Abstract: Contemplated NGL plants include a feed gas bypass circuit through which a portion of the feed gas is provided downstream to a vapor portion of the feed gas to thereby increase turbo expander inlet temperature and demethanizer temperature. Contemplated configurations are especially advantageous for feed gases with relatively high carbon dioxide content as they entirely avoid carbon dioxide freezing in the demethanizer, provide additional power production by the turboexpander, and recover C2+ components to levels of at least 80% while achieving a low carbon dioxide content in the NGL product.

Abstract: Contemplated plants and methods for NGL recovery from feed gases having a carbon dioxide content equal or greater than about 2% employ temperature control configurations that allow high-level and flexible recovery of ethane and heavier components while avoiding freezing of the carbon dioxide in the process. Where the feed gas has a significant fraction of C3+ components and moderate carbon dioxide content, a single column configuration with an intermediate reflux condenser may be used, while two-column configurations may be used for feed gases with high carbon dioxide content and relatively low C3+ component concentration.

Abstract: Liquefied natural gas (LNG) is heated in a plant by a heat source and the heated LNG is expanded to produce work. In particularly preferred plants, the heat source is a combined cycle power plant, and the work is used to recompress pipeline gas produced from the heated LNG. Additionally, the refrigeration content in LNG may be utilized to increase the power generation capacity and efficiency of a combined cycle power plant.
