    • Bulk storage of natural gas or methane is facilitated by absorbing and storing the gas in a liquefied medium through the interaction of moderate pressure, low temperature and a solvent medium. Systems and processes are provided that facilitate the absorption of natural gas or methane into a liquid or liquid vapor medium for storage and transport, and back into a gas for delivery to market. In a preferred embodiment, the absorptive properties of ethane, propane and butane under moderate conditions of temperature and pressure (associated with a novel mixing process) are utilized to store natural gas or methane at more efficient levels of compressed volume ratio than are attainable with natural gas alone under similar holding conditions. The preferred mixing process efficiently combines natural gas or methane with a solvent medium such as liquid ethane, propane, butane, or other suitable fluid, to form a concentrated liquid or liquid vapor mixture suited for storage and transport. The solvent medium is preferably recycled in the conveyance vessel on unloading of the natural gas.
    • 通过中等压力,低温和溶剂介质的相互作用,将气体吸收并储存在液化介质中,便于天然气或甲烷的大量储存。 提供了系统和方法,其促进将天然气或甲烷吸收到用于储存和运输的液体或液体蒸气介质中,并且返回到用于输送到市场的气体中。 在优选的实施方案中,乙烯,丙烷和丁烷在适度的温度和压力条件下(与新的混合过程相关联)的吸收性能被用于以比天然气可获得的更有效的压缩体积比水平储存天然气或甲烷 天然气单独在相似的保持条件下。 优选的混合过程有效地将天然气或甲烷与溶剂介质如液体乙烷,丙烷,丁烷或其它合适的流体相结合,形成适合于储存和运输的浓缩液体或液体蒸汽混合物。 溶剂介质优选在卸载天然气时在输送容器中再循环。
