A Horton sphere (sometimes spelled Hortonsphere), also referred to as a spherical tank or simply sphere, is a spherical pressure vessel, which is used for industrial-scale storage of liquefied gases. Example of materials that can be stored in Horton spheres are liquefied petroleum gas (LPG), liquefied natural gas (LNG), and anhydrous ammonia. [1]
Ethane (US: / ˈ ɛ θ eɪ n / ETH-ayn, UK: / ˈ iː θ eɪ n / EE-thayn) is a naturally occurring organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by ...
These comprise a de-ethaniser, a de-propaniser and a de-butaniser, the constituent components and products from the plant are: ethane (C 2 H 6), propane (C 3 H 8), butane (C 4 H 10) and pentane (C 5 H 12) or natural gasoline. [4] [6] The ethane is piped to an adjacent ethylene (ethene) cracker plant operated by ExxonMobil for processing and ...
Synthetic aperture radar image mosaic of Titan's north polar region. Vid Flumina is a river system (termed Flumen) of liquid methane and ethane on Saturn's moon Titan.It is more than 400 km (249 mi) long and flows into Titan's second largest hydrocarbon sea, Ligeia Mare. [1]

The name plastic crystal refers to the mechanical softness of such phases: they resemble waxes and are easily deformed. If the internal degree of freedom is molecular rotation, the name rotor phase or rotatory phase is also used. Typical examples are the modifications Methane I and Ethane I.
The possibility remained that liquid ethane and methane might be found on Titan's polar regions, where they were expected to be abundant and stable. [7] In Titan's south polar region, an enigmatic dark feature named Ontario Lacus was the first suspected lake identified, possibly created by clouds that are observed to cluster in the area. [8]
