Abstract: A process for separating the components of a gas mixture comprising methane, nitrogen, and at least one hydrocarbon having at least two carbon atoms, or a mixture of these hydrocarbons, including the following steps: a) demonization of the gas mixture with at least one demethenization column; b) extraction of a liquid comprising at least 85 mol % of the hydrocarbons having at least two carbon atoms, partial condensation of a gas mixture in order to obtain a liquid, at least a portion of which is treated in order to be extracted as denitrogenated natural gas product and a second gas; d) introduction of the second gas and/or the gas mixture into a nitrogen removal column, obtained from which are a gas and a liquid, e) treatment of the gas in a nitrogen removal system in order to produce a gas stream comprising 5 mol % at most of nitrogen.

Abstract: An animal flotation device is provided. The animal flotation device is a non-inflatable, semi-submersible flotation apparatus for a dog to stably sit, lay and move about while partially submerged in a body of water of any depth. The animal flotation device may have a peripheral portion defining an interior portion. The interior portion provides a generally rigid area adapted to become semi-submersed within the body of water when supporting the dog, whereby the peripheral portion provides buoyancy and stability to the semi-submersed interior portion so that the dog may move around and feel safe while floating atop the body of water.
