摘要： In a process for the separation of a flow containing at least 97% mol of carbon monoxide containing at least one lighter compound and at least one heavier compound, the flow is separated in a column and a column, one of the columns being a denitrogenation column and the other a column for purification in argon, in order to form a flow very rich in carbon monoxide.

摘要： A gas stream is purified by a TSA adsorption scheme including at least two adsorbers following, in an offset manner, a cycle including an adsorption phase, and a subsequently, a regeneration phase. The regeneration phase includes a depressurization step, a pre-regeneration step and a regeneration step. A gas circulator is used to circulate the gas within the adsorber in the pre-regeneration step in a closed loop while the circulating gas is heated with a heater.

摘要： A facility and method for membrane permeation treatment of a feed gas flow containing at least methane and carbon dioxide that includes a compressor, a pressure measurement device, at least one valve, and first, second, third, and fourth membrane separation units for separation of CO2 from CH4 to permeates enriched in CO2 and retentates enriched in CH4, respectively. A temperature of the first retentate is adjusted at an inlet of the second membrane separation unit with at least one heat exchanger as a function of the measured CH4 concentration in such a way so as to reduce the determined difference.

摘要： Disclosed is a method for purifying a main gas, in particular helium, from a source gas stream comprising the main gas, a main impurity, in particular nitrogen, and optionally another, secondary impurity, in particular oxygen, the method comprising a step of partial condensation of the gas stream in order to extract therefrom impurities in liquid form, in particular the main impurity, and to produce a gas stream enriched with main gas, characterized in that the method comprises, before the partial condensation step, a step of injecting into the gas stream a compound in which the main impurity of the gas to be treated is soluble and having a saturation vapor pressure lower than the saturation vapor pressure of the main impurity.
