METHOD AND SYSTEM FOR SEPARATING A FEED FLOW
A method and a system for separating a feed flow which contains at least hydrogen and a hydrocarbon with three or four carbon atoms per molecule, in particular propane, propylene, propadiene, butane, 1-butene, 2-butene, and/or 1,3-butadiene. The condensed feed flow is cooled over multiple cooling st...

| description | A method and a system for separating a feed flow which contains at least hydrogen and a hydrocarbon with three or four carbon atoms per molecule, in particular propane, propylene, propadiene, butane, 1-butene, 2-butene, and/or 1,3-butadiene. The condensed feed flow is cooled over multiple cooling steps in at least two heat exchangers and is then separated into a condensate and a residual gas flow after each cooling step. The at least two heat exchangers are operated at least two different temperature levels, wherein a hot heat exchanger is operated at an average temperature level, and a cold heat exchanger is operated at a lower temperature level. An internal refrigerant which is made of a part of one of the condensate flows and a part of one of the residual gas flows, is used to dispense a part of the heat from the cold heat exchanger. |
