Abstract:
1. An apparatus for separating butene-1 from a mixture gas of C4 olefins/paraffins by separating the C4 olefins from a mixture gas of C4 olefins/paraffins and distilling the separated C4 olefins by carrying out repeated sequential adsorbing, rinsing and desorbing in such a way of performing displacement desorption using desorbents, in adsorption towers loaded with adsorbents which selectively adsorb olefins and a distillation tower for the separation of olefins/desorbents, a distillation tower for the separation of paraffins/desorbents, and a distillation tower for the separation of butene-1 that separate the C4 olefins recovered from the adsorption towers by using desorbents, wherein the adsorption tower is configured to include: an adsorption tower (AD- an adsorption tower (AD- an adsorption tower (AD- wherein the conduit ( wherein the distillation tower for the separation of paraffins/desorbents is the distillation tower (D
