<p>Separation of gas stream (n-product) containing predominantly low-boiling hydrocarbon from a gas stream (raw gas) containing high-boiling hydrocarbon and condensation of the n-product by at least a single stage, comprises cooling and subsequent phase separation of at least a gas stream (12, 25) as main stream from a separating column (T1, T2), in which a gas stream (7, 19) is led for rectification and at whose head at least a part of the liquid phase (14, 28) obtained by phase separation (D2, D4) is fed back. Separation of gas stream (n-product) containing predominantly low-boiling hydrocarbon from a gas stream (raw gas) containing high-boiling hydrocarbon and condensation of the n-product by at least a single stage, where before the condensation and/or at least after one of the condensation step, a material separation takes place during which a liquid- and a gaseous- phase are obtained from a gas stream by cooling and subsequent phase separation, comprises cooling and subsequent phase separation of at least a gas stream (12, 25) as main stream from a separating column (T1, T2), in which a gas stream (7, 19) is led for rectification and at whose head at least a part of the liquid phase (14, 28) obtained by phase separation (D2, D4) is fed back. An independent claim is included for a device for separating the gas stream (n-product) from a gas stream (raw gas), comprising at least a compressor exhibiting a compression section, an arrangement for material separation and a gas-liquid separator.</p> |
