Abstract
Описываются способ и установка для компактной перерабатывающей установки извлечения компонентов С(или С) и более тяжелых углеводородных компонентов из потока газообразных углеводородов. Газовый поток охлаждается и разделяется на первый и второй потоки. Первый поток дополнительно охлаждается, расширяется при более низком давлении, а затем подается в качестве сырья в зону между первым и вторым устройствами абсорбции. Второй поток расширяется при более низком давлении и подается в качестве сырья в нижнюю часть второго устройства абсорбции. Поток отгонного пара из устройства абсорбции нагревается, сжимается до более высокого давления и разделяется на летучую фракцию остаточного газа и на сжатый рециркулированный поток. Сжатый рециркулированный поток охлаждается, расширяется при более низком давлении, а затем подается в качестве сырья в верхнюю зону первого устройства абсорбции. Поток отгонного конденсата из нижней второго устройства абсорбции нагревается в устройстве тепломассообмена, освобождаясь от летучих компонентов.
