Abstract

"MéTODO E INSTALAçãO PARA ENRIQUECIMENTO DE UMA CORRENTE DE GáS COM UM DOS COMPONENTES DO MESMO". A invenção se refere a um método de enriquecimento de uma corrente de gás pressurizado (1) com um dos componentes (A) da mesma. O método inventivo compreende as etapas a seguir: a corrente é separada em pelo menos uma primeira e uma segunda frações (2, 3) pelo menos uma parte da primeira fração (2) é enviada para uma unidade de separação (ASU); a unidade de separação supre pelo menos duas descargas, incluindo uma primeira descarga (10) que tem um teor de A maior do que aquele da fração (2) suprida para a unidade de separação; pelo menos uma parte da primeira descarga (10) é misturada com pelo menos uma parte da segunda fração (3), de modo a formar uma mistura de gás pressurizado (15); a segunda fração (3) é expandida e, subseqüentemente, pelo menos uma parte da primeira descarga (10) é misturada ali."METHOD AND INSTALLATION FOR ENRICHING A GAS CURRENT WITH ONE OF THE SAME COMPONENTS". The invention relates to a method of enriching a pressurized gas stream (1) with one of its components (A). The inventive method comprises the following steps: the stream is separated into at least a first and a second fraction (2, 3) at least a portion of the first fraction (2) is sent to a separation unit (ASU); the separation unit supplies at least two discharges, including a first discharge (10) having an A content greater than that of the fraction (2) supplied to the separation unit; at least a portion of the first discharge (10) is mixed with at least a portion of the second fraction (3) to form a pressurized gas mixture (15); the second fraction (3) is expanded and subsequently at least a portion of the first discharge (10) is mixed there.
