A simulated moving bed flushing apparatus and its use are described. The adsorber comprises a plurality of beds (10, 11) of adsorbent, each bed being connected to a distribution means (5) comprising two fluid distribution lines (2,1,) the first distribution line (2) of each distribution means being connected to at least one inlet (7) for feed and to at least one raffmate outlet (8), the other line 1 being connected to at least one solvent inlet (3) and to at least one extract outlet (4), each inlet and outlet comprising an on-off valve (7a, 8a, 3a, 4a), the first distribution line (2) comprising a flushing valve (9), and all of the flushing valves (9) relating to all of the distribution lines (2) are connected to means (100, 102) for circulating a fluid to be displaced. FIG. 1 to be published.
A flushing apparatus in a unit for separating a product from a feed using simulated moving bed adsorption, comprising a plurality of serially connected beds (10, 11) each containing adsorbent, characterized in that each bed is connected to a distribution means (5) comprising a first and a second fluid distribution line (2,1), the first distribution line (2) of each distribution means being connected either to at least one inlet (7) for a feed and to at least one outlet (8) for an effluent which is depleted in the product, or to at least one solvent inlet (3) and to at least one outlet (4) for an effluent which is rich in the product, the second line (1) being connected to at least one inlet and to at least one outlet which are not connected to said first line (2), each inlet and outlet comprising an on-off valve (7a, 8a, 3a, 4a), said first distribution line (2) comprising at least one flushing valve (9), downstream of valves of a supply line and a withdrawing line, all of the flushing valve or valves (9) relating to all of the first distribution line or lines (2) being connected to means (100,102) for circulating a fluid to be displaced;
A flusing apparatus in a unit for separating a product from a feed using simulated moving bed adsorption, comprising a plurality of serially connected beds (10, 11) each containing adsorbent, characterized in that each bed is connected to a distribution means (5) comprising a first and a second fluid distribution line (2,1), the first distribution line (2) of each distribution means being connected either to at least one inlet (7) for a feed and to at least one outlet (8) for an effluent which is depleted in the product, or to at least one solvent inlet (3) and to at least one outlet (4) for an effluent which is rich in the product, the second line (1) being connected to at least one inlet and to at least one outlet which are not connected to said first line (2), each inlet and outlet comprising an on-off valve (7a, 8a, 3a, 4a), said fast distribution line (2) comprising at least one flushing valve (9), all of the flushing valve or valves (9) relating to all of the first distribution line or lines (2) being connected To means (100,102) for circulating a fluid to be displaced;
A flushing apparatus in a unit for separating a product from a feed using simulated moving bed adsorption, comprising a plurality of serially connected beds (10, 11) each containing adsorbent, characterized in that each bed is connected to a distribution means (5) comprising a first and a second fluid distribution line (2,1), the first distribution line (2) of each distribution means being connected either to at least one inlet (7) for a feed and to at least one outlet (8) for an effluent which is depleted in the product, or to at least one solvent inlet (3) and to at least one outlet (4) for an effluent which is rich in the product, the second line (1) being connected to at least one inlet and to at least one outlet which are not connected to said first line (2), each inlet and outlet comprising an on-off valve (7a, 8a, 3a, 4a), said first distribution line (2) comprising flushing means for removal of fluid from said first distribution line (2), said flushing means comprising at least one flushing valve (9), all of the flushing valve or valves (9) relating to all of the first distribution line or lines (2) being connected to means (100,102) for circulating a fluid to be displaced;
A flushing apparatus in a unit for separating a product from a feed using simulated moving bed adsorption, comprising a plurality of serially connected beds (10, 11) each containing adsorbent, chacterized in that each bed in a closed loop inside an absorber is connected to a distribution means (5) comprising a first and a second fluid distribution line (2,1), the fist distribution line (2) of each distribution means being connected either to at least one inlet (7) for a feed and to at least one outlet (8) for an effluent which is depleted in the product, or to at least one solvent inlet (3) and to at least one outlet (4) for an effluent which is rich in the product, the second line (1) being connected to at least one inlet and to at least one outlet which are not connected to said first line (2), each inlet and outlet comprising an on-off valve (7a, 8a, 3a, 4a), said first distribution line (2) comprising at least one flushing valve (9), all of the flushing valve or valves (9) relating to all of the first distribution line or lines (2) being connected to means (100,102) for circulating a fluid to be displaced;
