Abstract
Mass transfer process, in which, in at least two contact stages, and at least two liquid or gaseous phases are brought into contact with one another, at least one component being transferred between the phases and the phases moving countercurrently. The flow through at least one of the contact stages is batchwise for one phase and continuous for another phase. The phases flow through contact stages which are formed by trays in a column, which trays are opened periodically so that the phase which flows through the column in a batchwise manner flows to the next tray.
Claims31
Mass transfer process, in which, in at least two contact stages, at least two liquid or gaseous phases are brought into contact with one another, at least one component being transferred between the phases and the phases moving countercurrently, wherein the flow through at least one of the at least two contact stages is batchwise for one phase and continuous for another phase and wherein the phases flow through contact stages which are formed by trays in a column, which trays are opened periodically so that the phase which flows through the column in a batchwise manner flows to the next tray.
Mass transfer process, in which, in at least two contact stages, and at least two liquid or gaseous phases are brought into contact with one another, at least one component being transferred between the phases and the phases moving countercurrently, wherein the flow through at least one of the contact stages is batchwise for one phase and continuous for another phase and wherein the phases flow through contact stages which are formed by separate vessels which are coupled to one another such that, by diverting the phase which passes through the at least two contact stages continuously, the batchwise phase can remain in the same vessel throughout the entire process.
Mass transfer process, in which, in at least two contact stages, and at least two liquid or gaseous phases are brought into contact with one another, at least one component being transferred between the phases and the phases moving countercurrently, in which the flow through at least one of the contact stages is batchwise for two phases.
Mass transfer process, in which, in at least two contact stages, and at least two liquid or gaseous phases are brought into contact with one another, at least one component being transferred between the phases and the phases moving countercurrently, wherein the flow through at least one of the at least two contact stages is batchwise for one phase and continuous for another phase, with the proviso that at least one of the phases is a gaseous phase.
Device for mass transfer, comprising
- a reservoir with a top and a bottom;
- a feed (1) in the top and a discharge (4) in the bottom, for feeding and discharging a phase;
- a feed (2) in the bottom and a discharge (3) in the top, for feeding and discharging another phase;
- at least two contact stages (S) in which one phase is brought into contact with another phase;
- the at least two contact stages being such that one phase flows through the contact stage in a batchwise manner and the other phase flows through the contact stage continuously and the at least two contact stages being trays which can be emptied periodically so that the phase which is flowing in a batchwise manner is able to move to the next contact stage.
