Abstract
A process for reaction and separation which comprises inputting a process material into at least one column of a plurality of columns wherein each column has at least one inlet for accepting flow from another column or group of columns, an external feed stream, an external eluent stream or a combination thereof, and each column has at least one outlet for connecting to another column, a group of columns, an external product stream or a combination thereof. Each column is independently operable in an up-flow or down-flow mode and connected independently to one of the group comprising another column, an external feed stream, an external eluent stream, an external product stream and combinations thereof.
Claims19
A process for the production of reaction products and separation products from a chemical reaction and separation using a liquid-solid contacting apparatus which comprises:
- (a) inputting a non-ionic process material into at least one column of a plurality of columns packed with media, each said column having at least one inlet for accepting a flow of said process material from another column or group of columns, an external feed stream, an external eluent stream or a combination thereof, and at least one outlet for connecting to another column, a group of columns, an external product stream or a combination thereof;
- each said column being independently operable in an up-flow or down-flow mode and connected independently to one of the group comprising another column, an external feed stream, an external eluent stream, an external product stream and combinations thereof, wherein at least two of said column inlets are available to selectively create a parallel flow respectively therethrough and wherein some but not all said columns are connected in series having a unidirectional flow respectively therethrough;
- (b) reacting and separating said non-ionic process material in one or more said columns;
- and
- (c) extracting non-ionic material therefrom.
A process for the production of non-ionic reaction products and non-ionic separation products by a substantially continuous chemical reaction and separation using a plurality of columns having upper and lower ports to selectively serve as inlets or outlets that selectively connect one or more of said other columns for upflow or downflow therethrough and wherein some but not all said columns are serially connected for unidirectional flow, said process comprising:
- (a) directing at least one non-ionic process material into an inlet of at least a first selected column;
- (b) initiating separation of said non-ionic process material in at least said first selected column;
- (c) reacting said non-ionic separation product wherein said reaction product accumulates in one or more columns;
- and
- (d) extracting said non-ionic reaction product therefrom.

- (a) directing at least one non-ionic process material into an inlet of at least a first selected column to prepare a non-ionic reaction product;
- (b) initiating a reaction of said non-ionic process material in at least said first selected column;
- (c) separating said non-ionic reaction product wherein said non-ionic reaction product accumulates in one or more columns;
- and
- (d) extracting said reaction product therefrom.
