HEAT AND MASS EXCHANGERS HAVING EXTRUDED PLATES

摘要

A heat and mass exchanger including a plurality of vertical plates that are spaced apart from one another by gaps so as to allow a first gas to flow between the plates. Each plate includes a front wall that defines a front surface of the plate, a back wall that defines a back surface of the plate, and separate, parallel channels disposed between the front and back walls. The parallel channels include a first set of parallel channels, a first liquid flowing within the first set of channels and over one of the front or back surfaces of the plate, the first liquid having a bulk composition comprising one or more constituents, the first gas having at least one constituent in common with the first liquid, and a second set of parallel channels, a first fluid flowing within the second set of channels.

主权项

1. A heat and mass exchanger that exchanges heat and/or mass between a first gas stream and a first liquid stream while simultaneously heating or cooling the first liquid stream, the heat and mass exchanger comprising:
a plurality of vertical plates that are spaced apart from one another by gaps so as to allow a first gas to flow between the plates, each plate comprising:
a front wall that defines a front surface of the plate;a back wall that defines a back surface of the plate; andparallel channels disposed between the front and back walls, each parallel channel being separated from a neighboring channel over at least a portion of the total length of the channel by a web, the parallel channels comprising:
a first set of parallel channels, a first liquid flowing within the first set of channels and over one of the front or back surfaces of the plate, the first liquid having a bulk composition comprising one or more constituents, the first gas having at least one constituent in common with the first liquid; anda second set of parallel channels, a first fluid flowing within the second set of channels.
