Method and device for absorbing gases or components of gas mixtures

Claim 2

Method according to claim 1, wherein the gas and liquid solvent are passed through a system subdivided into at least two column units each formed of at least one column so that the gas and liquid solvent traverse each unit in the same flow direction and pass through the system of units in opposite flow direction.

Claim 3

Method according to claim 1, wherein the gas and liquid solvent are passed through a system subdivided into a plurality of column units each formed of at least one column so that the gas and liquid solvent traverse each unit in the same flow direction, at least two of said column units being connected to form an opposing flow path therebetween and at least two being connected to form a flow path in the same direction therebetween.

Claim 4

Method according to claim 1, wherein the absorbing liquid solvent is guided in a circuit.

Claim 5

Method according to claim 1, wherein the liquid solvent is passed through a heat exchanger before being passed into the desorption column.

Claim 6

Method according to claim 1, wherein the liquid solvent is passed through a heat exchanger before being introduced into the absorption column.

Claim 7

Method according to claim 1, wherein the liquid solvent is discharged from the desorption column and is passed through a heater.

Claim 8

Method according to claim 1, wherein a hydrostatic pressure drop is employed for passing the liquid solvent in opposite flow direction to the gas between the units.

Claim 9

Method according to claim 3, including pumping the liquid solvent with at least one pump so as to pass the liquid solvent in opposite flow direction to the gas between the units.

Claim 10

Device for absorbing gases or components of gas mixtures, comprising at least one absorbing column having a plurality of vertically spaced filter plates formed of highly porous sintered material bodies having flow-through openings through the pores of said highly porous sintered material bodies, at least one desorption column connected to said absorbing column and having vertically spaced filter plates similar to those in said absorbing column, and including first means located below the top of said absorbing column for introducing an upwardly guided flow of gas into said absorbing column, and second means located below the top of said absorbing column for introducing into said absorbing column a liquid solvent for absorbing the gas so that the liquid solvent is entrainable by the gas and passes therewith in the same direction through said absorbing column and said desorption column.

Claim 11

Device according to claim 11, including a heAt exchanger connected between said absorbing column and said desorption column.

Claim 12

Device according to claim 11, wherein the pores of the respective filter plates are fifty per cent by volume of said plates.

Claim 13

Device according to claim 11, wherein said filter plates are formed predominantly with open pores.

Claim 14

Device according to claim 11, wherein the ratio of the thickness of the porous filter plates to the diameter thereof is greater than 0.1.

Claim 15

Device according to claim 11, wherein the ratio of the diameter of said flow-through openings to the thickness of said porous plates is between 0.03 and 0.3.

Claim 16

Device according to claim 11, including at least one column formed of at least two subdivided sections, said sections being connected to one another to form a flow path therebetween in the same flow direction.

Claim 17

Device according to claim 11, including at least one column formed of at least two subdivided sections, said sections being connected to one another to form a flow path therebetween in opposite flow directions.

Claim 18

Device according to claim 11, including at least one column formed of a plurality of subdivided sections, at least two of said sections being connected to one another to form a flow path therethrough in the same direction and at least two of said sections being connected to one another to form a flow path therethrough in opposite flow direction.

Claim 19

Device according to claim 11, including outlet shafts connected to said absorbing column.

Claim 20

Device according to claim 11, including a plurality of columns connected as a unit, a plurality of reversing channels being located between pairs of the columns in said units for connecting the same to one another.

Claim 21

Device according to claim 11, wherein a plurality of columns are connected in individual units, said units being in turn connected to one another, and including a pump connected between a pair of said connected units.
