Abstract
An aqua-ammonia absorption apparatus generator assembly comprising a boiler section, a solution-heated-desorber section, and adiabatic desorber or GAX desorber section, and a rectifier section, incorporates a plurality of columns, each column comprising one or more of the sections, with the columns arranged so that the lowest end of a first column is lower than the top end of a second column, and uses one or more eductors driven by a feed stream from the absorber for pumping liquid refrigerant from the bottom of a lower temperature column to the top of the next hotter column.

An aqua-ammonia absorption apparatus comprising an absorber assembly, a generator assembly, a condenser and an evaporator, said generator assembly comprising a boiler section, a solution-heated-desorber section, an adiabatic desorber or GAX desorber section, and a rectifier section, wherein said generator assembly comprises a plurality of columns, each column comprising one or more of said sections, said columns arranged so that the lowest end of a first column is lower than the top end of a second column, and one or more eductors driven by a feed stream from the absorber for pumping liquid refrigerant from the bottom of a lower temperature column to the top of the next hotter column.
An aqua-ammonia absorption apparatus comprising an absorber assembly, a generator assembly, a condenser and an evaporator, said generator assembly comprising a plurality of columns, a first column comprising a rectifier, and the other of said plurality of columns comprising a boiler, a solution-heated desorber, and an adiabatic desorber or a GAX desorber section, said columns arranged such that the bottom of the first column is lower than the top of a second column, said apparatus including a solution pump for pumping liquid solution therein, and first piping for directing liquid from the bottom of the fist column to the inlet of the solution pump and second piping for directing liquid solution from the solution pump to the top of the second column.
