Using User Models to Improve Organizational Communication

A gas-liquid contact tower comprises an outer tower shell and a plurality of superimposed generally horizontal contact plates within the tower shell. The plates are grouped into at least one sub-assembly thereof, and an arrangement is provided for removably supporting the plate assembly within the tower shell. A baffle arrangement is mounted within the tower shell and adjacently overlying the plate sub-assembly and is shaped to minimize or substantially preclude splashing of the shell walls. The baffle arrangement includes a cylindrical section closely but removably fitted within adjacent wall surfaces of the tower shell and a frustoconical section for directing fluid from the cylindrical baffle section onto a contact plate immediately underlying the baffle arrangement. The cylindrical baffle section has sufficient height to afford that flow resistance which would substantially preclude flow of condensible vapor between the adjacent wall surfaces and the baffle arrangement.
