Abstract (en)

[origin: WO2004041426A1] Vapor and liquid flows concurrently through a vertical vessel in a catalytic reactor (1). A horizontal flow obstructing mixing box (8) is located within the vessel and forces the vapor and liquid to pass in a vertical direction through one or more entrances to the horizontal mixing box. The mixing box consists of circular top (13) and bottom (14) walls and a cylindrical side wall (15). Inside the mixing box vertical flow baffles (18, 19, 20) are provided. These flow baffles form one or more mixing orifices (21, 22). The entire process stream is flowing through each mixing orifice at high flow velocity. Each mixing orifice is followed by a tee where the process stream is divided into two tower velocity streams. In the transition from high flow velocity in the mixing orifice to lower flow velocity in the divided streams, turbulent flow conditions are generated. In the lower velocity divided streams hold-up time is provided to allow for heat and mass transfer. The flow inside the mixing box is mainly in the horizontal plane. The outlet stream from the mixer equilibrated regarding temperature and chemical composition.
