CONTINUOUS PROCESS FOR PERFORMING A CHEMICAL REACTION IN WHICH A GASEOUS PHASE IS ADDED TO A CHARGE SYSTEM COMPRISING ONE OR MORE SOLID PHASES WHICH HAVE BEEN DISSOLVED OR DISPERSED IN WATER

摘要

A chemical reaction is performed by first adding the incoming stream to a shear zone of an apparatus by way of a feed upstream of the shear zone. The apparatus includes a rotor and a stator, with the shear zone being formed by facing surfaces of the rotor and the stator. The shear zone is followed by a mixing zone having an outlet toward an outside of the apparatus. A gage pressure of at least 1 bar is generated in the shear zone. The gaseous phase is mixed into the mixing zone through the aperture and into the incoming stream under the generated gage pressure to create a reaction mixture. The reaction mixture is fed to a residence-time zone via a downstream outlet from the mixing zone, where a reaction takes place, and pressure in the mixing zone is controlled using a downstream pressure-control valve.
