Description: The process of treating a chemical compound and/or microorganism transported by a liquid and/or a gas, comprises circulating a liquid in a flow space in which conditions of liquid flow are adapted to produce cavitation bubbles or pockets and to provoke collision and impulsion in the bubbles or pockets, and injecting an incondensable gas inside the bubbles or pockets. The flow space comprises, between two walls, a radial chamber having an axial opening for introducing the liquid in the walls in its central part and a peripheral opening for exiting the liquid in its side part.; The process of treating a chemical compound and/or microorganism transported by a liquid and/or a gas, comprises circulating a liquid in a flow space in which conditions of liquid flow are adapted to produce cavitation bubbles or pockets and to provoke collision and impulsion in the bubbles or pockets, and injecting an incondensable gas inside the bubbles or pockets. The flow space comprises, between two walls, a radial chamber having an axial opening for introducing the liquid in the walls in its central part and a peripheral opening for exiting the liquid in its side part.

MIXING TECHNOLOGIES:



 

Title: Process for mixing fluids with non-homogeneous properties

 

Applicant: SPRETEC

 

Description: Fluids forming strata in a vessel are extracted through a number of vertical perforated pipes. The perforations are regularly spaced and their total surface can be varied with the level of fluid in the vessel. The pipes join at their downstream ends to form a common circuit. The fluids extracted through the pipes match the overall mean mixture in the vessel. The pipes have a common point at their downstream end, where the fluids join a common circuit. The circuit contains mechanical means of extracting fluid from the vessel and circulating it. The perforations in the pipes are regularly spaced to form a regular supply in the vertical direction, which displaces the strata in the vessel horizontally and the extraction thus obtained has a composition of the different fluids in the same proportions as the mean in the vessel.; The supply to the pipes by gravity is ensured by opening a valve or by operating a pump. The total surface of the perforations is varied by using or not using some of the pipes, using valves  controlled by a level detector. The mixture can be reintroduced into the vessel, agitating the fluids in the vessel as little as possible. The mixture can pass into a final mixer to homogenize the extracted fluid even more finely.
