CO2 LIQUID FLOW REGULATING METHOD AND DEVICE AND USE THEREOF IN A COOLING TUNNEL

According to the process, there is maintained in a conduit (3), on the downstream side of a valve (5), up to the vicinity of the point A of injection of the CO2, an intermediate pressure (PI) higher than the pressure (PT) of the triple point of the CO2. Application in the treatment of waste waters o...

More Information
Summary:According to the process, there is maintained in a conduit (3), on the downstream side of a valve (5), up to the vicinity of the point A of injection of the CO2, an intermediate pressure (PI) higher than the pressure (PT) of the triple point of the CO2. Application in the treatment of waste waters or the deep freezing of food.
