SIGUIENDO ESTE PROCEDIMIENTO, SE MANTIENE EN EL CONDUCTO (3), COMO PROTECCION DE LA VALVULA (5), HASTA LA PROXIMIDAD DEL PUNTO (A) DE INYECCION DEL CO2, UNA PRESION INTERMEDIA (PI) SUPERIOR A LA PRESION (PT) DEL PUNTO TRIPLE DEL CO2. APLICACION AL TRATAMIENTO DE AGUAS RESIDUALES O A LA CONGELACION ALIMENTICEA. 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.
