Definitions

  • the invention relates to a method for providing liquid overflow conditions on columns of a column during mass transfer with separate phase movements in tray columns in a gas-liquid system, and can be used in food, chemical, petrochemical, oil refining, and other industries.
  • Known mass transfer contact device providing a method of flowing liquid on the plates of the mass transfer apparatus, which operate in a mode with a separate movement of the phases.
  • the liquid flows from plate to plate through the transition tank when the pressure of the vapor stream on the plate changes.
  • the steam supply to the column is shut off, the pressure in the column drops. Since a certain boiling point corresponds to a given pressure and concentration of separable substances, the phenomenon of self-evaporation of an overheated liquid occurs. Secondary vapors undermine the valves from the sockets, causing an unauthorized failure of the liquid on the downstream plate.
  • the drawback of the operation of the contact device is the decrease in the efficiency of the column due to the mixing of the liquid when it flows from plate to plate.
  • the basis of the invention is the task of ensuring optimal operating conditions of apparatuses with separate phase motion — eliminating mixing of liquid on adjacent plates when liquid flows from plate to plate.
  • the problem is solved in that the movement of the vapor phase during the liquid flow is blocked at the inlet and outlet of the column.
  • the technical result of the proposed method is that the flow of liquid on the plates of the column without mixing reduces the energy consumption for the process, increases the productivity of the equipment, increases the separation efficiency.

Abstract

L'invention peut s'utiliser dans des industries alimentaire, chimique, pétrochimique, de transformation de pétrole ou autre. Le procédé pour assurer le transfert d'un liquide par écoulement sur les plateaux d'une colonne pendant un déplacement séparé des phases utilise des dispositifs de contact spéciaux, destinés à mettre en oeuvre le processus, qui se mettent en marche lors d'un changement de pression sur les plateaux. Selon l'invention, lors du transvasement du liquide on coupe la vapeur à l'entrée et à la sortie de la colonne. L'invention permet de réduire les dépenses en énergie lors du transvasement du liquide sur les plateaux de la colonne sans mélangeage, ce qui réduit les dépenses en énergie, augmente la productivité de l'équipement et améliore l'efficacité de séparation des composants.
