Abstract

Det er beskrevet en destillasjonskolonne for separering av atmosfæriske gasser hvor det anvendes strukturert pakking med varierende krympvinkler l minst to seksjoner eller underseksjoner til en enkelt seksjon l en destillasjonskolonne. I tilfelle bruk av struk- turert pakking i flere seksjoner, er krympvinkelen til den strukturerte pakkingen som brukes i den første seksjonen større enn tilsvarende i den andre seksjonen og er valgt slik at begge seksjonene opererer ved samme maksimale designprosentandel av flømmlngsgrensen. Den økte krympvinkelen til den første seksjonen reduserer HETP til pakkingen og tillater derved en kolonneutfor- mlng med redusert høyde. Strukturert pakking med forskjellige krympvinkler kan brukes i en enkelt seksjon av en kolonne når en slik seksjon er utsatt for mulige variasjoner i dampmengden. Her blir krymp- vlnklene igjen manipulert slik at underseksjonene opererer ved samme maksimale designprosentandel av flømmingsgrensen. Den foregående tilpasningen forbedrer turndown ytelsen.
