Abstract

En fremgangsmåte for å kontrollere en undervanns syklonseparator (5) i et undervanns prosessenngssystem for undervanns separasjon er beskrevet. Syklonseparatoren (5) er tilpasset til å separere hydrokarboner fra vann. Dette innbefatter å dirigere en hovedsakelig vanninneholdende væske inn i inntaket (4) av syklonseparatoren (5), ekstrahere en strømning som inneholder den vesentlige delen av hydrokarbonene fra et overløp (6) av syklonseparatoren (5) og hovedsakelig vann fra et underløp (7) av syklonseparatoren (5). Overløpet (6) og underløpet (7) er individuelt trykksatt av pumper (8, 9), der forholdet mellom pumperatene til pumpene (8, 9) bestemmer flow-spliten til syklonseparatoren (5). De individuelt trykksettende pumpene (8, 9) er drevet av en felles motor (10) og forholdet mellom pumperatene er satt til å korrespondere med et valgt trykkforhold som korresponderer med valgt flow-split av syklonseparatoren (5).A method of controlling an underwater cyclone separator (5) in an underwater process underwater separation system is described. The cyclone separator (5) is adapted to separate hydrocarbons from water. This includes directing a substantially water-containing liquid into the inlet (4) of the cyclone separator (5), extracting a flow containing the substantial portion of the hydrocarbons from an overflow (6) of the cyclone separator (5) and substantially water from an underflow (7). of the cyclone separator (5). The overflow (6) and underflow (7) are individually pressurized by pumps (8, 9), where the ratio of the pump rates to the pumps (8, 9) determines the flow split of the cyclone separator (5). The individual pressure setting pumps (8, 9) are driven by a common motor (10) and the ratio of the pump rates is set to correspond to a selected pressure ratio corresponding to the selected flow split of the cyclone separator (5).
