Title (EN) A METHOD FOR CONTROLLED OUTGASSING OF CRUDE OIL
(FR) METHODE DE DEGAZAGE CONTROLE DU PETROLE BRUT
Abstract:
(EN) A method for controlled outgassing of crude oil in the cargo tanks of a tanker. The gases are intended to be utilized as an energy source, e.g. for the propulsion of the tanker. The outgassing is accelerated by introducing inert gas (I) and/or tank gas (T) into the tanks with an adjustable flow and thereby achieving an agitation of the oil and an increase of the phase interface liquid-gas. By the fact that said flow is adjustable the outgassing process can be controlled.
(FR) Methode de degazage controle du petrole brut contenu dans les reservoirs d"un petrolier. Le but est d"utiliser les gaz comme source d"energie, par exemple pour la propulsion du petrolier. Le degazage est accelere en introduisant un gaz inerte (1) et/ou un gaz de reservoir (T) dans les reservoirs avec un debit reglable, produisant ainsi une agitation du petrole et une augmentation de l"interface de la phase liquide-gaz. Compte tenu du fait que le debit est reglable, il est possible de controler le procede de degazage.
