English Abstract



The invention describes a configured fixed fluid transfer facility for tanker
trucks and railroad
tank cars to arrange, facilitate and manage a plurality of fluid streams and
cam accurately load
and unload tanker trucks and railroad tank cars, segregate the unloaded fluid
streams into distinct
product flows which may include bitumen, and combinations of hydrocarbon or
process fluids
typical in petroleum extraction and production of heavy oil, and manage the
fluids through
configurable conduits and heated buffer storage tanks to unlock the prior
art's dependency
between the railcar and truck transloading. The facility can minimize loss and
blending in the
processes, and some treatment or mixing of various streams may be effected.
Heat is applied to
portions of the system to reduce certain fluids' viscosity and minimize time
required to load and
unload viscous fluids to or from the facility, making the transshipment and
logistical
management of these products efficient.


French Abstract

L'invention décrit une installation de transfert des fluides fixe configurée pour que les camions-citernes et les wagons-citernes puissent planifier, faciliter et gérer une pluralité de courants fluides et que la came charge et décharge de manière précise les camions-citernes et les wagons-citernes, sépare les courants fluides dans divers flux de produits qui peuvent inclure du bitume, et des combinaisons de fluides d'hydrocarbures ou de traitement typiques dans l'extraction du pétrole et la production de pétrole lourd, et gérer les fluides avec des conduites configurables et des bacs tampons de stockage chauffés pour déverrouiller la dépendance antérieure entre le transbordement des camions et wagons. Cette installation peut minimiser les pertes et fusionner les processus, ce qui pourrait toucher le traitement ou le mélange de divers courants. De la chaleur est appliquée à des portions du système pour réduire la viscosité de certains fluides et minimiser le temps requis pour charger et décharger les fluides visqueux vers ou en provenance de l'installation, améliorant le transbordement et la gestion logistique de ces produits.
