Process for upgrading heavy oil and bitumen products

A process for upgrading bitumen recovered from an oil reservoir without hydrogen production is particularly useful in field upgrading applications. In this process, recovered bitumen enters a fractionator and is contacted with heated gases from a fluidized bed reactor. The bitumen and heated gases are fractionated into segregated products including at least a liquid pitch, unstable fractions, and an upgraded liquid product. The liquid pitch is introduced into the reactor to produce a vapor phase liquid product; the reactor comprises solid particles moving through the reactor and a fluidizing gas fluidizing the solid particles at a conversion temperature which is suitable for facilitating the conversion of at least some of the liquid pitch into the vapor phase liquid product. The heated gases comprising the vapor phase liquid product and fluidizing gas are directed from the reactor to the fractionator to contact the bitumen stream. In this process, enough of the segregated unstable fractions are burned that the liquid product and any remaining unstable fractions meets pipeline specifications without hydrogen treatment of any of the remaining unstable fractions.

Method and device for carrying out a thermodynamic cyclic process

In accordance with the invention, to reduce the complexity of a cycle process, a liquid working medium flow (13) is brought up to an increased pressure and through part condensation of an expanded working medium flow (12) a first partly vaporized working medium flow (15) is created. Through further vaporization of the first partly vaporized working medium flow (15) with heat which is transferred from an external heat source (20), a second at least partly vaporized working medium flow (18) is created. In this second at least partly vaporized working medium flow (18) the vapor phase (10) is separated from the liquid phase (10), subsequently the energy of the vapor phase (10) is converted into a usable form and an expanded vapor phase (11) created. The expanded vapor phase (11) is mixed with the liquid phase (19) and the expanded working medium flow (12) is formed. Through complete condensation of the partly condensed, expanded working medium flow (12a) the liquid working medium flow (13) is obtained in its turn.
