Abstract

A fluidized bed coking reactor apparatus comprises a reaction vessel; a temperature sensor inside the reaction vessel for measuring a reactor temperature, a solids feed mechanism for feeding solid particles into the reactor vessel at a mass flow rate, a feed material feed mechanism for feeding feed material into the reactor at an operating feed rate; and a supervisory controller programmed to determine an upper feed material feed rate of the reactor when operating at the reactor temperature and receiving solid particles at the mass flow rate. The upper feed material feed rate is defined as a feed rate of feed material deposited onto a selected fraction of a fluidized bed of solid particles that causes defluidization in the reactor when the reactor is operating under conditions having a selected degree of backmixing in the fluidized bed, wherein the degree of backmixing is modeled as a selected number of reactors arranged in series and each operating under continuous well-mixed conditions, with the selected number of reactors being an integer between one and infinity.

Abstract

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.
