Problems solved by technology

For solid asphaltenes, this method would require 10-20 times more solvent for delivery, and this amount of expensive solvent would be consumed in the process and the value of the solid asphaltenes would be reduced

Embodiment Construction

[0160] The following detailed description, given in conjunction with the accompanying drawings, is intended to illustrate various embodiments of the invention and is not intended to represent all embodiments contemplated by the inventors. The detailed description includes specific details for the purpose of providing a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details.

[0161] figure 1 is a process flow diagram illustrating a process 10 for forming a hydrocarbon product 60 from a hydrocarbon feedstock 12 in which the final hydrocarbon product 60 has properties sufficient to meet minimum pipeline transportation requirements (minimum API gravity of 19), which is compelling Satisfied Refinery Feedstock. Process fluid 14 formed from heavy hydrocarbon feedstock 12 may be heated to a desired temperature level via heater 20 prior to entering reactor 30...

Abstract

The present invention relates to a method of improving a heavy hydrocarbon, such as bitumen, to a lighter more fluid product and, more specifically, to a final hydrocarbon product that is refinery-ready and meets pipeline transport criteria without the addition of diluent. A solid asphaltene by-product is created for easy handling and further processing. The invention is targeted to enhance Canadian bitumen, but has general application in improving any heavy hydrocarbon. The process comprises: (a) pre-heating a process fluid in a heater to a designed temperature; (b) moving the pre-heated process fluid to a reactor, and optimally converting asphaltenes in the process fluid within the reactor to produce a stream of thermally affected asphaltene-nch fraction( s), and a stream of non-condensible vapour and lighter liquid hydrocarbon(s); (c) deasphalting the thermally affected asphaltene-nch stream with a solvent extraction process into a stream of heavy deasphalted oil (DAO) and a second stream containing concentrated asphaltene; (d) separating dry thermally affected asphaltene solids from the second stream in a separation unit, recovering the process solvent; (e) a produced refinery feedstock comprising at least one of the produced streams.

Description

technical field [0001] The present invention relates to a method for improving heavy hydrocarbons, such as bitumen, into a lighter, more fluidized product, and more specifically, refinery-ready and capable of meeting pipeline transport standards without the need for the addition of diluents process for the final hydrocarbon product. A solid asphaltene by-product is produced which is easily handled and further processed. The purpose of this invention is to improve Canadian bitumen, but it has general applicability to the improvement of any heavy hydrocarbon. Background technique [0002] Refining sweet crude resources requires less capital investment and is much less expensive to process than heavy sour crude. However, the global availability of light, sweet crude oil supplied to refineries to produce transportation fuels is decreasing, making the processing of heavy, sour crude oil an increasingly important option to meet global demand for hydrocarbon fuels. [0003] Most...
