Systems and methods for renewable fuel
View Patent ↗The present application generally relates to the introduction of a renewable fuel oil as a feedstock into refinery systems or field upgrading equipment. For example, the present application is directed to methods of introducing a liquid thermally produced from biomass into a petroleum conversion unit; for example, a refinery fluid catalytic cracker (FCC), a coker, a field upgrader system, a hydrocracker, and/or hydrotreating unit; for co-processing with petroleum fractions, petroleum fraction reactants, and/or petroleum fraction feedstocks and the products, e.g., fuels, and uses and value of the products resulting therefrom.
1. A method of upgrading crude oil, comprising: co-processing the crude oil and an unenriched renewable fuel oil as reactants in a field upgrader system, said field upgrader system comprising:
(a) one or more units configured to remove water, sand, and physical waste from the crude oil to form a reduced-contaminant crude oil;
(b) a hydrotreating unit; and
(c) a hydrogenation unit configured to co-process the reduced-contaminant crude oil and the unenriched renewable fuel oil.
2. The method of claim 1 , wherein the unenriched renewable fuel oil is 0.05-20 wt. % of the reactants and the crude oil is 80-99.95 wt. % of the reactants.
3. The method of claim 1 , wherein the unenriched renewable fuel oil is the product of a mechanical and thermal conversion of a cellulosic biomass comprising grinding and non-catalytic rapid thermal processing.
4. The method of claim 3 , wherein the non-catalytic thermal processing of the cellulosic biomass converts at least 60 wt. % of the cellulosic biomass to the unenriched renewable fuel oil.
5. The method of claim 4 , wherein the unenriched renewable fuel oil comprises: a carbon content of at least 40 wt. % on a moisture-free basis, an oxygen content in the range of between 20-50 wt. % on a moisture-free basis, and a water content in the range of between 10-40 wt. %.
6. The method of claim 5 , wherein the unenriched renewable fuel oil is 0.05-20 wt. % of the reactants and the crude oil is 80-99.95 wt. % of the reactants.
7. The method of claim 1 , wherein the crude oil is derived from West Canadian oil sands.
8. The method of claim 1 , wherein the hydrogenation unit is a carbon rejection unit.
9. The method of claim 1 , wherein the hydrogenation unit is a catalytic hydrocracker.
10. The method of claim 9 , wherein the non-catalytic thermal processing of the cellulosic biomass converts at least 60 wt. % of the cellulosic biomass to the unenriched renewable fuel oil.
11. The method of claim 10 , wherein the unenriched renewable fuel oil comprises: a carbon content of at least 40 wt. % on a moisture-free basis, an oxygen content in the range of between 20-50 wt. % on a moisture-free basis, and a water content in the range of between 10-40 wt. %.
12. The method of claim 11 , wherein the unenriched renewable fuel oil is 0.05-20 wt. % of the reactants and the crude oil is 80-99.95 wt. % of the reactants.
13. The method of claim 9 , wherein the crude oil and the unenriched renewable fuel oil are co-blended prior to co-processing.
14. The method of claim 1 , wherein the reduced-contaminant crude oil and the unenriched renewable fuel oil are co-blended prior to introduction to the hydrogenation unit.
15. The method of claim 1 , wherein the reduced-contaminant crude oil and the unenriched renewable fuel oil are introduced to the hydrogenation unit through separate inlet ports.
16. A method of upgrading crude oil, comprising: co-processing the crude oil and an unenriched renewable fuel oil as reactants in a field upgrader system, said field upgrader system consisting essentially of:
(a) one or more units configured to remove water, sand, and physical waste from the crude oil to form a reduced-contaminant crude oil;
(b) a hydrotreating unit; and
(c) a hydrogenation unit,
the unenriched renewable fuel oil comprising a product of grinding and non-catalytic rapid thermal processing to convert at least 60 wt. % of a cellulosic biomass to the unenriched renewable fuel oil, the unenriched renewable fuel oil having a carbon content of at least 40 wt % on a moisture-free basis, an oxygen content in the range of between 20-50 wt. % on a moisture-free basis, and a water content in the range of between 10-40 wt. %.
