Abstract
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.
Claims16
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.
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. %.
