Near-critical fluid-assisted integrated liquefaction-extraction (nile) systems and methods for processing organic materials

A system comprising:

• one or more supplies of one or more solvents;
• a reactor;
• a fluidic network interconnecting the one or more supplies and the reactors;
• and
• a controller comprising one or more processors and one or more non-transitory computer-readable storage media, the computer-readable storage media storing computer-readable instructions that, when executed by the one or more processors, cause the system to:
• provide organic feedstock in the reactor with the one or more solvents via the fluidic network, the one or more solvents in the reactor comprising a supercritical fluid;
• subject the organic feedstock and the one or more solvents in the reactor to one or more conditions that cause liquefaction of the organic feedstock, so as to convert the organic feedstock into biocrude and one or more by-products;
• and
• flow the one or more solvents with the biocrude dissolved therein from the reactor via the fluidic network, such that the biocrude is separated from the one or more by-products.
