Abstract

A supercritical fluid extraction system including a housing, motor, linkage assembly, and carriage coupled to the linkage. A piston assembly includes a piston housing with a chamber, back check valve, and piston coupled to the carriage and movable within the piston housing. The piston assembly includes a fluid inlet fluidly communicating with the chamber, and receives, compresses, and expels fluid into an exit fluid line. An intake manifold receives fluid and provides an inlet pathway to the fluid inlet. A single-pass flow path fluidly connects the exit fluid line and a collection chamber, extending through the exit fluid line, a compression chamber, a flow modulator assembly, and the collection chamber. The fluid extracts liquid from solid material within the compression chamber when at a minimum pressure within the compression chamber, passes through the flow modulator assembly and precipitates the extracted liquid into the collection chamber when below the minimum pressure.
