Embodiment Construction

[0023] Referring now to the drawings, FIG. 1 illustrates a diagrammatic side view of a system 10 having a container or enclosure 12 disposed within a device 14 in accordance with certain embodiments of the present technology. The capsule 12 is chemically inert and impermeable to a material, a solvent, and a supercritical fluid formed from the solvent. The enclosure 12 is formed from a deformable material to allow the enclosure 12 to expand as the pressure in the enclosure 12 increases. This will prevent the capsule 12 from exploding. In one embodiment, the deformable material comprises copper, copper-based alloys, gold, silver, palladium, platinum, iridium, ruthenium, rhodium, osmium, titanium, vanadium, chromium, iron, iron-based alloys, nickel, nickel-based alloys , at least one of zirconium, niobium, molybdenum, tantalum, tungsten, rhenium, and combinations thereof. In another embodiment, the enclosure 12 is formed of a cold weldable material such as, but not limited to, ...

Abstract

An apparatus and method for processing materials in supercritical fluids is disclosed. The apparatus includes a capsule configured to contain a supercritical fluid, a high strength enclosure disposed about the capsule and a sensor configured to sense pressure difference between an interior and an exterior of the capsule. The apparatus also includes a pressure control device configured to adjust pressure difference of the capsule in response to the pressure difference sensed by the sensor. The apparatus further includes at least one dividing structure disposed within the capsule that divides the capsule into a seed growing chamber and a nutrient chamber.

Description

technical field [0001] The present invention generally relates to techniques for processing materials in supercritical fluids, and in particular, embodiments of the invention include techniques for controlling parameters related to material processing enclosures disposed in high pressure apparatus / housings. Background technique [0002] Supercritical fluids can be used to process a wide variety of materials. A supercritical fluid is defined as a substance that exceeds its critical point (ie, critical temperature and critical pressure). The critical point represents the highest temperature and pressure at which a substance can exist in gas-liquid equilibrium. In some supercritical fluid applications, the material being processed is placed inside a pressure vessel or other high pressure device. In some cases, it is desirable to first place the material inside the container, enclosure, or enclosure, which in turn is placed inside the high pressure device. In operation, the h...
