Abstract:
1. A method for manipulating or formulating a solid substance which melts under pressure of a gas without degrading at a temperature which is lower than the melting point of the substance at atmospheric pressure comprising: providing the substance in a pressure chamber having an inlet and an outlet, wherein the outlet is above the inlet; applying to the substance a liquefied gas or dense gas to melt the substance without degrading the substance; equilibrating the molten substance and the liquefied gas or dense gas to form a homogeneous solution wherein the solution is maintained below saturation; and contacting the solution with a carrier fluid, wherein the carrier fluid is passed through the solution and is at substantially the same pressure as the liquefied gas or dense gas, to pass the solution from the pressure chamber through the outlet into a vessel of lower pressure than the pressure of the liquefied gas or dense gas and carrier fluid, and wherein further the solution is maintained below saturation.
