Supercritical Water Separation Process

A supercritical water separation process and system is disclosed for the removal of metals, minerals, particulate, asphaltenes, and resins from a contaminated organic material. The present invention takes advantage of the physical and chemical properties of supercritical water to effect the desired separation of contaminants from organic materials and permit scale-up. At a temperature and pressure above the critical point of water (374° C., 22.1 MPa), nonpolar organic compounds become miscible in supercritical water (SCW) and polar compounds and asphaltenes become immiscible. The process and system disclosed continuously separates immiscible contaminants and solids from the supercritical water and clean oil product solution. The present invention creates a density gradient that enables over 95% recovery of clean oil and over 99% reduction of contaminants such as asphaltenes and particulate matter depending on the properties of the contaminated organic material.

Method and System for Directly Cracking Crude Oil to Prepare Olefin

A method for cracking crude oil includes delivering the crude oil to a first tube group of a convection section of a cracking furnace for preheating and then performing vaporization to obtain a first gas phase and a first liquid phase; performing high-pressure extraction on the first liquid phase to obtain a non-asphalt oil and an asphalt; and mixing the first gas phase and the non-asphalt oil with water vapor respectively, or mixing the first gas phase with the non-asphalt oil prior to mixing with water vapor, then delivering the same to a second tube group of the convection section of the cracking furnace for heating, followed by delivering same to a radiation section of the cracking furnace for cracking to obtain a cracked product, and separating the cracked product to obtain low-carbon olefins.

Dynamic interface system and its application in supercritical fluid extraction and chromatography

The present invention provides a dynamic interface system between an extraction device and a chromatographic purification device for separating and purifying substance(s) from a mixture or matrix. One embodiment is the Supercritical Fluid Interface (“SFI”) between Supercritical Fluid Extraction (“SFE”), and Supercritical Fluid Chromatography (“SFC”). The SFI is capable of interfacing; gas, subcritical and supercritical fluid extraction methods and pair with gas, subcritical and supercritical fluid chromatography technologies that operate within the pressure and temperature parameters of the SFI. The SFI can operate up to 200 degrees celsius and 5000 psi. This interface technology allows for an inline oil extraction and chromatographic separation, the SFI can pair extraction and chromatography with the same solvent in different mobile phases, whereas the extraction can be performed using CO.sub.2 as a solvent in sub-critical phase and the SFI can receive the subcritical solution and then increase pressure and/or temperature to achieve supercritical state as required for injection into supercritical fluid chromatography technologies. The SFI coupling between SFE and SFC can to extract and refine cannabinoids from the cannabis industrious, hemp, plant and can also be applied to improve efficiency in an industry that extracts and refines oils, through chromatography, from organic materials using a gas, or sub/supercritical fluid as a solvent and mobile phase.
