  • Patent number: 11266924
    Abstract: Selective recovery of C2 to C4 hydrocarbons is achieved through the use of a converging-diverging nozzle, or de Laval nozzle. The vapor stream comprising C2 to C4 hydrocarbons is fed into an inlet of a de Laval nozzle having a throat. The vapor stream may have an initial temperature of between 0° C. and 100° C., and an initial pressure of between 200 psig and 500 psig. In the de Laval nozzle, the vapor stream expands after passing through the throat of the de Laval nozzle, producing a vapor stream having re-duced temperature and pressure. Then, C2 to C4 hydrocarbons condense from the reduced-temperature vapor stream as liquid droplets, which may be recovered. Fractionation of C2 to C4 hydrocarbons by means of a de Laval nozzle is possible; the technique allows select-ive recovery of propane from a mixture of propane and ethane.

  • Patent number: 11268036
    Abstract: Conversion of heavy fossil hydrocarbons (HFH) to a variety of value-added chemicals and/or fuels can be enhanced using microwave (MW) and/or radio-frequency (RE) energy. Variations of reactants, process parameters, and reactor design can significantly influence the relative distribution of chemicals and fuels generated as the product. In one example, a system for flash microwave conversion of HFH includes a source concentrating microwave or RF energy in a reaction zone having a pressure greater than 0.9 atm, a continuous feed having HFH and a process gas passing through the reaction zone, a HFH-to-liquids catalyst contacting the HFH in at least the reaction zone, and dielectric discharges within the reaction zone. The HFH and the catalyst have a residence time in the reaction zone of less than 30 seconds. In some instances, a plasma can form in or near the reaction zone.

  • Patent number: 11260398
    Abstract: A substantially vertical separating column of a waste-product treatment apparatus has a cylindrical body with holes in a lateral surface, inferiorly of a waste-product supply opening. A bladed shaft rotates coaxially inside the cylindrical body. A first discharge mouth in an upper part of the cylindrical body expels a first waste-product recycling fraction, the fraction separated and transported upwards by the bladed shaft. A dilution group along the separating column supplies dilution liquid internally of the cylindrical body. A second discharge mouth in the lower part of the cylindrical body evacuates a second recycling fraction. A discharge conduit and a screw extend parallel to a tangent to the cylindrical body, facilitating extraction of the first recycling fraction to the discharge conduit. The bladed shaft comprises a rotor and, in proximity of the upper end, a plate fixed to a lateral rotor surface and arranged radially.

  • Patent number: 11149212
    Abstract: A multi-phase process involves physical and chemical methods to recover the oil bases of used oils. The resulting oil base meets the standards and technical specifications necessary for reuse in the formulation of lube oils, greases and alike. The process includes classifying the used oil according to its physicochemical characteristics in order to optimize the subsequent phases. Next, the used oil is subject to physical pre-treatment to remove the solids of about 20 microns, dehydrate them and extinguish the remains of light hydrocarbons. Afterwards, the used oil undergoes extraction with organic chemical solvents on specific proportions within certain pressure and temperature ranges. The output is an extract composed of the oil base, the solvents and a semi-solid precipitate containing the used oil pollutants. Next, the extract is separated from the precipitate by physical methods. Subsequently, the extract passes through another physical procedure that separates the solvents from the oil base.
