Various aspects of the disclosure relate to methods and systems for extracting plant oil from plant material. A system may comprise a microwave emitter, an extraction chamber, and a cooling chamber. Microwave radiation emitted by the microwave emitter may dielectrically heat a microwave absorbing agent, which may heat the plant oil of the plant material. Plant oil of the plant material may be volatized in the extraction chamber and may be directed into the cooling chamber to be condensed.

A steam heating type sewage treatment device includes: a treatment tank connected to a sewage supply pipe, a stirring device disposed in the treatment tank; a steam heating device disposed on an outer surface of the treatment tank; a vacuuming device fixed to a top of the treatment tank and connected to the treatment tank via a first connecting pipe; a heating device connected to the treatment tank by a second connecting pipe and connected to a steam storage tank by a third connecting pipe, and a fourth connecting pipe connected between the steam input pipe and the steam storage tank to recycle the steam. The heating device pressurizes or heats the steam entering the vacuuming device and the connecting pipes, and the heated steam is guided by pipes into the steam heating device, thus achieving the effect of steam recycling.

A desalination system includes a vertical column with a lower end submerged into a body of liquid to be treated. The column has a dark-colored outer surface able to absorb electromagnetic energy, and at least one vacuum compressor is connected to provide a vacuum pressure in the vertical column such that the liquid is drawn into the vertical column through openings in the vertical column. A condensing dome has a main shell and that receives vapor of the liquid in the vertical column via a vapor port joining the vertical column and the condensing dome. A wind-driven outer turbine surrounds the main shell of the condensing dome and draws outside air into a space around the main shell of the condensing dome. A tank is connected to the condensing dome via a pipe and receives desalinated liquid from the condensing dome.

Methods and systems are provided for processing cannabinoids and related compounds using a production system comprising an evaporator connected to a distillation unit and condenser column. The product may be collected from the condenser column by a collection system comprising one or more collection tanks. Subsequently, the product may be manually or automatically conveyed from the collection system to storage vessels operating under atmospheric conditions.

A method for separating a lubrication oil from a waste fluid includes separating water from the waste fluid including a lubrication oil by heating the waste fluid while sealed in a first vacuum chamber to a first maximum specified temperature and first specified pressure. Fuel oil is separated from a fluid received from the first vacuum chamber by heating the fluid while sealed in a second vacuum chamber to a second maximum specified temperature that his higher than the first maximum specified temperature and at a second specified pressure. Finally, the lubrication oil is separated from a fluid received from the second vacuum chamber by heating the fluid received from the second vacuum chamber while sealed in a third vacuum chamber to a third maximum specified temperature that his higher than the second maximum specified temperature and at a third specified pressure. The first, second and third pressures need not be different.

A contaminated water purification system includes a contaminated water storage tank and a contaminated water inlet manifold to transfer contaminated water to a reactor unit having a heater unit mounted therein. The heater unit is disposed and configured to contact the contaminated water in the reactor unit and convert an aqueous component of the contaminated water into purified steam. A purified steam discharge manifold is disposed between the reactor unit and a steam conversion chamber to transfer the purified steam to the steam conversion chamber which condenses the purified steam into purified water, while the contaminant component or components remain in the reactor unit. A purified water storage assembly includes a purified water storage tank to at least temporarily hold the purified water condensed from the purified steam in the steam conversion chamber.

Disclosed are methods, systems, and apparatuses for purifying liquids. One illustrative method includes generating an aerosol from a contaminated liquid. The illustrative method also includes generating a vapor from the aerosol by applying a negative pressure to the aerosol. The illustrative method further includes separating at least one type of contaminant particle from the vapor and converting the vapor into a liquid.

A process includes continuous steps and batch steps for recycling waste oil, fuel or antifreeze. The continuous steps include determining the volume of waste; pumping waste toward a distillation vessel; mixing waste with heated waste, and while flowing the waste into the distillation vessel performing steps of: maintaining a vacuum; heating the waste; returning a first portion of heated waste to the distillation vessel and a second-portion to mix with the waste feed; sending gaseous vapors to a condenser; returning some condensed liquid to the distillation vessel; and delivering condensed liquid as a product. The batch steps include: stopping waste flow into the distillation vessel; reducing pressure; heating the waste; returning the heated waste to the distillation vessel; condensing gaseous vapors; returning some condensed effluent to the distillation vessel; delivering some condensed effluent as a first product; and delivering heated waste as a second product.
