The present disclosure relates to a process for treating a feedstock containing tall oil, the process including separation of a light stream from the feedstock, followed by removal of a heavy fraction from the feedstock, in which process the separation of the light stream from the feedstock a fractionator is used and at least one product is collected from the light stream. The disclosure also relates to an apparatus for use in the process and use of a fractionator in dehydration of a feedstock containing tall oil.

In order to prevent injury from hot exhaust gas, water is condensed by a metal net in the exhaust pipe.

A method of extracting an essential oil from plant matter, starting with providing plant matter to an interior of an extraction vessel, wherein the plant matter includes at least one essential oil. Next, at least one vacuum pump is used to reduce the pressure within the interior of the extraction vessel with the plant matter therein to an absolute pressure of less than 1.0 mm Hg absolute pressure. Microwave energy is applied to the plant matter while the interior of the extraction vessel is under the reduced pressure, thereby forming a vapor including at least a portion of the essential oil. The vapor is directed from the extraction vessel to at least one condenser vessel. Finally, the vapor is condensed to a liquid state such that the vapor includes at least a portion of the essential oil, by utilizing the at least one condenser vessel.

A mist extraction system is provided that includes a plenum box having an inlet configured to be coupled in fluid communication with a machine tool enclosure. A blower is coupled in fluid communication with the plenum box and is configured to draw air into the plenum box from the machine tool enclosure via the inlet of the plenum box and exhaust the air back into the machine tool enclosure via an outlet of the blower. A baffle plate is arranged in the plenum box to redirect the air drawn into the plenum box through the inlet of the plenum box and a filter panel is arranged in the plenum box to filter the air redirected by the baffle plate prior to the air entering the blower. A collector arranged to collect mist from the air condensed on the baffle plate and the filter panel.

The present invention relates to a method of preparing an aromatic vinyl compound-vinyl cyanide compound polymer including a step of separating volatile components from a polymerization product containing an aromatic vinyl compound-vinyl cyanide compound polymer, a residual aromatic vinyl monomer, a residual vinyl cyanide monomer, and an organic solvent using a volatilization tank, and a step of condensing the separated volatile components using a condenser, wherein an organic solvent or an aromatic vinyl monomer is sprayed onto the volatile components being transferred to the condenser. Volatile components may be fully condensed in a condenser, thereby significantly reducing the amount of volatile components discharged to the outside without being condensed. Therefore, wastewater treatment costs consumed in treating the volatile components may be reduced, and the amount of vinyl cyanide monomers harmful to the human body discharged into the atmosphere may be significantly reduced.

Provided are systems and related methods for processing organic polymeric feed materials—such as plastics—to form pyrolysis oil. The disclosed systems can be operated in a continuous manner and utilize novel liquid-solid separation techniques integrated with a novel condensing approach so as to operate in a product-efficient and an energy-efficient manner.

The disclosure provides methods and apparatus for producing 3-hydroxypropionic acid or a salt thereof, for removing 3-hydroxypropionic acid from aqueous solution (e.g., aqueous broth), and for using it to make various chemicals.

Provided herein are atmospheric water harvesting systems that are tailored with an optimal adsorption threshold, based on energy cost and water availability considerations. The systems include a plurality of adsorbent modules, each containing metal organic frameworks of various adsorption thresholds. Such a design enables real time adjustment to achieve optimal harvesting conditions in changing atmospheric conditions, whether for daily or seasonal humidity variations.

A thermal cracking treatment train, comprising: a rotatable kiln reactor; the rotatable kiln reactor being configured to receive a polymeric feed material, the reactor defining at least one interior wall that bounds an interior volume of the reactor, the interior volume defining an entrance and an exit along a direction of feed material travel, the rotatable kiln reactor comprising a section that comprises one or more sweeping features configured to sweep, with rotation of the kiln, a portion of the at least one interior wall, the kiln comprising a section that comprises one or more lifter features extending from the at least one interior wall and configured to, with rotation of the kiln, encourage material disposed on the one or more features to fall into the interior volume of the interior kiln; a combustor configured to provide a heated gas to the rotatable kiln reactor; and a devolatilization train.

Composite coatings that passively cool when exposed to the sky are provided. The composite coatings are suitable for increasing atmospheric condensation on a surface of a substrate. In particular, the composite coatings may be suitable for capturing atmospheric water. Also provided are methods for producing the composites coatings, methods for coating the surface of substrates with the composite coatings, methods for condensing and collecting atmospheric water, and systems for collecting condensed atmospheric water.
