A combined vessel comprises a stripping section for removing acid gases from a sour water stream and a direct contact heat exchanger section for heating a graywater stream in order to improve heat and mass transfer in the treatment and recycle of water streams for a gasification process.

A method for storing solar energy and generating electric power comprising the steps of utilizing a solar powered water treatment device (2) to convert non-potable water (3) into distillate (4) and concentrate (5), storing the distillate and the concentrate in a distillate storage tank (104) and a concentrate storage tank (105) respectively and feeding the distillate from the distillate storage tank and the concentrate from the concentrate storage tank to a salient gradient power device (106) to generate electric power.

A multi-waste processing system includes a processing chamber. The processing chamber includes one or more heaters and a piston, and the processing chamber is configured to evaporate liquid waste and compact solid waste input. A condenser is operably connected to the processing chamber. The condenser is configured to condense water from the evaporated liquid waste output from the processing chamber. A gas and water separator is operably connected to the condenser. The gas and water separator is configured to separate water from the evaporated liquid waste output from the processing chamber. A recirculation pathway connects the gas and water separator to the processing chamber to recirculate gas from the gas and water separator to the processing chamber. The piston is actuated to keep the one or more heaters in close proximity to the solid waste and the liquid waste in the processing chamber.

A water sanitizing system is disclosed and includes an inner chamber and an outer chamber disposed at least partially around the inner chamber. A lens concentrates solar energy applied to a liquid within the inner chamber. A vacuum source in communication separately with the inner chamber and the outer chamber. The vacuum source controls a pressure within the inner chamber separately from the outer chamber for controlling conversion of liquid within the inner chamber to a gas. The outer chamber, also under vacuum, is an insulative layer to prevent heat loss.

This disclosure describes energy efficient process to distill a process stream in a production facility. A process uses multiple effect evaporators, ranging from one evaporator to eight evaporators in each effect. The process arrangement shows an example of four effect evaporators, with a zero-effect evaporator having a single evaporator, a first-effect evaporator having a set of three evaporators, a second-effect evaporator having a set of three evaporators, and a third-effect evaporator having a set of evaporators to create condensed distillers solubles.

A distillation system receives a feed solution to produce residue and distillate. A heat pump includes parts of a first and second heat exchangers, a working fluid, a working fluid compressor, and an expansion device. The working fluid receives available heat energy from the distillate in the second heat exchanger, receives at least some additional heat energy in the working fluid compressor, and releases at least some of that heat energy into the feed solution in the first heat exchanger. The first heat exchanger receives the feed solution, permitting transfer of at least some heat energy into it. A separator receives the feed solution from the first heat exchanger and separates it into the residue and distillate. The second heat exchanger receives the distillate, permitting transfer of at least some heat energy back into the working fluid. And a distillate extractor directs the distillate out of the second heat exchanger.

This invention provides methods for extracting ingredients and materials from plant material, including extracting ingredients from Cannabis plant material.

A method for separating and recovering compounds from biomass is provided. In the method, an aqueous extraction fluid in essentially gaseous phase, such as steam, is propagated through a reaction area containing biomass feedstock. When extraction fluid advances through the biomass feedstock, in predetermined reaction conditions, a target compound separates from the essentially solid feedstock matter and travels, with the extraction fluid, towards the end of the reaction area, in where the target compound is recovered in the form of an essentially liquid medium. The method is beneficial for extracting long-chain hemicelluloses from cellulose-containing feedstocks.
