A system and method for cleaning dirty water is disclosed. The systems and methods may include two heat exchangers, including a high temperature/high pressure (HT/HP) heat exchanger that receives superheated steam and hydrogen gas and a low temperature/low pressure (LT/LP) that receives steam at a reduced temperature and pressure. The LT/LP heat exchanger provides first stage heating to dirty water that is input into the system for cleansing. The LT/LP heat exchanger has a first coil and a second coil. The first coil carries the dirty water to be cleaned. The HT/HP heat exchanger provides a second stage of heating to the dirty water that is output from the LT/LP heat exchanger. A first coil of the HT/HP heat exchanger carries the superheated steam and hydrogen gas. A second coil carries the preheated dirty water that is output from the LT/LP heat exchanger.

A method for recovering organic carbonates in an electrolytic solution of a waste lithium ion battery is provided. The organic carbonates include a first carbonate and a second carbonate having a higher melting point and a higher boiling point than the first carbonate. The method includes performing a temperature adjustment process in which an internal temperature of a drier in which the waste lithium ion battery is accommodated is kept in a first temperature range, an internal temperature of a pipe extending to below the drier is kept in a second temperature range, and an internal temperature of a condenser connected to the drier via the pipe is kept in a third temperature range, and performing a recovery process of reducing internal pressures of the drier, the pipe, and the condenser from a normal pressure to a first pressure and recovering the first carbonate in the condenser.

Systems and methods related to desalination systems are described herein. According to some embodiments, the desalination systems are hybrid systems comprising one or more first desalination units and one or more second desalination units. In some embodiments, the one or more second desalination units, which may form a fluidic circuit that is located downstream from the one or more first desalination units, may be configured to desalinate higher salinity liquid streams than the one or more first desalination units. In certain embodiments, the one or more first desalination units are operated under steady-state conditions and/or configured to operate under steady-state conditions. In certain embodiments, the one or more second desalination units are transiently operated and/or configured to facilitate transient operation. In some embodiments, a liquid stream comprising water and at least one dissolved salt is flowed through the one or more first desalination units, which are configured to remove at least a portion of the water from the liquid stream to form a first concentrated brine stream enriched in the dissolved salt. In some embodiments, at least a portion of the first concentrated brine stream is fed to a fluidic circuit comprising the one or more second desalination units. In some embodiments, the one or more second desalination units are configured to remove at least a portion of the water from the first concentrated brine stream to produce a second concentrated brine stream further enriched in the dissolved salt. In certain cases, the second concentrated brine stream is recirculated through at least a portion of the fluidic circuit until the second concentrated brine stream reaches a relatively high density (e.g., at least about 10 pounds per gallon) and/or a relatively high salinity (e.g., a total dissolved salt concentration of at least about 25 wt %).

An operations unit, comprising: a first chamber; a second chamber; a conduit extending through the first chamber and into the second chamber, the conduit being at least partially enclosed by a conduit jacket that defines an outer diameter, the conduit placing the second chamber into fluid communication with an environment exterior to the chamber, the second chamber comprising a wall facing the conduit jacket, and the second chamber being rotatable relative to the first chamber; a seal defining a boundary between the first chamber and the second chamber, the seal extending radially from the wall of the second chamber toward the conduit jacket, the seal comprising a flange, the flange defining an inner diameter, (a) the seal comprising a layered portion that comprises a plurality of ring-shaped portions, or (b) the seal comprising a brush that rotatably abuts the conduit jacket.

A low-temperature distillation facility for distilling a mixed fluid into a pure fluid. An aggregation device has an inlet connected to the vapour space of a supercooling chamber, wherein captured mixed fluid from an evaporator enters the supercooling chamber. The aggregation device's outlet is connected to the vapour space of a superheating chamber, wherein captured pure fluid from a condenser can be sprayed into the superheating chamber. An energy source cools the temperature in the supercooling chamber and heats the temperature in the superheating chamber. A heat exchanger is arranged between the exits of the supercooling chamber and of the superheating chamber. During the process, vapour flows from the supercooling chamber via the aggregation device to the superheating chamber.

A device for recovery of the atmosphere containing solvent vapors from at least one ink recovery reservoir of a print machine comprising: n (n1) filter(s) arranged at the outlet from at least one ink reservoir (10). Each filter comprises an inlet face, an outlet face, a filter body between the two faces, and conduit(s) for recovering at least part of a liquid condensed on the surface of the inlet face before this liquid has passed through it. Each filter is either: upstream from a condenser, an atmosphere output from the reservoir, passing through the inlet face, and then the filter body and the outlet face before being sent to the condenser; or downstream from the condenser, an atmosphere from the condenser passing through the inlet face, and then the filter body and the outlet face before being sent to at least one print head of the print machine, respectively.
