摘要： Process for producing para-xylene are described. The processes utilize a dual raffinate approach. Two raffinate streams from the adsorption separation unit are fed to the raffinate distillation column independently to take advantage of the differing desorbent concentrations in the two raffinate streams. The process yields significant reboiler duty savings and a reduction in overall fired fuel needed.

摘要： 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 %).

摘要： A device is provided having a fermentation chamber having one or more inlets to receive a mixed stream to be fermented and an outlet to release fermented product; a distillation vessel surrounding the fermentation chamber having communication with the fermentation chamber outlet to receive fermented product to be distilled and a turbine located within the outlet of the fermentation chamber, the turbine having a rotor rotatable by force of flow of fermented product from the fermentation chamber to the distillation vessel, to generate electricity. A sidewall common to both the fermentation chamber and distillation vessel allows for heat transfer of heat generated from fermentation to the distillation vessel to heat the product to be distilled. A method of fermenting and distilling a product is also provided. The method involves receiving in a fermentation chamber a mixed stream to be fermented; transferring heat energy generated by fermentation to a distillation vessel surrounding the fermentation chamber; allowing pressurized fermented product to flow from the fermentation chamber into the distillation vessel via a turbine and rotating a rotor of the turbine by a force of flow of the fermented product to the distiller to generate electricity.

摘要： The present invention relates to a system and method for desulfurization and denitrification integrated treatment and recycling of flue gas by using red mud, and belongs to the recycling and environmental protection technology field. The system includes a desulfurization spray tower, an ozone generator, a denitration spray tower, a slurry mixing tank, a slurry storage tank, a vacuum filter, an ammonia water neutralization tank, an aluminum hydroxide precipitation tank, an ammonia water tank, an aluminum hydroxide storage tank, a filter press, an ammonia distillation tower, a dephlegmator, a cooler, a concentrated ammonia water storage tank, a gypsum precipitation tank, and an anaerobic biochemical pool. In the present invention, red mud slurry is used for desulfurization and denitrification treatment of flue gas to remove SO2 and NO in the flue gas, so that SO2 and NO in the flue gas reach an emission standard.

摘要： The present invention concerns a method for purifying an aqueous lactic acid solution, obtained from a fermentation medium or from any other source previously cleared of solid substances and/or of biomass that may be present and ionic substances, characterised in that it comprises the two following steps: a. Concentration of the lactic acid solution until a concentration of between 85 and 95% is reached, preferably of between 90 and 95%, i.e. between 15 and 5% free water or preferably between 10 and 5% free water; b. Distillation in a multi-stage column comprising three areas and allowing the separation, in a single step, of the lactic acid, volatile compounds and the heaviest impurities.
