20150203377 | SYSTEM FOR REMOVING MINERALS FROM A BRINE USING ELECTRODIALYSIS - A system for removing minerals from a brine using electrodialysis. One system includes a gypsum removal system configured to receive a feed stream having a first amount of gypsum, to extract at least a portion of the gypsum from the feed stream, and to produce a first output having a second amount of the gypsum less than the first amount of the gypsum. The system also includes an electrodialysis (ED) system fluidly coupled to the gypsum removal system and configured to receive the first output from the gypsum removal system, to produce a second output having a substantially sulfate hardness free sodium sulfate solution, to produce a third output having a sodium chloride solution, and to produce a fourth output having a mineral solution. | 07-23-2015 |
20140319040 | HYDROCHLORIC ACID PRODUCTION SYSTEM - A system includes an ion separation unit that may receive dilute hydrochloric acid and may generate a concentrated hydrochloric acid and a chamber fluidly coupled to the ion separation unit. The chamber may receive the concentrated hydrochloric acid and may separate the concentrated hydrochloric acid into a liquid concentrated hydrochloric acid and a vapor containing vaporized hydrochloric acid. The system also includes a scrubber fluidly coupled to the chamber. The scrubber may receive the vapor from the chamber, and the scrubber is may remove at least a portion of the vaporized hydrochloric acid from the vapor via a purified condensate to generate a purified vapor and the dilute hydrochloric acid. The system also includes a condenser fluidly coupled to the scrubber The condenser may receive the purified vapor from the scrubber to condense the purified vapor into the purified condensate, and to output the purified condensate to the scrubber. | 10-30-2014 |
20140045248 | SYSTEM FOR REMOVING SELENIUM FROM A FEED STREAM - A system for removing selenium from a solid feed stream includes a selenium dissolver configured to selectively dissolve elemental selenium from the solid feed stream and to produce a selenium rich solution and a crystallizer coupled to the selenium dissolver and configured to receive the selenium rich solution from the dissolver, to add an acid to the selenium rich solution, to remove purified selenium from the selenium rich solution, and to remove sulfur dioxide from the selenium rich solution. | 02-13-2014 |
20140044485 | SYSTEM FOR PRODUCING A GYPSUM SLURRY FOR IRRIGATION - A system includes a conveyor providing an agricultural grade gypsum, a pump providing a fluid, a mixing device configured to mix the agricultural grade gypsum provided by the conveyor with the fluid provided by the pump to produce a gypsum slurry, and a slurry pump configured to pump the gypsum slurry from the mixing device to a storage tank. | 02-13-2014 |
20140042061 | HEATING SYSTEM FOR DESALINATION - A heating system for desalination. One system includes a desalination system configured to receive a brine and to produce desalinated water from the brine. The system also includes a power production system having an engine configured to provide power to the desalination system. The power production system does not include combined cycle power production. The system also includes a heating system driven by the power production system and configured to provide heat for heating the brine. | 02-13-2014 |
20140042029 | SYSTEM FOR RINSING ELECTRODIALYSIS ELECTRODES - A system for rinsing electrodialysis electrodes includes an anode input coupled to an anode of an electrodialysis (ED) system for receiving a first fluid from the anode. The first fluid is for removing ions from the anode. The system also includes an anode output coupled to the anode of the ED system for providing the first fluid to the anode. The system includes a cathode input coupled to a cathode of the ED system for receiving a second fluid from the cathode. The second fluid is for removing ions from the cathode of the ED system. The system also includes a cathode output coupled to the cathode of the ED system for providing the second fluid to the cathode. The system includes an air stripper for receiving the first and/or second fluid, and for removing oxygen and/or a chlorine gas from the first and/or second fluid. | 02-13-2014 |
20140041810 | SYSTEM FOR REMOVING HIGH PURITY SALT FROM A BRINE - A system for removing high purity salt from a brine. One system includes a first evaporator configured to receive a brine stream, to produce a first output comprising a sodium chloride slurry, and to produce a first intermediate output. The system also includes a second evaporator fluidly coupled to the first evaporator and configured to receive the first intermediate output, to produce a first recovery output, and to produce a second intermediate output. The system includes a third evaporator fluidly coupled to the second evaporator and configured to receive the second intermediate output and to produce a second recovery output. The first recovery output and the second recovery output are used to produce the brine stream received by the first evaporator. | 02-13-2014 |
