  • Patent number: 10766789
    Abstract: A system for flue-gas hydrate-based desalination using LNG cold energy belongs to the field of hydrate technology application. The CO2 in the flue-gas is captured based on the hydrate formation. Two stage formation chambers are set to improve the hydrate formation. The two steps to purify the hydrates respectively are the gas separation and the liquid separation. The two methods of hydrate dissociation to realize the recycling of the waste heat of flue-gas and the CO2 are the heat-exchanged and the exhausted. The present invention realizes the integrated CO2 capture and seawater desalination with a proper structure and a subtle system and solves the cold energy source for hydrate-based desalination by means of using LNG cold energy. The two stage formation chambers solve the capture of CO2 in the flue-gas and guarantee the hydrate formation amounts. The two types of dissociation chambers decrease the heat emission by using the waste heat of flue-gas and realize the recycling and storage of CO2.

    Abstract: An oil conditioner is provided for removing impurities from oil, such as water, fuel and glycol, to increase engine life and efficiency. An evaporator assembly includes an upper plate, a lower plate, with a heater unit sandwiched between the two. To increase the efficiency of the evaporator assembly, materials are selected so that the upper plate thermal conductivity property is greater than the lower plate thermal conductivity property; and, optionally, the lower plate includes a reflective surface to direct thermal radiation toward the upper plate. This unique design enables oil conditioning with reduced power consumption and improved heating compared to existing technology.

  • Patent number: 10316394
    Abstract: The invention provides methods, compositions, and apparatuses for preventing the formation of scale in heap leach process solution distribution systems comprised of piping, spray nozzles, or emitter tubes. Solution distribution system components often become fouled by scale because of local hot spots more prone to form scale than other locations along the systems length. Positioning sensors that detect periods of high temperature stress and adjusting scale control reagent dosage to send the right amount to inhibit hot spot deposition allows for the control of scale without using wasteful excessive amounts of scale control reagents. This can vastly improve scale control performance under high temperature stress conditions while minimizing scale control reagent waste under less severe stress conditions to reduce the total operating cost of running heap leach mining operations which depend upon well-functioning solution distribution systems.

  • Patent number: 10286992
    Abstract: There is described a fluid treatment system that is particularly well suited for treating ballast water on a shipping vessel. The present fluid treatment system is characterized by having two general modes of operation. A so-called ballasting mode and a so-called deballasting mode. In the ballasting mode, water is pumped from the sea or other body of water in which the shipping vessel is located to a ballast fluid inlet in the present fluid treatment system. Thereafter, it passes through the filter separation and radiation treatment sections in the fluid treatment zone of the fluid treatment system. Next, the fluid exits the fluid outlet of the fluid treatment system and it is pumped to one or more ballast tanks that are located on the shipping vessel. In the deballasting mode, water contained in the ballast tank(s) is pumped to a deballasting fluid inlet of the fluid treatment system after which it is treated in the radiation section only—i.e.

  • Patent number: 10174495
    Abstract: A device for detecting the presence of hydrocarbon fluid in runoff water includes an outer canister and a cartridge situated within the outer canister. The cartridge includes a pre-filter, at least one containment vessel, a diffuser/separator member situated within the containment vessel, a hydrocarbon fluid accumulator and an electronic circuit. The diffuser/separator member slows the flow of runoff water entering the containment vessel so that oil in the runoff water separates from and rises to the surface of the water where it accumulates in the hydrocarbon fluid accumulator. A sensor situated in the hydrocarbon fluid accumulator detects the accumulated oil and sends a signal to the electronic circuit which, in turn, closes a valve and prevents water from flowing through an egress opening in the outer canister.

  • Publication number: 20130220939
    Abstract: The invention concerns a method of controlling addition rate of an odor control chemical to a wastewater line comprising means for adding odor control chemical to the wastewater. The method comprises measuring a level of dissolved sulfides in the wastewater line using a sulfide probe placed in said wastewater line, transferring data on the level of dissolved sulfides to a computing unit, determining a required odor control chemical addition rate in said computing unit based on said level of dissolved sulfides, and instructing the means for adding odor control chemical to add the odor control chemical at said required addition rate. The invention allows for accurate on-line control of the level of H2S in the wastewater line.

  • Patent number: 8518269
    Abstract: A low cost method and system for treating water, which will be used in an industrial process, is provided. A system of the invention generally includes at least one containing means, at least one coordination means, at least one chemical application means, at least one mobile suction means, and at least one filtration means. The coordination means can control the necessary processes depending on the system needs (e.g., water quality or purity). The method and system of the invention purifies the water and eliminates suspended solids without the need of filtering the totality of the water volume, but only filtering a small fraction of up to 200 times less than the flow filtered by a conventional water treatment filtration system.

  • Patent number: RE46219
    Abstract: A system for load control in an electrical power system is described, wherein one or more temperature-monitoring devices are provided to control operation of a pool pump. When ambient temperatures are relatively high, and thus, electrical power demands from air conditioning systems are relatively high, the temperature-monitoring devices can remove power from the controlled device during the hottest portions of the day. The temperature-monitoring devices can provide power to the controlled devices during the cooler portions of the day. During heat waves or other periods of relatively continuous high heat, the temperature-monitoring devices can schedule power to the controlled devices to reduce overall power demands and to run the controlled devices during the cooler portions of the day when air conditioning electrical loads are reduced. The temperature-monitoring devices can also coordinate operation of the pool pump and a pool heater.
