  • Publication number: 20150010357
    Abstract: A method and arrangement are proposed for injecting CO2 into a subterranean aquifer for storage therein. In order to reduce the effects of water evaporation from brine in the aquifer when dry CO2 is injected into the aquifer, the CO2 is supplied mixed with a salt-lean fluid, i.e. a fluid that contains a low concentration of ions that can precipitate out as salts. The mixing may take place at the wellhead, with the CO2 salt-lean fluids supplied via separate low-grade material pipelines. The proportion of CO2 and salt-lean fluid in the mixture is such as to obtain a CO2 composition that is saturated with salt-lean fluid at the site of injection into the aquifer. By injecting saturated or “wet” CO2, less water is evaporated from the brine and the salt precipitation is greatly reduced, so keeping the pore spaces clear and providing an increased accessible pore volume for CO2 storage.

    Abstract: A distribution system and method for simultaneously distributing and reclaiming a liquid with a single, multi-directional system pathway. The system pathway follows a circuitous path for both receiving liquid from and returning reclaimed liquid to a reservoir positioned beneath a ground surface. A distribution pathway, such as a pipe, may carry the liquid with pressure from the reservoir to a distribution outlet. A reclamation pathway, such as a perforated pipe, may encapsulate the distribution pathway, and capture runoff and excessive liquid through at least one aperture for returning the liquid back to the reservoir. In some embodiments, the system pathway may include one perforated pipe that forms a barrier between the distribution pathway and the reclamation pathway. A film may cover the perforations to allow for pressurizing the water. A system of pumps, valves, and a control apparatus help regulate the liquid.

  • Patent number: 8657528
    Abstract: Brine disposal systems are configured to receive brine from a brine source and to passively collect seawater from a nearby ocean during high tide using one or more tidal forces. Tidal movements during high tide, low tide, or both may be used to mix and thereby dilute the brine with the seawater. The mixture of seawater and brine is then passively discharged into the ocean during low tide using the tidal force, thereby minimizing the impacts on the marine ecosystem.

  • Patent number: 8561633
    Abstract: The steel-reinforced HDPE rain harvesting system collects, stores, and pumps harvested rain water for a variety of non-portable uses. The rain harvesting system includes either a horizontally disposed or vertically disposed steel-reinforced plastic cylindrical wetwell connected to an inlet pipe. The inlet pipe discharges rain water into a rain filter made from a pervious concrete manhole lined with a replaceable 20-micron filter cloth. The rain filter allows rain water into the storage section of the wetwell. A high water alarm is disposed in the rain filter and alerts maintenance personnel to clean the filter when needed. A submersible pump is housed in an HDPE pump sleeve outside the wetwell and conveys effluent from a forcemain at the wetwell's bottom portion to a target area. A level monitoring system disposed inside the wetwell selectively activates the pumping system. Maintenance hatches atop the unit are included.

  • Publication number: 20130156502
    Abstract: A method and system for storing and supplying hydrogen to a hydrogen pipeline in which a compressed hydrogen feed stream is introduced into a salt cavern for storage and a stored hydrogen stream is retrieved from the salt cavern and reintroduced into the hydrogen pipeline. A minimum quantity of stored hydrogen is maintained in the salt cavern to produce a stagnant layer having a carbon dioxide content along the cavern wall and the top of a residual brine layer located within the salt cavern. The compressed hydrogen feed stream is introduced into the salt cavern and the stored hydrogen stream is withdrawn without disturbing the stagnant layer to prevent carbon dioxide contamination from being drawn into the stored hydrogen stream being reintroduced into the hydrogen pipeline. This allows the stored hydrogen stream to be reintroduced into the hydrogen pipeline without carbon dioxide removal.
