  • Publication number: 20230235232
    Abstract: A method of hydrocarbon reclamation utilizing an automated, closed-loop hydrocarbon reclamation system controlled by an operating system. Hydrocarbon is removed from hydrocarbon-fouled substrate by flowing a slurry through a series of chemical and mechanical processes and selectively recycling fluid throughout the system for continuous operation.

  • Patent number: 9433908
    Abstract: Rapid evacuation and deployment of dry materials is achieved by the dual structure of this device and the method of using it to fill and empty vacuum reloading tanks automatically. This permits materials such a bentonite, barite or cement to be handled easily and without dust on a rig floor and mixed appropriately as needed for well control and completion operations. Dry bulk material is offloaded from an offshore supply vessel into atmospheric tanks, which provide fluidized bed systems to aerate and agitate and move material through piping into the vacuum re-loader tanks. The dual re-loader tank system allows one tank to be emptied while another fills thereby providing sufficient flexibility to expertly manage receiving, storage, transfer, filtration and control of the bulk material on various space-critical platforms, including offshore rigs and service vessels, that require the handling of dry bulk materials in an accurate and dust-free manner.

  • Patent number: 9242260
    Abstract: A directed multiport jetting nozzle in an eductor having a focal point of the motive fluid inside the throat of a venturi-diffuser body of the present eductor provides an efficient pump and mixer providing substantial surface contact area between the motive flow and the bulk material for movement through the outlet of the eductor. The result of this design provides a homogeneous mixture of the motive fluid and the bulk material which may be hydrating or wetting, or the creation of a slurry.

  • Publication number: 20150151998
    Abstract: A water reclamation system is composed of a high-capacity input pump connected to an ionizer, which dissociates solid or biological particles from the water. After leaving the ionizer, the fluid stream is run through staged filter systems progressively filtering the solids from the water, which is then fed to a reverse osmosis system for further filtration. Rejected water is diverted to a series of thermal units which cause the rejected water to flash into steam which is returned to the cleaned water stream of the reverse osmosis unit for discharge or further use; the remaining water, having the remaining solids and biological materials, is sent to a fracture unit where it is incinerated at an elevated temperature. The system is designed to provide parallel backups at each part of the process allowing cleaning to take place continuously while the other parallel system is operating.

  • Publication number: 20140042060
    Abstract: A method for removal of hydrocarbons from solid particulate matter provides a chemical treatment which moves particulate matter combined with a water and chemical mixture which is moved progressively through separation tanks to remove the particulate matter from the hydrocarbons after coating and allow the hydrocarbons to float free from the particulate substrate. The removal apparatus consists of a series of tanks through which the coated and fouled solid material is moved to progressively remove hydrocarbons from the surface of the solid material leaving the solids in one stream and the hydrocarbons in a second stream for disposal or further use.

  • Publication number: 20110017584
    Abstract: A system for desalinating water includes a generally cylindrical enclosure (10) and a vacuum generator (46) for forming a partial vacuum within the enclosure. Eductor (24) within a lower end of the enclosure receives heated air and brine water, and outputs a mixture of heated air and water vapor and droplets into the enclosure. Condensate collector (34) is positioned above the eductor for collecting desalinated condensate, and heat exchanger (18) above the condensate collector transfers heat within the enclosure to the brine water and condenses the water vapor to desalinated condensate.
