  • Patent number: 10934177
    Abstract: Various embodiments may include a system for removing contaminants from contaminated water comprising: a distillation still supplying heat to contaminated water to boil the contaminated water; a vent allowing a vapor stream to exit the distillation still; an oxidation unit removing additional contaminants from the vapor stream; an outlet discharging a purified water stream from the oxidation unit; and a heat exchanger transferring heat from the purified water stream leaving the oxidation unit to the vapor stream exiting the distillation still before the vapor stream enters the oxidation unit.
    Type: Grant
    Filed: November 7, 2019

  • Patent number: 10472259
    Abstract: The present disclosure relates to water purification. The teachings thereof may be embodied in processes for removing contaminants from contaminated water. An example process may include: boiling or evaporating a contaminated water to distill the contaminated water; removing a vapor stream from the boiling or evaporating contaminated water; delivering the vapor stream to an oxidation unit; removing additional contaminants from the vapor stream in the oxidation unit; and discharging a purified water stream from the oxidation unit.

  • Patent number: 9856391
    Abstract: A process for preparing a starch dispersion may include combining a feed starch and an aqueous liquid to form a starch slurry. The starch slurry may be subjected to a first degradation treatment to form a first mixture. A temperature of the starch slurry during the first degradation treatment may be less than a gelation temperature. The first mixture may be heated to a temperature between the gelation temperature and a solubilization temperature. The heated first mixture may be subjected to a second degradation treatment to form a second mixture. The second mixture may be sheared to form the starch dispersion.

  • Publication number: 20080256767
    Abstract: The present invention provides a portable shippable morgue system. The system may comprise (1) bottom, top and corner rails, and (2) corner fittings. Corner rails extend between bottom and top rails and connect them together to form a square and/or rectangular shaped frame. Bottom rails may include forklift engagement areas. Corner fittings are located at the connection point of the vertical corner rails and top rails. A top is positioned between the top rails and a bottom is positioned between the bottom rails. Vertically opposed end walls may be positioned between the top and bottom rails. The invention provides first and second spaced apart opposed vertical platforms, each in abutting engagement or engageable with a top rail and a bottom rail. The invention further provides a remains storage unit.
