  • Injector for polymer placement and method therefore
    Patent number: 5741090
    Abstract: A system and method for injecting liquid/solid mixtures into porous pulse media, such as earth, is disclosed. A two-tank arrangement where liquid only is stored and run through a main pump, while a liquid/solid slurry is stored and moved to join the liquid under pressure by a chemical injector pump is shown. Finally, a displacement wheel commands solenoid valves, for pulsing the pressured liquid, through a distance measuring device such as a laser interacting with a laser target operatively coupled to a ground traveling wheel.
