Patent number: 8721166Abstract: A method of evacuating a refinery tank containing waste with solid constituents is disclosed. The method includes inserting an agitator on a boom through a first opening on a side of the refinery tank and agitating waste in a first area of the refinery tank to cause the waste in the first area to have a first viscosity lower than a second viscosity of waste in a second area at a periphery of the first area. The method further includes removing agitated waste from the first area while maintaining the waste of the second viscosity in the second area, thereby forming a safe room in the refinery tank. The method also includes expanding the first opening toward the floor of the safe room to enable entry of a movable excavator into the safe room of the refinery tank and removing waste of the second viscosity from the second area of the refinery tank.Type: GrantFiled: January 14, 2014Date of Patent: May 13, 2014Assignee: The Maitland CompanyInventor: Robert M.

Patent number: 6641297Abstract: An apparatus for holding hazardous waste made up of solids and liquids in a flowable form includes a tank made of material selected to be impervious to and non-corrodible by the hazardous waste and having a non-critical portion, an agitator in the tank having fluid agitation portions oriented for rotational movement about a horizontal axis, a non-sparking motor located within the tank connected to the agitator for imparting rotation to the fluid agitation portions, and a power source for the motor outside the tank having means passing through the non-critical portion of the tank for communicating power from the power source to the motor. Thus, the power source may communicate power to the non-spark generating motor to impart rotation to the agitator to cause the fluid agitation portions to agitate hazardous waste made up of solids and liquids held in the tank to maintain the hazardous waste in flowable form.Type: GrantFiled: November 5, 2001Date of Patent: November 4, 2003Inventor: Robert M. Rumph
