Method And Apparatus For Cleaning A Petroleum Products Storage Tank

View page
US Patent:
50872940, Feb 11, 1992
Filed:
Apr 2, 1991
Appl. No.:
7/679445
Inventors:
Allen Rechtzigel - Inver Grove MN
International Classification:
B08B 302
B08B 9093
US Classification:
134 221
Abstract:
A method and device are provided for cleaning a storage tank for petroleum products of the type having a closed sidewall and a floating roof which floats upon the top of the petroleum products. Additionally, a plurality of downwardly depending legs are removably secured to the floating roof which engage the bottom of the storage tank when it is nearly empty thereby preventing the floating roof from contacting the bottom of the storage tank. The device includes an elongated nozzle having an upper end and a lower end with at least two spray jets adjacent its lower end. One of the legs is removed from the floating roof of the storage tank thereby forming an opening into which the nozzle is inserted so that its lower end is positioned adjacent the bottom of the storage tank. Thereafter, petroleum products under high pressure are pumped through the nozzle and thus through the spray jets. In doing so, the spray jets emulsify dirt, waxes, and other petroleum distillates which accumulate at the bottom of the tank.

US Patent:
48307467, May 16, 1989
Filed:
May 6, 1988
Appl. No.:
7/191151
Inventors:
Kenneth H. Liabenow - Livonia MI
Allen Rechtzigel - Inver Grove MN
Dennis Springer - Belleville MI
Assignee:
K & D Industries, Inc. - Romulus MI
International Classification:
B01D 3306
US Classification:
210202
Abstract:
An apparatus for continuously separating intermixed solids and liquids from industrial waste. The device includes an elongated conduit having an inlet and outlet and where the interior of the conduit forms a mixing chamber. The industrial waste is pumped into the inlet of the mixing chamber and a polyelectrolyte compound is introduced into the mixing chamber at at least two spaced locations along the conduit. The outlet of the conduit is then passed across both a stationary screen and then into a rotating drum separator, which, together, remove the water from the waste material.
