Inventor: KARLSEN MORTEN
IPC: C25C3/14
Filed: 2009-09-17
Abstract: An electrolysis cell producing metals needs to add an accurate amount of feed stock (like alumina) to the cell, and as an effect of the reaction taking place in the cell, one needs to extract the product (like aluminium) and remove any waste product (like HF and CO2). In order to cool the cell properly and to ensure collection of all the effluents from the cell, which is not gas tight, a normal suction is about 100-150 times more ambient air than gas volume produced by the cell. The present invention relates to the principles of how one can extract a more CO2- concentrated flue gas from the cell than is standard procedure in the aluminium industry today, by means of distributed pot suction (DPS) devices. In one embodiment the DPS can be integrated with a feeder having a breaker bar for feeding raw material to the cell. Heat energy can be extracted from the hot flue gas.

Filed: 2011-07-22
Abstract: A tank cleaning system used to clean sediment within large storage tanks, particularly crude oil tank bottoms, when the tanks are full by way of entering any of several valves located near the bottom of every tank. The cleaning system utilizes a large vacuum source delivered through a vacuum conduit containing internally a medium pressure hose with nozzle at the suction point delivering hot water downward to dislodge conglomerate sediment in tank bottoms for easy vacuuming to a vacuum truck. The guide box includes a sealing and bushing guiding arrangement to allow access to the tank with a vacuum conduit pipe without leakage to the ground. The guide box with self contained vacuum pipe sealing system and pressure equalizer system and leakage control system screws into the tank valve orifice and allows a vacuum conduit to penetrate the tanks remote bottom areas through the access valves raising cleaning efficiency dramatically and reducing cleaning events by up to 8 times. The guide box screwed into an access valve allows the operator to push and pull the vacuum conduit to engage the sediment in the bottom of the storage tank. The vacuum conduit is connected to a vacuum truck and is pushed in and out of the tank by the operator to affect the cleaning process.
