20100044217 | APPARATUS AND METHOD FOR THE REMOVAL OF GASSES - An apparatus for the removal of gasses from a number of electrolysis cells, including a suction duct for each cell, each suction duct being connected to a central manifold with a gas treatment centre and a central suction fan. A flow restriction device is provided in each suction duct. One or more additional ductworks are provided. Each additional ductwork is for one or more suction ducts. Each additional ductwork has a branch for each suction duct, the branch being connected to the suction duct between the electrolysis cell and the flow restriction device, which one or more branches are connected to a booster duct in which an on/off valve is present. One or more booster ducts are connected to a booster manifold connected to the central manifold. A booster fan is provided in the booster manifold. A method for performing an electrolysis process is also disclosed. | 02-25-2010 |
