In a spray drying apparatus, comprising in a usual manner a drying chamber, an air disperser, and at least one pressure nozzle arrangement (), means are provided for emptying the feed in the nozzle arrangement(s) () after the supply of feed from a feed system () is halted and before the nozzle arrangement(s) () are removed from the drying chamber and positioned in a cleaning system (). The emptying takes place while maintaining atomization in the nozzle arrangement (). The feed emptying system () comprises a pump (), a pressurized air/gas source () and a conduit (), and the spray drying apparatus at least one valve () allowing switching from the feed system () to the feed emptying system ().

A device and a process for producing high purity CO by electrolysis of CO2 in a Solid Oxide Electrolysis Cell stack and a gas separation unit, also the gas separation unit may be a Solid Oxide Electrolysis Cell stack.

Apparatus for production of high purity carbon monoxide

A cell stack comprising a plurality of fuel cells or electrolysis cells has a combination of flow patterns between anode gas and cathode gas internally in each of the cells and between the cells relative to each other such that cathode and anode gas internally in a cell flows in either co-flow, counter-flow or cross-flow and further that anode and cathode gas flow in one cell has co-flow, counter-flow or cross-flow relative to the anode and cathode gas flow in adjacent cells.

The invention provides an interconnect device for a fuel cell comprising an electrolyte, an anode and a cathode, the interconnect device comprising a channel system having a plurality of channels, each channel being closed in one end and having either an inlet side or an outlet side at the open end of the channel, each channel having an inlet side placed in alternating order with a channel having an outlet side, the inlet side of each channel placed in consecutive order on one side of the interconnect, and the outlet sides of each channel placed in consecutive order on the opposite side of the interconnect relative to the inlet side, and a second layer of channels is located on the surface of the channel system. The invention also provides a fuel cell and a fuel cell stack in which the interconnect device is used.
