Pre-commissioning:

Fuel Cell Catalyst Process

2007

 

 

 

Project Background

End Client: Ceramic Fuel Cells Limited, Bromborough

The pre-commissioning work was undertaken for Thermal Transfer Limited (TTL) who installed this semi-production scale facility for CFCL to produce high value catalyst for use in domestic fuel cells. The state of the art technology is proprietary to CFCL, who carried out the final commissioning with reagents.

 

 

Summary of Process

 

Pre-weighed amounts of reagents are charged in to two tanks containing measured amounts of nuclear grade de-ionised water. One tank is charged by gravity from a high level sack tip station. The other is charged using an aero-mechanical conveyor from a ground level sack tip station. Mixers in the tanks ensure homogenous distribution of the material. One of the tanks is electrically heated.

Once prepared, the solutions are transferred to a buffer tank using air driven diaphragm pumps.

Gear pumps feed the solutions at controlled rates from the buffer tanks to a reactor and the reaction products discharge to a holding vessel. A plate heat exchanger provides cooling for one of the feed streams.

All the tanks are connected to an emissions control scrubber and induced draft fans.

The material from this vessel undergoes further proprietary processing to produce high purity nano-powders.

The process is PLC controlled from a local HMI panel.
