Management of Research Experiments

The laboratory bench area was covered by a large hood connected to a third exhaust fan so that experimentally generated flammable gas from open rigs was vented separately out of the laboratory. 

The fan exits through the roof had to be positioned away from the edges so as to reduce the likelihood of a lightning strike during a thunderstorm. 

An additional multi-point access vent line, positioned all round the laboratory and exhausting into the fan entrance was used to take boil-off gas from experiments and storage vessels. 

These arrangements enabled liquid methane, LNG and liquefied ethane, propane and butane to be handled in both open-top and closed dewars, cryostats and containers, just like LIN. 

In this way, students were able to gain hands-on experience, and meet at first hand the limits of measurement with instrumentation, caused by some of the peculiar properties of LNG, with its foaming, spitting and Marangoni wall films.
