    Ethanol - Correction factor ?

    Thanks a lot for your input Guys, really interesting. Just FYI, my analyzer is a RAE Systems MiniRae3000. The Calibration Gas is Isobutylene. One can call up an extensive list of measured gases, the analyzer then applies a correction factor specific to the gas of interest. In my case...

    'Residence Time' in catalytic VOC removal

    George, thank you for your reply. The units are actual m3/hr, not Nm3/hr Regarding the catalyst block, the info I have from the 3rd party supplier is: Matl = Cordierite monolith Catalyst type = Platinum Cell Density = 200 cpsi (cells per inch2) Matrix = 150mmx 150mm x150mm Design Temp =...

    'Residence Time' in catalytic VOC removal

    What would normally be the design 'residence time' for gas flow through Platinum coated, ceramic honeycomb, catalyzer blocks ? My understanding is in order for the catalytic reaction to take place, the off-gas must reside in the catalyst bed for a certain length of time - I have heard time...

    Airbus A320 field landing

    Thanks @LittleInch The flight details seem strange - Sochi to Omsk, but they put the aircraft down just past Novosibirsk, c. 600km further east. (If I have the detail correct) Strange.

    Rubber to Metal Bonding - Substrate Preparation questions

    Max Hi Thanks once again for the information. Our components are comparatively small ( 10mm - 40mm diameter ) Brass and Aluminium are the most unpredictable, sometimes achieving good bond - then sometimes not. A further factor is that the local climate is hot and humid - c. 40oC in summer...
