I shuold clarify. I'm simulating an adsorbent bed for removal of H2 from the aforementioned mix of gases in aspen adsim (adsorption) and I need pre-exponential factors

Hi, I'm wondering if anyone knows where to find pre-exponential factors for gases... specifically, H2, CO, CH4, CO2, etc. Thanks

Hi, I'm wondering if anyone knows anything about shape factors. I've got an adsorption column (solid adsorbent in contact with a gas flow) and want to know what would give me a shape factor of 1? ex. beads, flat sheets, etc. Thanks.

Sorry, Canadian gov't. Thanks!

I'm wondering if anyone know where to find government regulations for production of chemicals - specifically pertaining to catalyst production in the range of a few tonnes. Any help would be appreciated Thanks

thx for your help!

I'm actually in Canada... so you wouldn't happen to know anything about canadian regulations? heh =T Thanks.

Does anyone know where I can find environmental regulations for allowable levels of CO2, CO, H2 and CH4 that can be put into the air? Thanks

Yes, the majority (70-90%) is syngas. Its partially reacted syngas which is to be recycled.

Sorry, completely forgot to add the units. Its in cubic meters per day. I've got a gas feed consisting of CO, H2, CH4, CO2 and C2H6 and i'm looking to separate out CO and H2 for a recycle loop in my process - although i'm more interested in the CO than the H2. The % of the components are...

It would be a gas stream of volumes in the range of say, 100,000-200,000 per day. I'm interested primarily in removing H2 and more importantly, CO from CO2 and CH4. THx

Hi, I'm wondering if anyone knows any companies/technologies that can separate Gases - specifically CO, CO2 and CH4. Thanks
