Yep. I proved that concept outside to make sure no one became internet famous around here.
We have a small boiler that backfired one day and it also has giving me a new found respect for maintenance on all equipment and proper procedures.
Heat guns are necessary for us, but only when used correctly. We may look at some more stringent rules when it comes to heat guns, though we are very safe already.
We dry our spent biomass in a giant paddle dryer and recover the EtOH. We start with 190proof, the recovered EtOH is 150-160 and smells like silage. We did some distillation experiments to see if we could redistill and lose the smell. We did get up to 190 pretty easily but the smell persisted. Perhaps carbon filtering would help the smell, but my bench-top experiments haven’t been encouraging. We will continue drying because its much safer than transporting EtOH laden spent biomass, but I’m more and more skeptical that recovery will ever equal cash.
No its illegal unless you have a license to manufacture it.
Do you know the auto-ignition temp of your solvent?
Is there O2 in the container?
You sure the container is sealed?!?
Heat guns are great tools, they are not always the right tool.
