Its not needed. Just release the gas in the water and let it rise into the storage container. Remember acetic acid is water soluble, so it and the methanol end up in the water.
If you use an H cell and split water with sodium chloride as the electrolyte, keeping the electrode voltage at 13vdc or higher, the cell legs will bias to where the cathode side contains hydrogen and the anode side contains chlorine. This leaves a concentration of sodium hydroxide in the electrolyte. Use the concentrated electrolyte as the sealant water for the gas-o-meter.
(Of course the chlorine can be used to make sodium hypochlorite)
Some time ago I mentioned gasification of wood in a closed container, here I am attaching a sketch of my idea of it. At the top there would be a conically sealed opening for filling wood and emptying ash and a smaller pipe to release excess steam, at the bottom there would be welded pieces of steel for better heat transfer inside and retaining charcoal and wood. The gas outlet will be through a pipe that will also be a carrier and will be attached to the first wall of the furnace, which will open for filling and emptying the container, emptying will be done by removing the lid and overturning the container.
Are you vacuuming out the ash that is building up around the gas inlet and metal plates?
Is the concept, a better way to transfer heat into a retort vessel?
Bruce, this is just a sketch of an idea, otherwise I tried something years ago, but nothing serious. This project will also have to wait, but it is good to have theoretically clarified procedures and constructions.
In the drawing does the heat from the fire enter into the raw wood vessel though the open pipes at the bottom or are they metal heat sinks transfering heat through the bottom. The heat sinks will work. How will the vessel have the charcoal removed once it has been fully cooked?
Why not make the retort have a lid on top and remove the vessel that way. Open it reload it with wood and place it back into the retort to cook again. You just need the gas tube and vent come out the top.
This gives me a idea on how to improve on my retort for better charcoal cooking. Thanks.
