| titleOfInvention | Method and apparatus for producing pure formaldehyde |
| abstract | (57) [Summary] In particular, in a post-purification method of a pyrolysis gas for producing pure formaldehyde and using the same apparatus, hemiformal is pyrolyzed in an evaporator, and the resulting formaldehyde vapor is passed through the evaporator. The condensed liquid component collected in the bottom region is passed therethrough, and the condensed liquid component is positioned on its inner wall through a cooled outlet pipe located in the bottom region of the evaporator. And the formaldehyde vapor is passed co-currently through the cooling outlet tube, and the condensed liquid component and the formaldehyde are separately separated from the end of the outlet tube remote from the evaporator.
