Hello All,
To recover Low moisture DMF from its Mother Liquor which contains DMF, Water, KCl and other impurities. here KCl and other impurities clog togather to become black sticky material. This sticky material is separated in 500 ltr capacity Tubular filters. the process of distillation is continous and under vacuum. when the filter get choked it is hard to remove the material from filter and its walls. materil forms roof in filter. How to deal with such sticy materil under cont. vacuum process???
