Self-heat recuperative dividing wall column for enhancing the energy efficiency of the reactive distillation process in the formic acid production process

摘要: Abstract This paper proposes a novel self-heat recuperative dividing wall column configuration to enhance energy efficiency of reactive distillation process in the formic acid production process. A patented as base case was optimized for further evaluation. Both external heat integration and thermal coupling were examined by placing side-reboiler onto configuring top column. finally proposed take synergistic advantage thermally-coupled heat-integrated structures. The requires no compressor provides preferable conditions recuperation avoiding remixing effect reducing requirements. can also be applied other similar processes improve efficiency.
