Resumo
The use of dividing-wall columns for separating the C4+ pyrolysis fraction is considered. The influence of the phase state of the feed flow on the energy consumption in column reboilers is investigated. It is shown for the first time that the use of dividing-wall columns is more efficient when using the feed stream with a high vapor fraction of 80–100%. The largest energy-saving effect of the dividing-wall column is provided by using the feed in the vapor phase. In this case, the energy savings can reach 30%. In addition, it is shown that the use of dividing-wall columns reduces capital costs by 18–21%.
