D-110 is a skid-mounted Butadiene Distillation column, i.e. feed liquid added to the 8th tray (numbered from the bottom) of the column plus reflux liquid added to the 16th (top tray of the column) cascade over each of 16 perforated tray decks, condensing components having high boiling points (e.g. 4-VCH and various additives), while allowing low boiling point components (e.g. Butadiene) to flow to the top of the column as vapor. Over the 16 trays, 4-VCH is effectively removed from the butadiene so that the overhead streams in the system are free of 4-VCH and the bottom streams have concentrated 4-VCH and other high boilers with a reduced amount of butadiene. Measurement of 4-VCH is by manual sampling and off-skid laboratory analysis.
