ABSTRACT:
A method of feeding to a fractionator a feed mixture comprising a wide-boiling range vapor-liquid mixture is provided. Also, provided is a fractionator feed section adapted to receive a two phase feed mixture. Furthermore, this invention provides a fractionator that has operational stability when fed a feed mixture which generates significant volume of vapor in the feed section. A feed nozzle (112) may introduce a mixed liquid and gas feed downwardly between converging baffles (102,104) into a mixing zone (110) above a seal pan (106), and trough means (114,116) may introduce liquid reflux to the mixing zone.
