Abstract

See full text

Systems and methods are provided for reducing or minimizing fouling within the primary fractionator of a pyrolysis reaction system. The reduced or minimized fouling can be achieved in part by providing one or more pump-around trays in the primary fractionator below the level of the fractionation trays for an intermediate product produced by the fractionator. Including a pump-around section below the fractionation trays can improve vapor distribution within the fractionation trays, which are believed to have an increased likelihood of accumulation of foulant deposits. Optionally, other vapor distribution devices can be included along with the pump-around section.
