Abstract
Methods for removing water and/or dissolved and solid contaminants from a liquid hydrocarbon such as condensate flowing through a fractionating column are disclosed. Pressure within the column and temperature at which the reboiler operates are observed to prevent boiling of the contaminated hydrocarbon thus obviating contaminant deposition on heated surfaces. Further methods directed to column operation and anti-fouling procedures augment the core method. Apparatus to effect the methods is also provided.
