Abstract: The fractionation technique using high temperature and positive pressure is adopted in stabili-zing condensate oil from the Dalaoba Uas Condensate Field.Packed column is chosen to condense andstabilize oil.The reboiler is of siphonage structure.The operating temperature at the bottom of the to-lumn is 195 0C.Salt content of condensate oil entering the column amounts to 963 mg/I.“Salt precipita-tion" may cause blocks and erosions in the column and the reboiler tubes,seriously affecting productStablllty.In thlS papeY,the processing technique,operating parameter and preservation of stabilizingsystem for condensate oil were studied and improved.Several fruits were gained.
