دانلود Three Years of Experience with Polyamines in the High Pressure Steam System of a Naphtha Cracker

Abstract

The design and operation of the high pressure steam system of a naphtha cracker pose specific problems which in some cases  cannot  be  satisfactorily  resolved  with  conventional  water/steam  treatment  programs.  Following  a  decade  of  operational experience with polyamine products at Iower pressures at the Geleen (petro)chemical site in the Netherlands, the ammonia/morpholine treatment of the 12.5 MPa steam system of one of SABIC Europe's naphtha crackers was converted a polyamine program in November 2005. In this paper, the characteristics of the cracker's steam system are first described. Particular  aspects  of  the  conversion  are  then  discussed.  Finally,  the  experience  gained  and  insights  obtained  into  the  polyamine treatment during the first three years are elaborated.
