چکیده

انتقال نفت واکس دار از نقاط سرد سبب کاهش حلالیت ترکیبات پارافینی در نفت و رسوب آنها بر دیواره لوله می‌شود. با بررسی ساختار رسوب، می‌ توان فرایند سخت شدن رسوب را بررسی نمود. بررسی ساختار رسوب در لوله نشان دادکه بلورها با رشد لایه رسوب، از ساختار صفحه‌ای به ناقص و گویچه‌ای تغییر شکل می‌یابد. با مشاهده ‌های انجام شده نسبت ابعادی بلورها در معادله پیش بینی نفوذپذیری رسوب تصحیح شد.
