Abstract
Wax crystallisation and deposition from offshore reservoirs have been causing serious problems such as plugged pipelines and reduced production flow rates. This issue is receiving more attention from the researchers and for commercial applications due to the shift in trend from using offshore production facilities to pipelines utilization. The aim of this study is the implementation of the Avrami theory to comprehend the mechanism of wax crystallisation to reveal the morphology of wax crystal using gravimetric and differential scanning calorimetry (DSC) analyses. The experiment values obtained from the Avrami’s theory for both gravimetric and DSC techniques shows that the crystals were one-dimensional with rod-like structures.
Farsi abstract
كريستاليزاسيون موم و رسوب از مخازن دريايي باعث مشكلات جدي مانند انسداد خطوط لوله و كاهش جريان توليد شده است. اين موضوع از توجه محققان و برنامه هاي تجاري به دليل تغيير روند استفاده از امكانات توليد دريايي به استفاده از خطوط لوله، بيشتر است. هدف از اين مطالعه پياده سازي تئوري آرومي براي درك مكانيسم بلورينگي موم است تا مورفولوژي كريستال موم را با استفاده از تجزيه و تحليل اسكن كالري سنجي (DSC) و جاذبه سنجي نشان دهد. مقادير آزمايشي حاصل از نظريه آرومي براي هر دو تكنيك جاذبه سنجي و DSC نشان مي دهد كه كريستال ها يك بعدي با ساختارهاي ميله اي مانند مي باشند.
