Abstract:
Transportation of a waxy oil from a cold environment leads to a decrease in the solubility of paraffinic component and formation of a deposit on the pipe wall. The observation of the deposit structure helps to study hardening process. The study shows that deposit structure is changed from plate shape to mal-crystals and spherulites during its growth. Based on the result, the diffusivity of wax deposit participated in hardening process was modified.
