In petroleum chemistry, waxy oil from paraffins can cause operating problems for production. The chemical method is used to remove by using chemicals or additives prevent the wax problem. this study, performance of inhibitor are evaluated measurement pour-point reduction and deposition crude Mae Soon area, Fang oilfield. Wax determined cold finger technique. inhibitors, hexane, Poly(maleic anhy...

We explore some rheological aspects of the yielding gelled waxy crude oil on basis a fractal model for structural description gel and Marrucci’s time evolution stress with mixed elastic viscous effects. With parameters directly obtained from classic rheometry, others by fitting to experimental data one shear-rate condition, flow curves another condition are predicted. Both theoretical curves—th...

Transportation of waxy crude oil in a production pipeline often encountered flow assurance issues, such as wax deposition. In case where shutdown is needed, deposit likely to form within the pipelines, which leads operational complexity during restart phase. Commonly, restarts after significantly high pressure pumped longer than necessary. This due physical hindrance caused by solid wax, requir...

Accurately obtaining the temperature distribution of medium in shutdown pipe-line waxy crude-oil has important guiding significance for making maintenance plan and restart plan. The phase transition process involves complex problems such as natural-convection heat transfer, latent release, difficulty tracing liquid-solid interface. In this paper, concept breaking point were proposed. Taking fre...
