Article Title: Studies on the Mechanism of Using Piezoelectric Energy to Control Wax Deposition
by Sulaiman, A. D and Ajienka, J. A

Wax deposition has long been a problem and expense in the production of oil. The three main reasons why waxy oils create problems in oil production are: restricted flow due to reduced inner diameter in pipelines and increased wall roughness, increased viscosity of the oil and settling of wax in storage tanks. With the advent of extremely deep production, offshore drilling and ocean flow completions, and indeed with the global concern on environmental damages due to oil activities, the use of preventive measures becomes probably the most economical. Therefore application of a simple tool that uses piezoelectric energy to prevent wax deposition is gaining popularity and patronage. This research work is aimed at developing a technique for studying the flow characteristics of crude oil at the temperature below the cloud point; examine the effect of piezoelectric energy generated from quartz plus semi-precious metals to these flow characteristics, and to correlate any changes in the flow characteristics with depositional changes. Crystal structure and charges distribution of the piezoelectric materials has been reviewed in this work. Properties of waxy crude oil samples, such as viscosity and wax appearance temperature, were measured before and after the use of the fabricated tool for treatment. The experiment demonstrated that the use of piezoelectric energy can have a measurable effect on properties of waxy crude oil. The study of crystal morphology also indicated that there are changes in the morphology of crystals of wax deposited after the treatment
