The Effect of Magnetic Radiation on Pipeline Transportation of Crude Oil
The deposition of paraffin wax during the pipeline transportation impedes the flow of crude oil and eventually blocks the pipelines. The hot oiling method is extensively used to control the wax deposition in the oil industry. Consequently, a huge amount of energy is consumed to heat the crude oil by hot water or electrical power every year. In order to save the energy cost, the magnetic paraffin control technology is presented and evaluated with the hot oiling method, and accordingly the effect of the magnetic radiation on the oil transportation is detailed. The experiments carried out have demonstrated that the magnetic treatment can compensate for the resistance rising of the pipeline caused by the hot water reduction. Especially, the transportation of crude oil (at the surrounding temperature of -10°C~-30°C) without any heating has been observed in the Daqing oil field under the radiation of a magnetic field of 120 mT. In addition, the effect of the length of pipelines on the performance of magnetic treatment was also investigated.
Magnetic orientation of paraffin in a magnetic levitation furnace
Abstract Containerless melting of paraffin under a magnetic levitation condition has been performed by using a cryogen-free hybrid magnet and two kinds of laser furnaces. One is local irradiation of CO2 laser light at the top of the sample. The other is homogeneous irradiation of YAG laser light with a concave ring mirror. In the latter case, reduction of the Marangoni convection on the surface of the sample and the magnetic orientation of paraffin molecules were observed. The magnetic anisotropy of the spherical sample was confirmed by the measurement of magnetization and X-ray diffraction.
Containerless Melting of Glass by Magnetic Levitation Method
The Melting of glass materials levitated in high magnetic fields has been carried out without a crucible by using a hybrid magnet and a CO2 laser. A cubic glass with 6 mm sides has become a complete sphere through melting and cooling in the air. This new method will provide opportunities for obtaining high-purity and new heterogeneous materials.
