Research results on the effects of magnetic fields on crude oil

The paper presents the results of the process of demulsification of crude oil, well No. 15 of the Supsa field. The reasons for the formation of persistent petroleum emulsion are considered, the component composition of crude oil is determined, including the content of the amount of formation water. The experiments were carried out at low (20-30)Hz and high (50-80) Hz frequencies of the magnetic field. The destruction of the oil-water emulsion was carried out without heat treatment under conditions of stabilization of the magnetic field and demulsifier Alkan 202. The technological scheme and parameters of crude oil dehydration are given. The influence of the magnetic field on the rate of destruction of the water-oil emulsion and the amount of released water is shown.

Review Analisis Teknologi Degradasi Limbah Minyak Bumi untuk Mengurangi Pencemaran Air Laut di Indonesia

Penentuan metode degradasi minyak bumi yang tepat sangat diperlukan untuk mengatasi pencemaran tumpahan minyak bumi khususnya di air laut Indonesia. Metode degradasi limbah minyak bumi yang digunakan adalah metode degradasi secara kimia dan biologi yaitu menggunakan surfaktan nonionik (Tween 80 dan Brij 35) dan bioremediasi menggunakan bakteri Pseudomonas aeruginosa.Variabel yang digunakan pada metode degradasi kimia dengan surfaktan nonionik adalah variasi konsentrasi 0.0000, 0.0025, 0.0050, 0.0075, 0.0100, 0.0125, 0.0150, 0.0175, 0.0200, 0.0225, 0.0250, 0.0275, 0.0300, 0.0350, 0.0400 % (v/v) dan variasi pengadukan untuk menguji stabilitas emulsi minyak bumi dengan laju 100, 120, dan 140 rpm selama 1 jam. Variabel yang digunakan pada metode bioremediasi adalah konsentrasi penambahan mikroba Pseudomonas aeruginosa sebanyak 0%; 1%; 3% (v/v), konsentrasi cemaran minyak bumi 1000 ppm dan 1500 ppm serta media aerasi dan media tanpa aerasi. Hasil degradasi minyak bumi terbaik didapatkan pada metode bioremeidasi menggunakan Pseudomonas aeruginosa dengan konsentrasi bakteri sebanyak 3% (v/v) pada media teraerasi dan konsentrasi cemaran minyak 1000 ppm dengan % biodegradasi TPH yang dicapai sebesar 100% dalam waktu 21 hari.ABSTRACTDetermination of appropriate petroleum degradation method is needed to overcome the contamination of oil spills, especially in Indonesia's seawater. The method of degradation of petroleum waste used is chemical and biological degradation method using nonionic surfactant (Tween 80 and Brij 35) and bioremediation using Pseudomonas aeruginosa bacteria. Variable used in chemical degradation method with nonionic surfactant is concentration variation 0.0000; 0.0025; 0.0050; 0.0075; 0.0100; 0.0125; 0.0150; 0.0175; 0.0200; 0.0225; 0.0250; 0.0275; 0.0300; 0.0350, 0.0400% (v / v) and stirring variations to test the stability of petroleum emulsion at rates 100, 120, and 140 rpm for 1 hour. The variable used in the bioremediation method is the concentration of Pseudomonas aeruginosa addition of 0%; 1%; 3% (v/v), the concentration of petroleum contamination 1000 ppm and 1500 ppm also aeration medium and aeration non medium. The best petroleum degradation results were obtained in bioremediation method using Pseudomonas aeruginosa with bacterial concentration of 3% (v / v) in aerated media and concentration of 1000 ppm oil contamination with TPH biodegradation achieved at 100% within 21 days.

Investigation on the Effect of Properties of the Filler on the Efficiency of the Separation of Water-Petroleum Emulsions

The aim of the present paper is to select suitable filtering material which would be effective for the separation of the aqueous petroleum emulsion. Furthermore, the paper discusses the principles and conditions for separation using filtering materials of different natures. During the experiments, the influences of several factors on the degree of separation were studied: 1) filler material 2) period of contact between emulsion and filler (by varying the model emulsion feeding rate and reactor size) 3) emulsion flow direction through the reactor (to study the effect of gravitation during separation). The experiments were performed with a cylindrical reactor. It was found that the effective separation of water and petroleum requires periods of contact between the emulsion and the filler. Besides, filler should have both hydrophilic and hydrophobic properties.
