The aim of the research work is the development of technology for obtaining substances that reduce the viscosity of heavy oils based on the cotton phosphatide concentrate and soapstock, as well as their use in combination with EMO in the latter and their use in transporting the latter through pipelines.
The scientific novelty of research:
the chemical composition and colloid-chemical properties of local heavy oils are determined, which determine their high viscosity and low fluidity;
structural and rheological properties of local heavy Dzharkurgan, Mingbulak and other oil fields and their influence on the quality of the oil mixtures produced are determined;
created scientifically-based methods for obtaining ionogenic and non-ionic surfactants from phosphatide concentrate, cotton soapstock;
created effective compositions based on the obtained substances to reduce the viscosity of heavy oils;
the introduction of the proposed surfactant composition has been shown to have depressor activity on highly paraffinic oils, transferring refractory paraffins from solid state to liquid where new oil system is formed that solidifies at lower temperatures;
the positive influence of local heavy oil (with magnetic field strength equal to 1000-2500 oersteds) on the viscosity decrease and increase of their fluidity is proved.
combined method for lowering the viscosity of heavy oil and optimal technological mode, through the joint use of EMO, and the created SAA compositions.
