Use of hydrocyclones with a receiving bin for cleaning circulating water of mechanical impurities

Reduction in concentration of mechanical impurities is evaluated in the circulating flow of cleaned water, some of which has been passed through a hydrocyclone.A procedure for calculating the extent to which the solid phase is extracted into a slime-receiving bin is proposed for development of the hydrocyclone plant.

Gasoline production in stabilization of feedstock in hydrocyclones

Fundamentally new technology for production of gasoline in stabilization of crude oil and gas condensate in a centrifugal force field is directed toward increasing the intensity of the process and decreasing capital and power costs. By regulating the pressure and temperature at the inlet into the hydrocyclone, it is possible to control production of unstable gasoline. By-products of petrochemistry are used to increase its octane number. Synergism in improving the quality of the gasoline in multistage hydrocycloning of crude and incorporation of oxygen-containing components was demonstrated. __________ Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 1, pp. 6–9, January–February, 2006.     

水力旋流器的蜗壳设计理论与计算

水力旋流器蜗壳的作用是将直线运动液流变为圆周运动液流。从水力学观点出发,论证了蜗壳使液流流畅地进入旋流状态的条件,即转换过程水力损失要小,蜗壳曲线连接要光滑,不存拐点。根据上述要求,研究了阿基米德螺线、对数螺线及渐开线三种蜗壳曲线的水力损失,以及蜗壳曲线光滑连接的具体设计方法,用这些方法设计的蜗壳取得了良好效果。     

Stabilization of crude oil in hydrocyclones with treatment of casing-head gas to remove hydrogen sulfide

A method is proposed for stabilization of crude oil and condensate in hydrocyclones to create closed systems for exhaustive preparation of feedstock. Hydrocyclones are small, simple in layout, and highly efficient units that allow enhancing operation of the primary crude oil preparation system and equipping units in block-aggregate layout. Pilot-industrial tests of crude stabilization processes using centrifugal forces and preparation of gas to remove hydrogen sulfide demonstrate the possibility of industrial introduction of the new technology.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 1, pp. 12 – 15, January – February, 2005.
