The experimental study of increasing the efficiency of emulsion separation

Abstract

The aim of this research paper is to compare the operation efficiency of two types of coalescents: insert, made of high porous material and flat baffles. For this purpose, the method of physical experiment was applied. This research paper shows that the use of them in the settling tank allows to increase the efficiency and velocity of water-oil emulsion separation with an increase of oil concentration in the original mixture from 15 up to 25%. The experimental studies also show that the most effective coalescers are the baffles, than the inserts, made of highly porous cellular material, due to the fact that the cells are quickly clogged with heavy oil components, which leads to a more complex flow structure through them, therefore, the process of mixing oil and water compounds is intensified and prevails over the coalescence process. The velocity of oil-water emulsion separation when using the inserts, made of highly porous cellular material, and baffles in comparison with the settling tank without inserts, increases on average by 10.9 and 14.5%.

Effect of arc element diameter on fine particle collection efficiency of the separator

“…The diameter of the arc elements is relatively small, so the turning radius of the gas is also small. This results in high centrifugal forces that act on solid particles in the flow during moving dusty flow [10][11][12][13]. In addition, the particles are affected by gravity.…”
