Gravity Separation - an overview | ScienceDirect Topics

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

Gas Liquid Separation - EnggCyclopedia

Gas Liquid Separation. Gas liquid separation is often based on the principle of gravity settling, when liquid droplets suspended in rising gas vapors settle down at the bottom of the separation vessel and are eventually taken out through the bottom. Gas stream separated from liquid is taken out from the top of the separation vessel.

Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

THEORY AND OPERATION OF THE SPECIFIC GRAVITY …

The basic principle of operation of the gravity separator is that it takes ad-vantage of the difference in size, shape and specific gravity of particles. The actual separation takes place in two steps. The first is in the vertical direction by stratification of the seeds and the second is in the horizontal direction by the table motion and gravity.

This is important to the process of separation. instead of the bag filter, an oil flow diffuser may be used. This serves two purposes. First, it acts as a coalescer to enhance separation rate. Second, it functions as a flow diffuser to minimize tank turbulence. From this point, the oil/water mix begins gravity separation.
