steam-assisted gravity drainage (sagd; "sag-d") is an enhanced oil recovery technology for producing heavy crude oil and bitumen.it is an advanced form of steam stimulation in which a pair of horizontal wells is drilled into the oil reservoir, one a few metres above the other.high pressure steam is continuously injected into the upper wellbore to …

Gravity separation - Wikipedia

The gravity separator separates products of same size but with difference in specific weight. It has a vibrating rectangular deck, which makes it easy for the product to tr kiavel a longer distance, ensuring improved quality of the end product. The pressurized air in the deck enables the material to split according to its specific weight.

Spiral separators, Gravity Separation | GSL

Spiral separators, or spirals for short, are a versatile method of gravity separation that can deal with a comparatively wide size range. Separation is achieved as a result of centrifugal forces induced by slurry running down the spiral, which forces lighter minerals to the outer bend whilst heavier minerals stay closer to the central axis of the spiral.
