Ways of separating oil from water
Answers
Answer:
HOPE IT HELPS. BRO
Explanation:
You can use gravity oil separator (API separator) which sizing follows the "free sedimentation" law with the addition of a deformation coefficient of the oily particles.
The API (American Petroleum Institute) recommends the use of the following equation for the oil ascensional rate in m/h:
oil ascensional rate=0.443*(oil relative density - water relative density)/(water viscosity in poise)
The oil "particle" diameter is taken >= 0.15 mm and the water and oil density have to be preferably determined in laboratory.
The oil separator efficiency can be enhanced using PPI (parallel plate interceptor) with a slope of 45°.
The floated oil can be removed from the surface of the disoleator through a spillway.
Answer:
1)To separate oil from water, add a solution of soluble ionic salt to the solution. Distillation, which involves boiling and condensing the water, is another option, as well as partially freezing the oil and water combination and discarding one-fourth to one-third of the unfrozen water.
2)Changing the state of the water to either a gas or a solid is a means to cleanly remove all of the oil from the water.
3)Add some amount of copper sulphate(CuSO4) in the mixture. the water molecules get attracted to CuSO4 molecules and it will turn into blue colour.
4)Use Hierarchical membrane for Separating finely mixed oil and water
MIT researchers have discovered a new, inexpensive way of getting the two fluids apart again.
Their newly developed membrane could be manufactured at industrial scale, and could process large quantities of the finely mixed materials back into pure oil and water.
In addition to its possible role in cleaning up spills, the new method could also be used for routine drilling, such as in the deep ocean as well as on land, where water is injected into wells to help force oil out of deep rock formations.
