Water becomes a new oil. What is the most important need for all human beings? Of course survival is a clear answer. All of us need water to survive, but that is the main source of all life. For most of us, water is as useful as walking to the kitchen, but if this option no longer exists, water can be scarce and expensive. In fact, water is increasingly abused in fact, without precaution, and easily lost, and in the wrong hand it may be very expensive.
Vacuum and centrifuge: The oil can be pumped up with water and then the oil can be separated from the water using a centrifuge - the tanker can be filled with almost pure oil. Normally, water returns to the sea, making the process more efficient, but you can also reverse a small amount of oil. This problem interferes with the use of centrifuges because US regulations limit the amount of water returned to the sea. Use the Environmental Priority Index (ESI) map to identify sensitive shoreline resources prior to oil spills, to prioritize protection, and to plan purification strategies. By planning leak prevention in advance, we can minimize or prevent the environmental impact. The environment sensitivity index map basically consists of three types of information. Coastline type, biological and human resources.
Because water is an excellent medium for dispersion, emulsification and microbial decomposition processes, seawater runoff usually deteriorates rapidly. When released into the water, oil and petroleum products tend to accumulate on the water surface and float on the surface of the water. When small oil droplets are formed, surface contact with water and natural biodegradation of oil may increase. However, in order to prevent such vertical movement, this vertical movement can be delayed as long as no pavement surface, natural clay layer, or other natural or artificial obstructions are present. Oil may travel sideways along layers with low permeability (including surface pavement) or groundwater and surface water.
When oil spills into the sea, it diffuses initially into the water (mainly on the surface), depending on its relative density and composition. The formed oil film may be viscous or ruptured in a rough sea. Waves, streams and winds drifting oil to a wide area, affecting the oceans, coastal areas of the drifting path, and the sea and land habitats. Oils containing volatile organic compounds partially evaporate, lose 20% to 40% of their mass, become more dense and more viscous (ie more resistant to flow). A small amount of oil may dissolve in water. The oil residue is also dispersed in water almost invisibly, or forms a dense mousse with water. Part of the waste oil may suspend the particulate matter, the rest will eventually condense into a viscous tar ball.
