18 rows·Suggested Citation:2 Chemical and Physical Properties of Crude Oils. National results for this questionHow are chemical dispersants used?How are chemical dispersants used?Chemical dispersants are used only at depths of more than 60 metres.They break up the oil into droplets that are rapidly diluted by turbulent waves.Adding chemical dispersants speeds up the process of natural dispersion and in dispersed form,the oil is easily degraded by microorganisms.Explaining the chemistry of an oil spill - Down to Earth

The Physical,Chemical,and Biological Effects of Crude

large-scale extraction and transport of crude oil overland through that pipeline led to the possibility of crude oil spills on terrestrial ecosystems in cold regions.Research was initiated in the early 1970s to determine the effects of oil spills on vegetation,hydrology,and the physical,chemical,and biological properties of soil in taiga The evaporation of oil spillsphysical properties.Introduction .Evaporation is a very important process for most oil spills.In a few days,light crude oils can be reduced by up to 75% oftheir initial volume and medium crudes up to 40% oftheir volume.Heavy or residual oils will only lose about 5% oftheir volume in the first few days following a spill.Types of Oil Emergency Response US EPACharacterization of crude oils and refined petroleum products in a release situation is one of the earliest response tasks that must be undertaken.Proper classification and an understanding of the chemical and physical properties of these substances helps determine The hazard to personnel and wildlife;
