What are oil spills hazards?
Summary of Potential Hazards to Deepwater Horizon Response Workers
| Potential Hazard | Risk Assessment |
|---|---|
| Cardiovascular Disease | Pre-placement physical: BMI*, BP, pulse |
| Heat Stress | Temperature, humidity, work load |
| Traumatic Incident Stress | Mental and emotional health |
| Fatigue | Work hours and schedules |
What is the meaning of sorbents?
A sorbent is a material used to absorb or adsorb liquids or gases. Examples include: A material similar to molecular sieve material, which acts by adsorption (attracting molecules to its surface). It has a large internal surface area and good thermal conductivity.
Are sorbents reusable?
Sorbents are reusable at least ten times. They are suitable for oil spill event at harsh conditions.
How are dispersants used in oil spills?
Dispersants are chemicals that are sprayed on a surface oil slick to break down the oil into smaller droplets that more readily mix with the water. Dispersants do not reduce the amount of oil entering the environment, but push the effects of the spill underwater.
What are the advantages of sorbents?
An advantage of sorbents is that hydrogen remains in its molecular form with a small activation energy rather than the atomic form in absorption. However, adsorption enthalpies are much lower than absorption ones that is a main disadvantage of sorbents in hydrogen storage.
How do oil spills affect the economy?
Economic impacts of oil spills generally include cost of clean-up and compensation, damage to agricultural lands, fishery and wildlife. Social impact on the other hand includes community conflicts, violence and frustration which leads to militancy, reduction in tourism and hospitality industries.
How does an oil spill happen?
How Do Oil Spill Happen? Oil spills take place when there is failure of the oil drilling machinery, due to human error, carelessness, deliberate acts or mistakes, or because of natural disasters or marine accidents especially for refineries or tankers shipping any form of petroleum product.
What makes an effective sorbent?
A successful sorbent material should have a high surface area to volume ratio, including external and available internal surfaces. For viscous oils that are unable to flow rapidly into a sorbent material, the performance will be determined by the available external surface area.
How does vermiculite absorb oil?
Both expanded and hydrophobic vermiculite showed higher values than walnut shell because of its higher porosity value. The external surface of the hydrophobic vermiculite had a wax coating, which resulted in adsorption followed by absorption of oil (Mysore et al., 2004) .
What are the pros and cons to using oil skimmers?
The main advantage of this type of skimmer is that, the oil that is collected can be recycled. A couple of disadvantages of this type of skimmer is that it can mainly be used on cal waters and it is prone to becoming jammed and clogged by floating debris especially ice.
