In order to find a solution to the problem of the huge amount of water recovered together with the spilled hydrocarbons we need to know how these are pumped from the skimmers, because their knowledge will help us to find the best way to integrate the industrial separation methods presented in the previous post. Once [...]
In this post we will present different methods of oil/water separation and will analyze feasibility of using them to improve the efficiency of skimmers and pumping units. Gravity Differential Separation: The oldest and more extended separation method. It’s usually the first step in the treatment of oily water. Ruled by the Stokes' law is based [...]
The goal has been focused: We need to increase the efficiency of skimmers and improve the energy balance of decontamination operations. We could analyze step by step response operations up to final treatment trying to adopt better techniques and integrating low consumption motorizations, we will, but there is a job we can do before and [...]
As mentioned in previous post, the low efficiency of mechanical recovery devices causes high additional costs of decontamination and purification. Among the factors that impact on mechanical recovery efficiency we have cited the weather conditions and the type of skimmer. Improving weather is not something that is in our hands but improve existing skimmers performance [...]
Oil spill recovery operations have a huge energy cost as well as causing a secondary pollution caused by the use of polluting engines. Besides the use of antediluvian technologies, the largest contribution to energy consumption growth during the recovery operations is caused by the decrease in the efficiency of skimmers, or what is the same, [...]
Due to the limited efficiency of oil recovery systems in real conditions and in presence of waves the amount of water in the temporary tanks is too high. Depending on the environment the negative consequences can be increased. In an industrial environment the cost of treatment (separation / purification) of oil / fat [...]
Mechanical recovery is the most commonly used oil spill response technique and it’s accomplished by devices called "skimmer" which recover hydrocarbons and fats floating on the water surface. Several types of skimmer exist among which weir skimmers and oleophilic skimmers are widespread. The first ones, thanks to an onboard pump, create an inlet [...]
New technologies are based on energy saving and the use of "clean" energy. Process heat recovery is being implemented on industrial and domestic applications with great success. In the same way the use of renewable energy and energy sources existing in the place of exploitation produce significant economic savings and significant environmental benefits. By [...]
