Order to Trial EVTN Underwater Voraxial Separator
Enviro Voraxial Technology, Inc. has received a purchase order to deploy the underwater version of EVTN’s high volume Voraxial 4000 Separator. EVTN envisions its underwater design as the core technology for an advanced generation of skimmer vessels to facilitate the Gulf clean-up effort and to effectively protect the environment from future offshore oil spills. Other technologies that have been deployed in the Gulf followed a similar trial process. The new Underwater Voraxial oil recovery method allows the operator to separate oil from water in the ocean. By conducting the separation in the ocean, the vessels can skim oil for 10 times longer since the amount of water collected in the holding tanks is reduced by 90%.
Marine Oil Spills and Response Options
Marine oil spills are subject to natural processes, which alter oil's physical and chemical properties. These factors ? as well as the type of oil spilled, the magnitude of the spill, and the physical conditions of the spill site ? determine the appropriate response for spill cleanup. Response options include mechanical recovery, chemical treatment and in-situ burning. Every spill scenario is unique and constantly changing. Careful assessment by experienced personnel is required for effective response performance. Natural spreading of the oil spill is a major factor in determining the response option most likely to succeed. The number and availability of personnel and equipment is also a major consideration.
Ro-Clean Presents New Disc Skimmer
Ro-Clean Desmi has introduced a new disc skimmer for the recovery of floating oils - Ro-Disc, a high efficient skimmer for inland waters and industrial process applications such as separators and tanks. Ro-Disc has a single bank of rotating oleophilic (oil attracting) discs driven by a hydraulic motor. Oil is recovered from the water's surface as it sticks to the disc surface. As the discs are rotated through the skimmer, head oil is scraped off and collected in the sump on an ongoing basis. Skimmed oil is removed by a hydraulically driven peristaltic pump, which is capable of running dry and will self-prime.
