Project summaryCurrently there are two methods used to remove spillage of petroleum products from water surface! the first one is based on application of various mechanical facilities for gathering up petroleum from water surface; the other one consists in application of dispersing agents (1). After cleaning of water surface both with mechanical means and through application of dispersing agents, thin "iridescent" film remains on the surface. In the modern view, a considerable part of the world ocean surface is covered with the film, which leads to changes of the planet's climate and aqueous biosphere. The given project supposes adequate researches to be conducted into laser radiation effect upon petroleum films on water surface under natural situations. It is anticipated that through an appropriate selection of the type of laser and the mode of action upon the film, a situation will arise when the petroleum film, the "iridescent" one included, will vaporize and come off from the water surface. In this case, the proportion of petroleum will become greater in the aerosol formed after evaporation, which can later on be sucked off from the laser beam effective zone, condensed and repurified with sorbents.
The infrared imager and the lidar-spectrurn fluorometer are supposed to be used in the capacity of the remote diagnostics facility to determine petroleum film parameters and as the online monitoring aids to follow temperature spatial and temporal variations of various film sections in the process of petroleum film laser action. The characteristics of the petroleum films obtained with the lidar and the IR imager are supposed to be promptly utilized in order to set the optimal mode of film laser vaporization and to monitor water purification degree. The IR imager (infrared optoelectronic instrument) is supposed to be used for initial remote detection of petroleum films on water surface and determination of its topology. Investigations are to be conducted which will enable to define limitations imposed by the weather conditions on possibilities to employ the IR equipment in the capacity of a remote detector of petroleum films over water surface. In the framework of the proposed project, a testing site is supposed to be erected in the water area of the Moscow Sea,, which will accomodate the following equipment:
- measuring IR imager,
- lidarspectrum fluorometer,
- industrial laser,
- the system's control equipment based on a IBM PC computer.
The computer will be used for acquisition and processing of the data obtained by the petroleum film detectors and diagnostic aids for solving the problem of determining the optimal mode of laser effect on petroleum films as well as for documenting the results.
The testing site is to be used for conducting appropriate investigations on diagnostics and laser vaporization of petroleum films of various thickness and composition under various weather conditions (water surface roughness, water and air temperature, wind force and direction, etc) and for defining the optimum operation algorithm of the natureoriented laser system with due regard for its placement on board a ship.
As a result of the investigations conducted, the principal requirements are to be formulated for research and experimental work on development of engineering specifications and manufacture of a prototype of the FILM shipborne nature-oriented laser system.
The FILM project fully addresses the objectives and goals of the International Science and Technology Center, since it reorients efforts of the scientific and supporting personnel, previously engaged in weapons development, towards scientific researches aimed at peaceful goals, at solving the problem of environmental protection in particular.
The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.
ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
