Bilge and Oily Water Treatment During Operation of Vessel
1 National University “Odessa Maritime Academy”, Odessa, Ukraine
ABSTRACT: Bilge and oily water (BOW) during vessel’s operation are the most large-tonnage type of waste and for their treatment all ships, in accordance with regulatory requirements [14], have to be equipped with special equipment – oily water separators. Under conditions of sea vessel operation BOW are process effluents that occur in the engine room, in cargo holds, as well as during the operation of the different equipment and deck machinery. At sea vessel’s operating conditions three main directions of BOW cleaning are now used: physical, chemical and biological. In most technological cases, they are used in combination with each other. The analysis of BOW separation methods based on these three directions has shown that they all could be characterized by one common drawback - unidirectional cleaning. During separation the final product – water is only one component of multiphase flow. It is very difficult to obtain secondary petrochemical products when modern methods of purification are used on the sea vessel during separation. Because of this reason in the research, a new method for BOW separation was developed. It is based on the use of a hydrodynamic process of supercavitation with artificial ventilation of the cavitational cavern. With local origin in the flow of a supercavitating cavern, there will always be saturated water vapor inside of it. The process of permanent water vapor selection from the cavern will ultimately contribute to the production of highly concentrated mixture of those petroleum products that form the initial mixture of BOW. In research, an assessment of the spatial stability of the cavitational cavern in the range of various cavitation numbers was done. During the study of BOW separation process it was found that decreasing of the working pressure inside the working chamber of the cavitation separator have to be always compensated by an increase in the temperature of the processed multiphase flow.
